Numerical analysis of hybrid perovskite solar cells using inorganic hole conducting material

摘要

Hybrid perovskite solar cells (HPSC) emerged recently as a possible alternative to Si based devices because of their high power conversion efficiency (PCE) and their potential low cost. However, in this work, we analyze numerically a potential inorganic hole conducting material (HCM) to replace expensive organic Spiro-OMETAD. HPSCs with various types of HCMs are computed using a solar cell performance simulator: wx Analysis of Microelectronic and Photonic Structures (wxAMPS). Among all the device structures, HPSC with inorganic Cu2O HCM shows the highest PCE exceeding 25%. Both defect free device and including defects were analyzed. Moreover, the performance degradation versus temperature has been investigated as a function of temperature. These results indicate the possibility to design HPSCs using cost effective and stable Cu2O HCM.
