Abstract

The invention relates to a solar cell capable of simultaneously performing photoelectric conversion and thermoelectric conversion, belonging to the technical field of solar photovoltaic power generation and thermoelectric power generation. The solar cell capable of simultaneously performing the photoelectric conversion and the thermoelectric conversion comprises a photoelectric conversion battery, a thermoelectric conversion battery and a heat sink, wherein the photoelectric conversion battery is stuck at the hot end of the thermoelectric conversion battery, and the heat sink is stuck at the cold end of the thermoelectric conversion battery. The solar cell can utilize the thermoelectric conversion battery and the heat sink to continuously absorb working waste heat in the photoelectric conversion battery while utilizing solar energy for performing the photoelectric conversion, thereby not only reducing the working temperature of the photoelectric conversion battery, but also improving the photoelectric conversion efficiency of the photoelectric conversion battery, and further enabling the solar cell to have higher conversion efficiency.

Description

technical field [0001] The invention relates to a solar battery capable of simultaneous photoelectric conversion and thermoelectric conversion, and belongs to the technical field of solar photovoltaic power generation and thermoelectric power generation. Background technique [0002] Solar energy is the leading renewable energy, and solar photovoltaic power generation is an important form of solar energy utilization. Solar photovoltaic power generation uses solar cells to directly convert sunlight energy into electrical energy, which has the advantages of less conversion links, high energy quality, short construction period, and close to zero-emission power generation. [0003] Solar photovoltaic power generation technology still has the following deficiencies in practical application: [0004] (1) At present, the photoelectric conversion efficiency of solar cells is between 15-20%, which only utilizes a small part of solar energy, and most of the solar energy is not fully ...
