Solar photovoltaic power generation is a kind of power generation method that directly transforms light energy into electric energy without thermal process. It includes photovoltaic power generation, photochemical power generation, photo induction power generation and photobiological power generation. Photovoltaic power generation is a direct power generation method that uses solar grade semiconductor electronic devices to effectively absorb solar radiation energy and convert it into electrical energy, which is the mainstream of solar power generation. In photochemical power generation, there are electrochemical photovoltaic cells, photolysis cells and photocatalysis cells. At present, photovoltaic cells are widely used.

Photovoltaic power generation system is mainly composed of solar cell, battery, controller and inverter. Solar cell is the key part of photovoltaic power generation system. The quality and cost of solar panel will directly determine the quality and cost of the whole system. Solar cells are mainly divided into crystalline silicon cells and thin-film cells. The former includes monocrystalline silicon cells and polycrystalline silicon cells, while the latter mainly includes amorphous silicon solar cells, copper indium gallium selenium solar cells and cadmium telluride solar cells.

Thin film solar cell is a kind of solar cell based on silicon, cadmium sulfide, gallium arsenide and other thin films. Thin film solar cells can be made of light, low-cost substrate materials (such as glass, plastic, ceramics, etc.), which can generate voltage. The thickness of the film is less than 1 micron, which is convenient for transportation and installation. However, there are some defects in the films deposited on heterogeneous substrates. Therefore, the conversion efficiency of CdTe and CuInGaSe solar cells in large-scale production is only 12% to 14%, and the theoretical upper limit is up to 29%.

HCVAC vacuum provides technologies and coating materials for the production of thin-film solar cells and organic solar cells, as well as thin-film processes for improving the efficiency of crystalline silicon solar cells. In the process, we combine the most advanced automation technology with the best process, such as the coating equipment robot assisted loading technology which can guarantee the maximum production rate.

We offer a wide product portfolio covering deposition processes for front electrodes consisting of transparent conductive oxides (TCO) and equipment for deposition of copper, indium, gallium, selenium or a-Si: H (doping, intrinsic) for the production of metal back electrodes.
