Abstract

Perovskite solar cell (PSC) is a type of third-generation hybrid solar cell based on organic-inorganic metal halide material, having the molecular formula of the type ABX₃. High efficiency, flexibility, cell architecture, and low-cost production of the PSC have caught the attention of researchers and technologists in the field. There is a tremendous growth of efficiency in a short period, i.e., 3.8% in 2009 to nearly 25% in 2020. This chapter discusses the fundamental principle used in PSCs. Its structure, various layers of the cell, and their significance will be conferred. The chapter will also cover the working of the solar cell and discuss the various parameters on which the efficiency of the solar cell will depend. Fundamental properties of PSCs will be examined like high optical absorption, tunable bandgap, high open-circuit voltage, which is one of the most promising aspects of the perovskite technology that the cells can generate under full sun illumination with low loss‐ in‐potential. In the end, drawbacks of PSCs, like stability and toxicity, will be analyzed and its reasons will be examined in brief.
