The National Renewable Energy Laboratory (NREL) confirmed that XsunX’s CIGS PV devices had reached a peak efficiency conversion of 16.36%. The samples tested had efficiency ratings that ranged between 15.3% and 16.36%, which lead to an average efficiency of 15.91%. XsunX supplied the NREL with a 125mm substrate sample, which after deposition was sub-divided into quadrants in order for NREL to generate device test structures and analytical equipment test structures. The organizations advised that this method was used in order to produce a substantial amount of data for XsunX to use as the basis of its future improvement efforts.
Robert Wendt, CTO at XsunX, commented, "NREL's official measurement of 16.36% supports our manufacturing approach and the viability of single cell processing. We believe the efficiency levels that we achieved can provide an economically viable process that we can offer the market. We are pleased with the results, but they are what we had planned for and expected. We believe that our approach lends itself to direct translation to production."
