Abstract

With the rapid development of society, energy consumption is increasing, and renewable clean energy is an important way to solve the problem of increasing energy consumption and how to protect the environment. Solar energy is a kind of sustainable development of clean energy. In the development of solar energy, polymer solar cells have attracted much attention due to low cost and good performance. With the deepening of research, the efficiency of polymer solar cells continues to increase, but there is still a problem of short service life, and how to improve the service life and efficiency of polymer solar cells has become a research hot spot. Since functionalized carbon nanomaterials have the advantages of good electrical conductivity, mechanical properties and strong chemical properties, this paper aims to improve the photoelectric conversion efficiency of polymer solar cells by applying functionalized carbon nanomaterials to polymer solar cells. Firstly, the working principle of solar cells was introduced. Secondly, graphene quantum dots functionalized carbon nanomaterials were prepared by hydrothermal method. Finally, graphene quantum dots are applied to polymer solar cells as acceptor materials and interface modification, and the photoelectric conversion efficiency of polymer solar cells is improved successfully. Simulation analysis shows that the prepared graphene quantum dots can improve the stability and efficiency of polymer solar cells, and play an active role in polymer solar cells.
