Towards commercialisation of Perovskite PV and development of dedicated manufacturing equipment (EUPI-PV Partnership)

Metal halide perovskite solar cells have attracted much attention because of their low-cost fabrication and high efficiency. In addition, tandem devices, especially perovskite-Si tandems, are expected to play an important role in perovskite commercialisation. Poor stability of these devices remains however the key challenge in their path toward commercialisation. To overcome this issue, a robust encapsulation technique by employing suitable materials and structures with high barrier performance against the external environment must be developed to protect perovskite devices. Dedicated manufacturing processes and equipment need also be demonstrated. Therefore, proposals are expected to address all of the following aspects:

• Demonstrate effective strategies to enhance the optoelectronic properties, performance and stability, and minimise the environmental impact of perovskite devices;
• Scale-up reliable deposition of high-quality perovskite films over large areas, (overcoming the degradation of efficiency as device/module areas scale up) but also patterning and interconnections to connect individual cells into modules;
• Demonstrate internal and external encapsulation structures as protection from extrinsic environmental stressors, such as moisture, oxygen, heat, and illumination;
• Develop module designs considering recyclability requirements and restrictions as to the control and management of toxic Pb2+ that could be produced by the irreversible deterioration of the perovskite materials;
• Assess performance and reliability according to international standards and compared with well-established PV technologies; develop and apply test protocols for performance and reliability tailored to the features of perovskite and/or perovskite-Si tandem technology.
• Demonstrate suitable equipment adapted to the specific requirements of perovskite (or perovskite-Si tandem) production process.

Proposals are expected to involve multidisciplinary consortia including at least one perovskite or equipment manufacturer.

Whenever the expected exploitation of project results entails developing, creating, manufacturing and marketing a product or process, or in creating and providing a service, the plan for the exploitation and dissemination of results must include a strategy for such exploitation. The exploitation plan should include preliminary plans for scalability, commercialisation, and deployment (feasibility study, business plan) indicating the possible funding sources to be potentially used (in particular the Innovation Fund).

This topic implements the co-programmed European Partnership for Innovation in Photovoltaics (EUPI-PV). As such, projects resulting from this topic will be expected to report on the results to the European Partnership for Innovation in Photovoltaics (EUPI-PV) in support of the monitoring of its KPIs.
