Interface passivation strategies for stable industrially manufactured perovskite solar cells. (Research)

To tackle climate change and increase access to cheap electricity, photovoltaic technology (PV) needs continuous development. With a world record light to power conversion efficiency of 25.7 %, almost on par with the much older mono-crystalline silicon solar cells, perovskites are considered the future of PV. However, they have two big disbenefits, its stability is far away from long-term operation (due to e.g. ion migration) and its electrical performance can still be increased significantly (interfaces are a big source of recombination). Thus, in this proposal we will study, develop and integrate perovskite interface passivation strategies based in inorganic dielectric layers to boost the cell's optoelectronic performance by lowering interface recombination velocity – today's biggest performance loss -while contributing to mitigate ion migration. The studied manufacturing will be large-area and low cost avoiding the use of complex laboratory methods.
