Metal halide perovskites constitute a very attractive class of materials for optoelectronic applications, such as solar cells, light emitting diodes, lasers and photodetectors. Most notably, solid-state photovoltaic devices based on these materials have reached power conversion efficiencies (PCEs) exceeding 25% within only a decade of academic research.
Perovskite solar cells have a great market potential, but there still remain few challenges, which need to be resolved to prove viability of the technology. Some of the well-known issues include material stability. Furthermore, cost-effective, reliable fabrication process capable of delivering highly efficient, large-area perovskite modules is of paramount importance.
This talk will outline industrial opportunities of perovskite PV technology, focusing on new value propositions and market versatility. Flexible perovskite solar cells successfully passing IEC-based accelerated aging tests, including damp heat aging, will be presented. Additionally, special aspect of the perovskite technology – all perovskite tandem PV  modules - will be discussed and their scalable fabrication process demonstrated, complemented with a robust encapsulation methodology.
