FILL FACTOR AND POWER CONVERSION EFFICIENCY SIMULATION OF HETEROJUNCTION ORGANIC SOLAR CELLS (P3HT/PCBM) USING ZNO AND PEDOT:PSS AS INTERFACIAL LAYER
Abstract
This article provides the simulation of fill factor and power conversion efficiency of heterojunctions organic solar cells using ZnO as electron transport layer (ETL) and PEDOT:PSS as hole transport layer (HTL). Heterojunction organic solar cells is a light sensitive material that converts the solar energy to electrical energy resources. Nowadays, to build the heterojunction organic solar cell is challenging with optimise the ideal materials to produce the higher electrical energy. Therefore, the structural design of organic solar cells and the material selection that have important significance for improving the conversion efficiency of organic solar cells. The method of this project using simulation tools. The main analysis to improve high fill factor and power efficiency of heterojunction organic solar cells (P3HT:PCBM) using ZnO as buffer layer with the optimised light intensity. The thickness of ZnO layer is 20nm. As a result, the heterojunction organic solar cell (P3HT:PCBM) at 0.10 light intensity found that the fill factor is 68.736810% and the efficiency reaches 11.3%. Finally, it is suitable for heterojunction organic solar cell applications.
