Abstract

Perovskite solar cells (PSCs) are an emerging photovoltaic technology. PSCs with a power conversion efficiency of 25.2% have been demonstrated. Apart from the encouraging progress made in the efficiency, continuous improvement in operational stability is essential if the PSC technology is to become one of the commercially viable photovoltaic options for applications in renewable energy. In parallel to the development of high-performance PSCs using environmental-friendly solution fabrication processes, incorporation of process-compatible high-quality metal oxide interlayers for enhancing the stability of PSCs, through passivating the interfacial defects at the perovskite/contact interfaces, enhancing charge extraction, and retarding of the moisture encroachment, is needed. This review discusses the recent research progresses made in the development of different metal oxide interlayers for applications in PSCs, highlighting the functions, process compatibility and advances in high performing stable PSCs.
