Abstract

The invention relates to a combined solar cell capable of improving the utilization rate of solar energy, which comprises a cell body, wherein the structure of the cell body includes a microstructuralpolymer heterojunction and a nanocrystalline discrete island array heterojunction; the outermost layer of the cell body is conductive glass, the conductive glass includes an energy level regulation layer, an electrolyte, a dye sensitization layer, a nanocrystalline semiconductor layer and a metal electrode layer in turn from top to bottom; the conductive glass is divided into a positive electrodeand a negative electrode; and the sunlight passes by the positive electrode, penetrates through a heterojunction interface and is turned into the negative electrode. The combined solar cell has the advantages that the structure is simple, the energy consumed by preparing the cell is less, and the energy recovery period is short; the combined solar cell is non-toxic and pollution-free in the production process, ultra-thin in volume and light in weight, has mechanical flexibility in particular, can be mounted to the surface of various objects without occupying space resource and destroying surface characteristics of the original covered object, and is worthy of large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of thin-film solar cells, in particular to a combined solar cell that can improve the utilization rate of sunlight energy. Background technique [0002] At present, various types of solar cells that have been applied to different degrees mainly include: silicon-based solar cells (such as monocrystalline silicon, polycrystalline silicon, amorphous silicon and other thin-film solar cells), multi-component inorganic compound batteries (based on inorganic salts such as gallium arsenide III-V compounds , cadmium sulfide, copper indium selenium and other multi-component batteries), nanocrystalline solar cells (NPC), and organic polymer solar cells. The basic working principle of solar cells is the p-n junction photovoltaic (photovoltaic) effect. In order to improve the photoelectric conversion efficiency of solar cells, international research work mainly focuses on material physics and new structures of solar cells. [000...

AI Technical Summary

Problems solved by technology

[0013] Although the technology of traditional silicon crystal batteries is mature, most of them have a layer of tempered glass as protection due to the silicon crystal material, which causes problems such as heavy weight, inconvenient portability, poor shock resistance, high cost, easy to break, and high energy consumption in the production process.
