Solar Photovoltaic industry requires the foundation of vacuum and support with equipment in its key processes, to achieve cost reduction, low pollution and generation of high benefit. Due to environmental consciousness and crisis of depleting non-renewable energy, the development of solar energy, wind power, geothermal and bio-energy and other technologies are getting more attention, particularly solar energy, which is taking the place of conventional fossil fuels. The development of silicon wafer materials, composite crystallized materials and thin film solar PV components, which includes the steps executed in vacuum system requiring high cleanliness and negative pressure environment to keep PVD and CVD processes under high vacuum degree, as well as employs vacuum coating process in the development of clean energy, power supply to communication and information products, not only solved the problem of depleting energy but also that of environment.

　Htc key vacuum technology competence in photovoltaics lies in thin-film technologies, which are used to manufacture different kinds of solar cells. Htc in this area supplies highly-productive in-line coaters in all customary to create innovative, reliable production technology. Thanks to its capacity to make modern photovoltaic technologies ready for series production in a very short time,Htc customers gain significant competitive advantages with respect to product attributes and costs.
