As a renewable clean energy, solar energy is the focus of new research, development and utilization. The most direct and effective means of utilizing solar energy is photovoltaic cells, and the core of photovoltaic cell industry development is photovoltaic materials, whose type and quality directly affect the cost and photoelectric conversion efficiency of photovoltaic cells.  At present, the main kinds of photovoltaic include crystalline silicon, cadmium telluride(CTe) based series, copper indium gallium serenade (CIGS) based series, heterojunction (HJT) and so on. Solar thermal is widely used in domestic and commercial water heater, solar house, solar greenhouse, etc.

Vacum Coating is widely used in solar photovoltaic and solar thermal filed.
