High Performance Hybrid Perovskite Solar Cells Using Electron Beam Evaporated Processed TiOx as Electron Transfer Layer

Abstract Details

2015, Master of Science in Polymer Engineering, University of Akron, Polymer Engineering.
Perovskite hybrid solar cell has been one of the most outstanding novel solar cell in the past five years. The power conversion efficiency has been increased from 3.9% to over 19%. Three major structure has been developed and several modification for the perovskite active layer, hole and electron transport layer, electrode, device fabrication has been conducted. However, short term stability and its fabrication process still limits its bulk production and commercialization. In order to make perovskite solar cell be competitive to traditional silicon solar cell, such two issues must be resolved. There are two chapters in this thesis In chapter 1, we give a general introduction for the development of perovskite solar cell, including the perovskite material, working mechanism, device structure, hole and electron transport layer, processing of active layer, and stability In chapter 2, To accelerate industrialization of perovskite solar cells, we report a large-scale, easy manufacturing method via applying electron-beam (e-beam) evaporation to produce high quality TiOX layer (eb-TiOX) as the electron transfer layer (ETL) in conventional structure perovskite solar cells. By using the e-beam processing, the originally high-temperature processing and complicated film fabricating procedures for TiOX layer is eliminated. Instead, high quality TiOX layer with precisely controlled film thickness is realized. By using the eb-TiOX as the ETL in perovskite solar cells with a conventional structure, the average power conversion efficiency reached a high value of 14.73% and an extremely high short-circuit current density of 27.83 mA/cm2 has been realized after a short-time light soaking process.
