The recent process and future of perovskite solar cells materials

Perovskite solar cells (PSCs) provide attractive prospects for the photovoltaic industry, but the harsh preparation conditions and stability of perovskite materials are still the biggest obstacles to the industrialization of PSCs. This review paper compares the differences in composition and working principle between dye-sensitized solar cells and PSC. It also reviews the optimization and development of electron transport layer, perovskite absorbers and hole transport layer in recent years. By analyzing the crystal morphology, grain size, internal and surface defects of each layer, it also highlights that surface/bulk passivation, composition and interface engineering are used to improve the photoelectric conversion efficiency and the stability of devices. At the same time, the research and development direction of PSC is prospected. It is believed that the industrialization of PSC will be accelerated through the efforts of scientists.
