SoloPower devices are fabricated on copper-indium-gallium-selenide, Cu(In,Ga)Se2, or CIGS group of materials using a proprietary and novel electrochemical process. The solar cell is built on a thin flexible foil substrate.

SoloPower believes that its electrochemistry based CIGS technology will enable production of high efficiency solar cells at a fraction of the cost of traditional CIGS fabrication methods. CIGS material is already proven for high efficiency solar cell fabrication with state-of-the-art efficiency approaching 20%.
