Abstract

The invention discloses a laminated solar cell and a manufacturing method thereof. An amorphous silicon (a-Si:H) is used as a top layer of battery and absorbs blue lights and green lights with shorter wavelengths; and a compound semiconductor of copper indium selenide is used as a bottom layer of battery and absorbs yellow lights, red lights and infrared lights with longer wavelengths (the wavelength reaches 1150 nm). The bottom layer of a copper indium selenide film battery is obtained by ink-printing semiconductor nanometer particles and has the characteristics of low cost, high efficiency,and the like. The top layer of an amorphous silicon film battery is obtained by a PECVD (Plasma Enhanced Chemical Vapor Deposition) deposition process and has the characteristics of cheap price and favorable work under the condition of weak light. The laminated solar cell has the characteristics of low cost, high efficiency, stability, and the like.

Description

technical field [0001] The invention relates to the technical field of photovoltaic solar cell manufacturing, in particular to a semiconductor thin film solar cell, in particular to a semiconductor thin film laminated solar cell and a manufacturing method thereof. Background technique [0002] With the continuous increase of energy consumption, as the main source of energy, the carbon dioxide emissions caused by the extensive use of oil and coal seriously pollute the ecological environment, and oil and coal resources are also facing the situation of depletion. Therefore, seeking low-carbon emissions and Inexhaustible renewable energy is becoming more and more urgent, and solar energy is just such an inexhaustible renewable new energy. People pay more and more attention to the development and utilization of solar cells based on the photovoltaic effect, and the market demand for new solar cells with larger area, lighter and thinner and lower production cost is increasing. Amo...
