Solid state alkylammonium lead halide perovskite solar cells have recently emerged as the latest thin-film photovoltaic device class. High power conversion efficiencies (22 %) and stabilities (> 1000 hours at 80 °C under 1 sun illumination) have been obtained using labscale processes using small cell areas. The building blocks of the perovskite materials are very low cost and the processing into the final perovskite is achieved in a low temperature fast process making these materials very cost efficient, allowing for a LCOE of 3-6 $cents/Kwh. These achievements are impressive yet to make perovskite solar cells a real alternative for photovoltaic devices they must be prepared using up-scalable methods and on larger area cells and modules.
