In just few years, perovskite solar cells (PSCs) have made impressive advances with maximum power conversion efficiencies (PCEs) moving from 3.8% in 2009 to certified 22.1% in 2016. The PEPPY project has the overall objective of developing and validating in relevant environment at module level (TRL 4-5) a radically new class of highly efficient and stable organic-inorganic PSCs with outstanding performances: PCEs higher than 23% at cell level in laboratory and higher than 16% at module level. The goals will be achieved by means of a holistic and coordinated experimental and computational work aimed at the identification of the most relevant material compositions, device designs and price competitive fabrication processes of technologies with sufficient stability under strongly accelerated aging conditions (outdoor sun concentrator with tracking system), environmentally viable fabrication and deployment in the present energy scenario. To this purpose, the consortium proposes new multifunctional polymers as key ingredients for sealing and hole-transporter components, together with novel carbon-based back-electrodes (derived from biosourced polymers) replacing standard gold contacts. The project activities will be carried out by a strong and well-balanced Consortium, comprising top-level partners with outstanding experience in the PSC preparation: Dyesol (UK) as the global leader in the development of industrial technologies for the fabrication and commercialization of PSC modules, and PoliMI as highly qualified collaborator in the field of materials chemistry, synthesis and engineering. The success of PEPPY is then guaranteed by the credibility of the PI, who recently published a preliminary research on PSC in the top-ranked SCIENCE journal, and by the selected PI's team in PoliTO, which owns clear and complementary skills in materials chemistry, (photo)electrochemistry and computational methods as well as LCA and business/exploitation plans.
