XsunX declared that the National Renewable Energy Laboratory (NREL) has verified the optimum conversion efficiency value of 16.36% for XsunX copper-indium-gallium-(di)selenide (CIGS) photovoltaic instruments.
XsunX manufactures solar cells using its hybrid, thin-film photovoltaic (TFPV) solar cell production method called CIGSolar. During the tests, NREL observed that conversion efficiency of the samples varied between 15.3% and 16.36%, resulting in an average conversion efficacy of 15.91%. The tested samples were a portion of a 125 mm substrate that was broken down into quadrants subsequent to the deposition to form analytical equipment test patterns and device test patterns of NREL.
XsunX’s proprietary technology uses co-evaporation to effectively control the complex CIGS layer deposition method by quickly depositing final-sized cells. It uses individual substrates with a size equivalent to that of silicon cells during its start and end. It eliminates performance failures occurrences when cells are either incompatible electrically in monolithic assemblies or sliced from rolls of CIGS material, and offers more accurate and smaller deposition environment.
The Chief Executive Officer at XsunX, Tom Djokovich stated that NREL’s certified measurements confirm that compact area co-evaporation delivers conversion efficacies equivalent to that of silicon. The company is excited about the prospects of its CIGSolar technology, he added.
XsunX’s Chief Technology Officer, Robert Wendt commented that the certified measurement of 16.36% by NREL complements the company’s production method and the feasibility of single cell processing. The company expects that the efficacy levels attained would allow the company to offer a cost-effective feasible process to the market, he added.
