Identifying critical pathways to high performance PV

The High-Performance Photovoltaic (HiPerf PV) Project was initiated by the US Department of Energy to substantially increase the viability of photovoltaics (PV) for cost-competitive applications so that PV can contribute significantly to our energy supply and our environment in the 21st century. To accomplish this, the NCPV directs in-house and subcontracted research in high-performance polycrystalline thin-film and multijunction concentrator devices. Details of the subcontractor and in-house progress are described toward identifying critical pathways of 25% polycrystalline thin-film tandem cells and developing multijunction concentrator modules to 33%.
