One Step

Although ZnO is a compatible electron transport layer (ETL) for perovskite solar cells (PSCs), the fact that MAPbI3 easily undergoes thermal decomposition on a low-temperature processed ZnO surface limits the use of one-step deposition of perovskite and hence the resulting photovoltaic performance. The triple cation perovskite prepared with a one-step deposition method is demonstrated to be a stable light absorber in highly efficient PSCs with low-temperature processed ZnO as the ETL.

AbstractThe toxicity issue of lead hinders large-scale commercial production and photovoltaic field application of lead halide perovskites. Some novel non- or low-toxic perovskite materials have been explored for development of environmentally friendly lead-free perovskite solar cells (PSCs). This review studies the substitution of equivalent/heterovalent metals for Pb based on first-principles calculation, summarizes the theoretical basis of lead-free perovskites, and screens out some promising lead-free candidates with suitable bandgap, optical, and electrical properties. Then, it reports notable achievements for the experimental studies of lead-free perovskites to date, including the crystal structure and material bandgap for all of lead-free materials and photovoltaic performance and stability for corresponding devices. The review finally discusses challenges facing the successful development and commercialization of lead-free PSCs and predicts the prospect of lead-free PSCs in the future.
