Nanostructured Materials for Next-Generation Energy Storage and Conversion

Abstract

Perovskite solar cells (PSCs) have attracted more attention recently due to their high efficiency, low cost, and long charge carrier diffusion length. Generally, PSCs consist of three layers: the electron transport layer (ETL), the absorber layer (perovskite), and the hole transfer layer (HTL). To improve the device efficiency and enhance the cell stability of PSCs, great efforts toward developing novel and efficient electron and hole-transporting materials are needed. Due to its unique properties such as high efficiency, simple process and low-cost organic-inorganic halide perovskite solar cells (PSCs) provide great potential for the photovoltaics industry. Particularly, efficient interfacial layers are very important to enhance PSCs, as charge carriers need to have smooth transport pathway, and this can be achieved by manipulating the interfacial layers and by choosing suitable interfacial layers.
