Abstract

A system and a method for manufacturing semiconductor thin film solar cell are provided. The system comprises: channel heating means with several temperature zones (70); a plurality of thermo-chemical reaction containers (71) for containing thin film substrates; a rotation mechanism (72) driving the thermo-chemical reaction containers (71); a gas supplying station (73) for controlling the ambient; a control station (74) for controlling the relative movement between the channel heating means with several temperature zones (70) and the thermo-chemical reaction containers (71). The temperature of the substrates in the thermo-chemical reaction containers (71) varies continuously and stably following the relative movement between the production lines and the channel heating means with several temperature zones (70), thus the thermo-chemical reaction which is required in the production of semiconductor thin film solar cell is accomplished.

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 manufacturing system and a manufacturing method of a copper indium gallium selenide thin film solar cell. 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 depletion. Inexhaustible renewable energy has become more and more urgent, and solar cells based on photovoltaic effect are such a new renewable energy. At present, people pay more and more attention to the development and utilization of solar energy, and the market demand for new solar cells with larger area, lighter and thinner and lower production cost is increasing day by day. Among these new solar cells, the silicon...
