CIS Solar


Sustainable energy for a sustainable environment

Photovoltaic converts sunlight into clean electricity. It makes no noise and can be used where energy is needed. With the proper mixing of copper, indium, selenium, and sulphur (CIS), a thin film (about 1/100th of a normal copy paper thick) sunlight absorber can be fabricated. This thin film can be coated on metal sheet, making it strong, light-weight and conformable to curve surface.



We developed a CIS absorber deposition process by electrodeposition (plating). Ions dissolved in electrolyte are driven by electric charges from anode to cathode to form a thin film semiconductor with the correct proportions of CIS. Thin film can be coated on single side, or both side of the metallic substrate. When coated on both side, the absorber can simultaneously absorb light from front and back, making it easier to use.

Our Company

CIS Scientific is a private laboratory founded in 1996. Our researches cover compound semiconductor materials such as CIS, GaAs, GaN and other metallic films for the applications of photovoltaic, LED, power electronics, RF, and MEMS.
