​Charge accumulation at the electron and hole transport layers generates anomalous electrical behavior in perovskite solar cells (PSCs). Hysteresis in the current-voltage characteristic and recombination at the interfaces are the clearest manifestations of this phenomenon, which compromises device performance and stability. In this study, we explained the underlying charge‐carrier dynamics of a hysteresis observed and hysteresis-free PSCs by analyzing their transient photocurrent response. ​

​High-efficiency silicon heterojunction (SHJ) solar cells (Fig. 1), which use a crystalline silicon (c-Si) wafer as an optical absorber and thin-film layers to form their electrical contacts, have the potential to gain a substantial share in the commercial photovoltaic (PV) market in the future. Currently, the world-record efficiency of 26.7 % is achieved with SHJ technology by placing both contacts in an interdigitated back-contact design. The KAUST Photovoltaics (KPV) Lab, led by Prof. Stefaan De Wolf, which is part of the KAUST Solar Center (KSC), is dedicated to the development of high-efficiency silicon-based solar cells, using SHJ solar cells as a core technology, and to tailoring such solar cells specifically for use in hot and sunny climates.
