Embodiment Construction
[0013] see figure 1 , the layered metal-nonmetal thin film solar cell of the present invention is formed by alternate lamination of at least two metal thin film layers and at least one nonmetal thin film layer, and the uppermost layer is a metal thin film layer, which constitutes the positive electrode layer of the battery, and the lowermost layer is a metal thin film layer. The thin film layer constitutes the negative electrode layer of the battery. All the film layers are laminated to form a fine superlattice structure, and are arranged in an orderly geometric and photoelectric manner. The surrounding edges of the battery are insulated and etched. The thickness of each layer is between 0-2000 between nanometers but not zero. Such as figure 1 Shown, 1 is the first layer, also is the first metal thin film layer, and constitutes the positive electrode layer of battery, 2 is the second layer, also is the first non-metal thin film layer, 3 is the third layer, also is the second ...

Abstract
The invention relates to a layered metal and non-metal film solar battery, which consists of at least two layers of metal film layers and at least one non-metal film layer through alternate lamination, wherein the topmost layer is the metal film layer forming a positive electrode layer of the battery, the bottommost layer is the metal film layer forming a negative electrode layer of the battery, all of the film layers are laminated for forming ultra-fine superlattice structures and are in geometrical and photoelectric ordered arrangement, the peripheral edges of the battery are subjected to insulation etching processing, and the thickness of each layer is between 0 and 2000 nanometers but is not zero. The layered metal and non-metal film solar battery belongs to a high-photoelectric-conversion-efficiency ultra-fine solar battery based on green materials such as ordinary metal and non-metal, the technical process is simple, and the market potential is huge.
Description
technical field [0001] The invention relates to a solar cell, in particular to a layered metal-nonmetal thin film solar cell. Background technique [0002] The development and utilization of solar energy is one of the most important ways for human beings to solve the energy crisis and environmental crisis, and the development of green and high-efficiency solar cells is the key technology and link for the widespread application of solar energy. At present, silicon-based batteries, including thin-film batteries and silicon wafer batteries, have low photoelectric conversion efficiency and limited use value, but solar cells with a stable efficiency of more than 23%, such as stacked gallium arsenide or copper indium gallium selenide or germanium-based thin-film batteries , There are problems such as scarcity or toxicity of materials, and the process is complicated, so there is no potential for wide application in society. Contents of the invention [0003] The object of the pr...
