Abstract

The invention discloses a system and a method for manufacturing a semiconductor thin film solar cell, which can provide continuous and stable thermalchemical temperature-variable reaction conditions in the process of generating a compound thin film by a thermalchemical reaction. The system and the method are particularly suitable for continuously, stably and controllably manufacturing absorbing layers of copper-indium-gallium-selenium polycrystalline thin film solar cells with high yield.

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, especially a manufacturing system and method for 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 the situation of depletion. Therefore, seeking low-carbon emissions and Inexhaustible renewable energy is becoming more and more urgent, and solar cells based on the photovoltaic effect are just such a renewable new energy. At present, people pay more and more attention to the development and utilization of solar energy, and the demand for new solar cells with larger area, lighter and thinner and lower production cost is increasing day by day...
