Combined solar battery capable of improving solar energy utilization rate

Abstract

The invention relates to a combined solar battery capable of improving the solar energy utilization rate. The combined solar battery comprises a battery body, wherein the battery body structurally comprises microstructural polymer heterojunctions and nanocrystalline discrete island array heterojunctions; the outermost layer of the battery body is conductive glass; an energy level regulating layer,an electrolyte, a dye sensitization layer, a nanocrystalline semiconductor layer and a metal electrode layer are sequentially arranged in the conductive glass from top to bottom; the conductive glasscomprises a positive electrode and a negative electrode; and after sun light passes through the positive electrode and penetrates through a heterojunction interface, the electrode becomes the negative electrode. The combined solar battery has the advantages that the structure is simple; the energy consumption for battery preparation is low; the energy source recovery period is short; nontoxicityand no pollution are realized in the production process; the appearance is ultrathin; the weight is light; particularly, the mechanical softness is realized; the combined solar battery can be attachedonto the surface of various articles on the premise of not occupying the space resources and not damaging the surface features of an original covered article; and the combined solar battery is worthyof being popularized and used in a large scale.

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...

Problems solved by technology

[0011] 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.
