Austin, Texas [RenewableEnergyAccess.com] In recently published findings announcing “a major leap forward for commercialization of CIGS photovoltaics,” the Stanbery model (or Intra-Absorber Junction) is termed a key accomplishment in the scientific community’s ongoing efforts to better understand the physics behind CIGS thin-film photovoltaics.The research explains much of the observed device physics and high performance characteristics of copper indium gallium selenide-based (CIGS) photovoltaics (PV). The experimental results confirming predictions of Dr. BJ Stanbery’s new theoretical model published in January represents four years of research by HelioVolt CEO Dr. BJ Stanbery and his team, HelioVolt Corp., copublished the findings with researchers from National Renewable Energy Lab (NREL). Dr. Stanbery has focused his efforts on commercializing CIGS ever since he set the world record for solar thin-film efficiency during his tenure at Boeing Aerospace. CIGS photovoltaics have traditionally lagged behind silicon in terms of research and investment despite the dramatically lower materials cost of CIGS. Dr. Stanbery’s discovery equips the photovoltaic industry with the in-depth understanding of CIGS that is necessary to bring the material to the mass market. One key prediction of the Stanbery Model has now been confirmed by research at the National Renewable Energy Laboratory (NREL). The model asserts that CIGS performance is attributed to a process called “spontaneous nanostructuring” by which the material in the CIGS absorber layer arranges itself at the atomic level for optimum photovoltaic efficiency. In other words, Dr. Stanbery’s model revealed that CIGS’ inherent physical properties make it one of nature’s best solar materials. He is now applying his fundamental understanding of CIGS thin-film to the commercialization of efficient, durable, CIGS photovoltaics incorporated into conventional building materials.
