Abstract

The invention discloses a reflective concentrating photoelectric heat cogeneration device based on perovskite solar cells, which includes a concentrating curved surface, a vacuum heat collecting tube and a frame, the concentrating curved surface and the vacuum heat collecting tube are all arranged on the frame, and the vacuum collecting The heat pipe is set on the focal line of the concentrating surface, and the inner side of the concentrating surface is coated with a silver-plated layer and a perovskite battery plate in sequence. It improves the power generation efficiency and at the same time exports excess heat to avoid overheating of the solar panels caused by part of the solar energy not being absorbed by the panels, improves the utilization rate of solar energy, and realizes the combined production of light and heat.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a reflective concentrating photoelectric heat cogeneration device based on perovskite solar cells. Background technique [0002] Solar energy, as a sustainable and clean energy source, is an ideal renewable energy source. In addition to the limitations of the material properties of the photovoltaic cell itself, the utilization of solar energy by photovoltaic cells has the following technical limitations: solar cells can only partially utilize the solar spectrum; the solar energy density is low, and the actual working efficiency of power generation devices is difficult to improve. The highest theoretical photoelectric conversion efficiency of solar cells is only 31%, and the energy output form of solar energy utilization devices is single. Perovskite solar cells are a type of high-efficiency solar cell system prepared by printing. The solar cells only use sunligh...
