HelioVolt Corporation is currently developing Copper Indium Gallium Selenide (CIGS) products using a solution-based
deposition of precursor films followed by rapid optical processing (ROP) to make CIGS. The ROP process takes less
than 1 minute of heating to convert the precursor stack to CIGS. Device made with ROP rival performance of device
processed using field assisted simultaneous synthesis and transfer (FASST®) processing.
