Review on Enhancement of Stability and Efficiency of Perovskite Solar Cell

Abstract

Abstract For photovoltaic applications, organic-inorganic hybrid perovskite solar cells have a extensive array of characteristics, including elevated absorption coefficients, exceptional carrier mobility, long charge carrier diffusion lengths, low cost, and incredible development. As emerging solar cell with thin film technology, these solar cells have generated many concerns. The elevated efficiency along with the low cost of materials and process are the main benefit of this cell over commercial silicon or other organic and inorganic solar cells. The foundations behind the optoelectronic description of perovskite materials and important methods for creating highly efficient perovskite solar cells have been covered in this paper. The degradation mechanisms of unstable perovskite materials and the associated solar cells are discussed. There are two more ways to increase the stability of perovskite materials and perovskite solar cells: interface engineering between the hole transport layer and the perovskite active layer and interface alteration between the electron transport layer and the perovskite layer. The future development of PSC architecture engineering is finally given a perspective and outlook.
