NREL Testing Confirms XsunX Cell Efficiency


XsunX Inc., the developer of CIGSolar, a hybrid, thin-film photovoltaic (TFPV) solar cell manufacturing process, says that the National Renewable Energy Laboratory (NREL) has certified the peak efficiency conversion of 16.36% achieved by XsunX for its copper indium gallium diselenide product.

Overall efficiency of tested samples ranged from 15.3% to 16.36%, producing an average efficiency of 15.91%. The sample provided to NREL was part of a 125 mm substrate that, after deposition, was sub-divided into quadrants to produce NREL device test structures and analytical equipment test structures.

The purpose was to provide a statistically significant body of data in support of XsunX's continuous process-improvement efforts, according to the company.
