| Abstract |
The perovskite solar cell is a next-generation solar technology that is expected to realize low manufacturing cost and high output. In order to improve the efficiency of perovskite solar cells, research and development to improve the related new material development and interface formation process is being actively carried out worldwide. Among them, it is essential to establish a systematic development plan in the future to establish a theoretical basis for improving solar cell characteristics by improving the interface formation process. In this paper, the effect of the quantified defect density at the solar cell interface on the solar cell characteristics is presented using a simulation technique. It is confirmed that the perovskite-electron-transporting layer interfacial trap has a greater effect on the reduction of solar cell efficiency than the perovskite and the hole-transporting layer interfacial trap, and has a greater effect on the reduction of the temperature coefficient of solar cell efficiency. In the future development of perovskite solar cells, it is judged that the development of a process for controlling defects at the interface between the perovskite and the electron transport layer has the highest importance |
