Executive Summary: The objective of Deliverable D.1.3 is to realize carbon electrodes that open for scalable realization of highly efficient perovskite solar cells.

The Dyenamo carbon paste DN-CP01 fulfills two out of three of the targeted criteria of the Deliverable, i.e., i) conductivity and ii) chemical compatibility with the underlying layers. With regards to the third one, i.e., to tailor the charge selectivity of the carbon layer to promote high extraction of holes, Diamond has recognized the need to intensify the efforts on modifying either the interface between perovskite (or HTL) and carbon electrode, or the deposition techniques of the Dyenamo carbon paste, rather than solely adjust the properties of the carbon pastes themselves. This is mainly because poor contact/adhesion or interfacial properties between perovskite (or HTL) and carbon electrode would lead to high series resistance, energy mismatch and pronounced recombination at the interface, thereby severely limiting hole extraction and transport in carbon-based perovskite solar cells (PSCs).

Executive Summary: This deliverable is related to T2.1, which focuses on achieving the highest efficient PSC with a power conversion efficiency (PCE) ≥ 26% and proposing a roadmap to reach a PCE ≥ 27% with long-term stability. In this report, we detailed the optimization of perovskite composition and surface engineering, which enabled us to successfully reach this deliverable with the best-performing cells achieving a PCE of over 26.07%.

The compositionally engineered perovskite resulted in situ formation of [MTTZ]+ cation that increased the formation energy of iodine vacancies and enhanced the migration energy barrier of iodide and cesium ions, which suppressed nonradiative recombination, thermal decomposition, and phase segregation processes.

We have fabricated perovskite modules (PSMs) that achieved a record (certified) PCE of 23.2% with an aperture area of 27.2 cm². The encapsulated PSM retained 87% of its initial PCE after ~1900 hours of maximum power point tracking at 85°C and 85% relative humidity under 1-sun illumination following the ISOS-L-3 protocol. The decreased efficiency from 26.07% to 23.2% is due to the scaling effect.

Executive Summary: This deliverable is related to T2.2, which focuses on achieving the highest power conversion efficiency (PCE) of 22% with Pb-Sn based perovskites and outlines the roadmap to achieve 24% PCE with long-term stability.

In the following, we describe the composition, fabrication technique, and surface passivation that have enabled us to achieve a PCE of 22.31%. Our device uses an active layer with the composition Cs₀.₂₅FA₀.₇₅Sn₀.₅Pb₀.₅I₃, which is deposited on a Br-2PACz HTL by spin coating with the antisolvent procedure. The device is completed with an ETL composed of C₆₀ and BCP, both deposited by evaporation, as is the Ag electrode.

An important step in reaching this deliverable was the surface passivation with EDAI₂, which was performed using spin coating.

Executive Summary: A comprehensive study of laser-assisted glass frit encapsulation of Perovskite Solar Cells (PSCs) was performed. A 3D simulation study of the laser processing method, including finite element modeling of laser bonding and the analysis of glass frit chemical composition for laser-assisted glass encapsulation, was conducted.

Several sealing methods and glass frit compositions were assessed to achieve glass-to-glass bonding of both empty and perovskite solar cells. High reproducibility rates were achieved for small-size empty cells at moderate processing temperatures between 100-120°C. However, when the temperature was decreased to 85°C, reproducibility decreased, though still within an acceptable level.

For samples with solar cells fabricated by project partners, the reproducibility of laser bonding was affected by the cleanliness of the substrates. In the case of large-area modules, reproducibility rates remain lower than expected, but new developments have been implemented to mitigate the effects of laser beam distortion.

Executive Summary: In this report, we detailed the accelerated aging protocols which will be used by the partners involved in the WP5. 3 tasks in WP5 are related to the accelerated aging: ageing of materials in the task 5.1, single stress aging in the task 5.2 and combined stress in the task 5.3.
All these conditions are coming from ISOS recommendations in order to harmonize the protocols between partners and fit with standards or future standards. The materials or partial stacks will be mostly aged with light and temperature conditions. For cells and module tests the most important single stress aging conditions with light and/or temperature will be used with various electrical load. Regarding the multi stress aging, we will focus mostly about encapsulation (damp heat, thermal cycling) but also consider the most severe accelerated stress conditions by combining high temperature, humidity and continuous light.
The aging data will be merged, at least partially, in a common database. During the project, the output of the different aging tests will be compared with outdoor data in various locations in order to define the most important stress factors, establish accelerating factors and give lifetime prediction in operation.

