Perovskite-based mesoscopic solar cells have recently attracted enormous attention from academic and industrial researchers due to high power conversion efficiency while still holding the promise of many of the advantages of dye solar cells, such as high performance under diffuse and non-ideal light conditions, ease of manufacture and low embodied energy. However, commercialisation of perovskite solar cells will depend on the scalability of its assembly processes and adequate durability.

In this work, the durability of the device and some of the components of the perovskite solar cells were evaluated under different storage conditions. Results will be discussed in terms of degradation mechanisms. Screen printable blocking layers and ultrathin mesoporous-TiO2 films were developed in view of industrial scalability and compared with traditional spin coating and multi-pass spray pyrolysis processes. Good results with high performance and excellent consistency from devices based on scalable processes will be presented.
