Analysis of strategies for improving the application performance of perovskite solar cells

Under the social background of energy shortage, climate change and environmental pollution, peoples demand for renewable energy is increasing. Solar energy is an important choice, but the problem of cost efficiency and low of traditional silicon solar cells has not been effectively solved. Perovskite solar cells (PSCs) were discovered in 2012 by researchers who overcame the conventional issues. The PSCs are made up of three layers of electrodes: a perovskite layer, an electron transport layer, and a hole transport layer. In-depth descriptions of the n-i-p and p-i-n structures are also provided. PSCs also have difficulties with environmental safety, dependability, and stability. Interface engineering is an important strategy, which can improve the performance and life of the battery by optimizing the energy level matching between various layers, defect passivation and carrier transport. With the progress of science and technology and the optimization of equipment, the problem of non-uniformity of perovskite layer on rigid non-planar surface can be significantly improved by using ultrasonic spraying technology. Through the optimization of the production process and composition configuration of PSCs, some related discussions are carried out, hoping to improve and help the scientific research project and some energy industries.
