This project continued the development of high efficiency silicon concentrator solar cells with the goal of achieving a 24% efficient module ready'' cell. This target was comfortably achieved with efficiencies as high as 25.2% at 125 suns concentration measured at Sandia National Laboratories. In outdoor testing at Sandia, cells of this type but of more modest performance resulted in lens/cell efficiency above 20% for the first time. Exciting results were obtained with a new cell structure, the PERC cell (passivated emitter and rear cell) which demonstrated an efficiency of 21.8% for a nonconcentrating cell and creditable performance out to 20 suns for concentrator cells. Progress was also reported for cells fabricated on n-type substrates and for plasma grooved, buried contact solar cells. 22 refs., 23 figs., 9 tabs.
