In planar perovskite solar cells (PSCs), the electron transport layer (ETL), with the function of transporting electrons and blocking holes, plays a significant role in determining the photoelectric conversion properties. Thus, it is crucial to exploit potential ETL materials for improved performance. Herein, we demonstrate efficient planar PSCs employing ultrathin Nb2O5 films as ETLs fabricated by...
Accumulated dust on solar photovoltaic (PV) modules can significantly decrease their energy output in desert environment. Therefore, cleaning the deposited dust on the PV module surface is crucial in engineering applications to maintain the high power output of solar power plants, especially in desert areas. Nevertheless, it is difficult to predict the reasonable cleaning frequency for PV modules...
