  • The High-Performance Photovoltaic (HiPerf PV) Project was initiated by the U.S. 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. The HiPerf PV Project aims at exploring the ultimate performance limits of existing PV technologies, approximately doubling their sunlight-to-electricity conversion efficiencies during its course. This work includes bringing thin-film cells and modules toward 25% and 20% efficiencies, respectively, and developing multijunction concentrator cells and modules able to convert more than one-third of the sun's energy to electricity (i.e., 33% efficiency). This papermore » will address recent accomplishments of the NREL in-house research effort involving polycrystalline thin-film tandems, as well as the research efforts under way in the subcontracted area.« less
  • This paper describes an innovative design for a nominal 20 kW, integrated, high-concentration (260X) photovoltaic (IHCPV) system which has been developed for cost-effective, utility-scale bulk power generation. This technology recently set a new world record for efficiency: 20.3% under STC (18.5%, > 20 kW at PVUSA operating conditions). High-concentration PV systems offer several advantages for low cost power generation: (1) cost reduction through the optimum utilization of silicon, (2) higher conversion cell (hence system) efficiency at concentration vs. one-sun, and (3) inherently higher capacity factor in high direct normal insolation areas because of its built-in tracking. Previously little progress hasmore » been made in deploying HCPV for large-scale electricity generation because of: (1) the lack of stable, high performance, high-concentration solar cell, and (2) the high cost associated with the PV modules, structure, tracking system, and ancillary equipment. With the arrival of a stable high performance cell developed by AMONIX, high-concentration PV systems can now be realized. A novel integrated system concept greatly reduces the costs associated with system hardware and labor by: (1) integrating the load bearing structure and the Fresnel lens/receiver plate elements eliminating the need for separate modules, and (2) use of a manufacturing-worthy receiver plate which makes use of circuit-board construction techniques. A full-scale 20 kilowatt IHCPV system has been deployed, and test results which validate the system design are reported. The IHCPV system development is complete and only volume production, not technical breakthroughs, is needed to meet the cost goals of < $2.00/watt at multi-megawatt levels.« less
