In the renewable energy field, the use of hybrid perovskite materials has opened up new directions to fabricate cost‐effective and highly efficient photovoltaic devices. Despite impressive power conversion efficiency (PCE), exceeding 25.2%, demonstrated on lab‐scale devices, scalability and stability of device are still topical issues. In this context, large‐area deposition procedures and automated fabrication protocols are required to achieve high throughput serial production of modules and panels. In this work, a spray‐coated tin oxide (SnO2) layer processed at low temperature for the realization of planar perovskite solar cells (PSCs) and modules is demonstrated. Using sprayed Np‐SnO2 as the electron transport layer (ETL), a CH3NH3PbI3‐based solar device shows a maximum PCE of 16.77% (avg. 15.01%) comparable to 17% (avg. 15.5%) with respect to spin‐coated Np‐SnO2. Unencapsulated spray‐ and …
