Research on solar cells based on electron transport layer

Abstract

In today ' s world, the energy crisis and environmental pollution are becoming more and more serious. As a renewable energy, solar energy has become one of the important means to meet the global energy demand. Making solar cells using volt effect is an effective way to convert solar energy into electricity. In order to employ solar photovoltaic power generating technology with high efficiency and cheap cost, new solar cell research and development is being done. Among them, organic solar cells are considered as one of the promising solar photovoltaic technologies because of their light weight, simple preparation process, good flexibility and easy to achieve large area processing. While perovskite solar cells are developed in a high speed in recent year because of their simple production and long service life. The urgent problem in this field is further improve the energy conversion efficiency of solar cells. In order to solve these problems, we study the structure principle and electron transport layer of solar cells, and get solutions by analyzing these problems.
