Metal halide perovskites in the last decade emerged as a new class of materials for highly efficient solar cells, with the power conversion efficiency reaching up to 25.7%. Perovskite photoactive materials offer inherent advantages leading to high power conversion efficiencies, such as long carrier diffusion lengths, high carrier mobilities, low exciton binding energies, high absorption coefficients and band gap tunability via interchanges of the precursor components. An important benefit of these materials is the possibility to deposit its thin films via solution-based processing at low temperatures. The use of plastic foils also opens the possibility for a PV product to offer a range of new value propositions, where non cost-related factors can provide an important leverage, such as light weight, high specific power, or ease of integration with various surfaces. The presentation will review the advancements in this rapidly developing field, and Saule's approach to turn it into a commercially viable product.
