Measured performance of ENTECH's crossed lens photovoltaic concentrator
Over the past several years, ENTECH has been developing a patented, optical concentrator concept called the crossed lens concentrator. Detailed design studies and analytical performance analyses conducted on this optical concept have resulted in the development of two types of photovoltaic concentrator modules: a 160X crossed lens module which uses advanced silicon cells and a 500X crossed lens module which uses gallium arsenide (GaAs) cells. An innovative prismatic cell cover has been developed which completely eliminates gridline obscuration losses on the photovoltaic cell. A cell cover has been fabricated and tested which will allow 55% of the cell's active area to be obscured by gridlines. Designs for the 160X silicon cell and the 500X GaAs cell have been generated and are currently being fabricated by Solarex and ASEC, respectively, for use with the new cell cover. Both module designs are described and recent test results are presented. 4 refs.
