Perovskite solar cells are a promising photovoltaic technology that has recently achieved record power conversion efficiencies above 20%, yet only a few groups can reliably reproduce such high efficiencies on regular n–i–p architectures. This study provides detailed, reproducible fabrication protocols for achieving ≥20% power conversion efficiency in both regular n–i–p and inverted p–i–n perovskite solar cells, encouraging transparent reporting to facilitate reproducibility. The authors detail step‑by‑step fabrication procedures for both regular and inverted perovskite solar cell architectures to achieve ≥20% efficiency. Improved reporting standards are expected to accelerate progress in perovskite solar cell research.
Perovskite solar cells (PSCs) are currently one of the most promising photovoltaic technologies for highly efficient and cost-effective solar energy production. In only a few years, an unprecedented progression of preparation procedures and material compositions delivered lab-scale devices that have now reached record power conversion efficiencies (PCEs) higher than 20%, competing with most established solar cell materials such as silicon, CIGS, and CdTe. However, despite a large number of researchers currently involved in this topic, only a few groups in the world can reproduce >20% efficiencies on a regular n–i–p architecture. In this work, we present detailed protocols for preparing PSCs in regular (n–i–p) and inverted (p–i–n) architectures with ≥20% PCE. We aim to provide a comprehensive, reproducible description of our device fabrication protocols. We encourage the practice of reporting detailed and transparent protocols that can be more easily reproduced by other laboratories. A better reporting standard may, in turn, accelerate the development of perovskite solar cells and related research fields.
