How to use Synchrotron Soft X-Ray for Analysis of Perovskite Solar Cell

Abstract

Organic methyl ammonium lead halide crystal (e.g. CH3NH3PbI3) can be Perovskite structure with good semiconductor characteristics for solar cells over 24% photoenergy conversion efficiency. The significant point of the perovskite crystal is that it can be prepared by printing methods on substrates (e.g. spin coating, doctor blading, ink jet printing and so on). However, the physical phenomena of perovskite solar cells are still not clear for the higher conversion efficiency and higher stability against circumstances. In order to manage the issues, synchrotron soft X-ray can be a quite strong tool for the analysis. In this conference, the points about how to use synchrotron soft X-ray on perovskite solar cells will be discussed.