Executive Summary: This report presents the development, functionality, and operation of a newly developed maximum power point tracker (MPPT) equipped with over 100 channels for simultaneous maximum power point (MPP) operation. This system serves as an important tool in WP 5, which focuses on the stability assessment of perovskite solar cells.

The MPPT system, consisting of custom-developed printed circuit boards and associated software, enables extensive aging and degradation studies under real-world stress conditions. The system was implemented and tested by aging over 100 perovskite solar cells for more than 100 hours under simulated sunlight.

By optimizing the choice of electronic components, the system was realized at a cost below 10€ per channel, i.e., per measured solar cell. Moreover, the protocol for outdoor aging in T5.4 is defined in this report.

Executive Summary: The decarbonization of the energy sector mandates a swift and widespread implementation of a clean and affordable energy infrastructure, mainly supported by photovoltaics (PV). The DIAMOND project joins 12 different Partners to develop ultra-stable, highly efficient, and low-cost perovskite PV with minimal environmental impact. Aiming to surpass all previous PV cell stability achievements, this project develops novel hermetic encapsulation approaches and highly stable device designs that are assessed using standardized and novel stability characterization methods. As part of DIAMOND, materials and cell stacks will be optimized to achieve efficiencies exceeding those of silicon PV. A fully printable module architecture allows rapid industrial up-scaling and local production in the EU, thereby reducing manufacturing costs.

Specific device designs that allow the lowest carbon-footprint, material criticality, and toxicity, along with increased recyclability, are targeted to minimize the ecological impact. DIAMOND‘s mission is to have a profound impact on the future development of the EU’s environment, economy, and society, thus paving the way for an EU-made sustainable energy technology with the lowest carbon-footprint that ensures full integration into the circular economy.

The consortium partners will execute the work packages, generate further knowledge and intellectual property by leveraging existing know-how. Moreover, sharing know-how demands an adequate management of prior intellectual properties. Thus, to build a solid foundation for a successful cooperation in DIAMOND, it becomes imperative to enable a smooth transfer for pre-existing IP and Foreground among partners. Furthermore, the expected outcome beyond this project regarding the innovative, scientific and/or technical aspects shall be protected by the consortium body.

The Intellectual Property Management Plan (Deliverable 7.2) shall function as a general guide, supplementary to the Consortium Agreement (CA) and the Grant Agreement (GA). In this deliverable, it is included the management of Background, transfer, ownership, and protection of Foreground as well as the settlement of dispute.

Executive Summary: The DIAMOND project focuses on developing ultra-stable, highly efficient, and cost-effective perovskite photovoltaic (PV) technologies to accelerate energy sector decarbonization. By leveraging innovative materials, scalable manufacturing processes, and advanced device designs, DIAMOND aims to surpass the performance of silicon PV while minimizing environmental impact. The project aligns with European energy priorities and seeks to disrupt the renewable energy market.

Deliverable 7.3 outlines a Technology Exploitation Roadmap to guide the commercialization and dissemination of DIAMOND’s outcomes. This plan includes the identification of key exploitable results, engagement with stakeholders, and alignment with market demands. The global perovskite solar module market is projected to grow at a compound annual growth rate (CAGR) of 43.4%, reaching USD 9,173.94 million by 2033, driven by material efficiency, diverse applications in IoT and electronics, and increased demand for renewable energy.

While Perovskite Solar Modules offer competitive efficiency and cost advantages, challenges such as long-term stability and established competition from silicon-based and other photovoltaic technologies must be addressed. DIAMOND’s strengths include its innovative approach and scalability, while weaknesses stem from limited industrial involvement in fabrication. Opportunities arise from growing market demand and EU energy policies, with threats including economic uncertainties and regulatory challenges.

This roadmap emphasizes ongoing communication with stakeholders, dissemination through scientific platforms, and strategic management of intellectual property to ensure successful market adoption.

The plan will evolve with project progress, with a final update at Month 36, to secure long-term sustainability and impact.
