Abstract

The invention provides a solar graphene cell, and relates to the technical field of solar cells. According to the invention, the technical problem that a traditional solar cell is low in photoelectricconversion efficiency, poor in performance, high in price and not beneficial to large-scale production and application can be solved. Therefore, the solar graphene cell effectively improves the photoelectric conversion efficiency. Meanwhile, the photoelectric conversion efficiency reaches 12.11%. The performance of the cell is obviously improved. In addition, the production cost is effectively reduced in the preparation process. The solar graphene cell is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar graphene cell. Background technique [0002] With the development of economy and progress of society, the problem of energy shortage is becoming more and more prominent. As an inexhaustible renewable new energy source, solar energy has advantages that other types of energy sources cannot match. Therefore, the development and utilization of solar energy has attracted more and more attention. As a new type of solar cell, dye-sensitized solar cells have attracted extensive attention due to their potential low cost and high photoelectric conversion efficiency. Moreover, the photoelectric conversion efficiency has exceeded 11%, which is close to the conversion efficiency of commercial polycrystalline silicon solar cells, and the preparation technology of dye-sensitized solar cells is simple and the production cost is low, showing its potential commercial application pros...
