Silicon point contact concentrator solar cells
Abstract
Experimental results are presented for thin high resistivity concentrator silicon solar cells which use a back-side point-contact geometry. Cells of 130 and 233 micron thickness were fabricated and characterized. The thin cells were found to have efficiencies greater than 22 percent for incident solar intensities of 3 to 30 W/sq cm. Efficiency peaked at 23 percent at 11 W/sq cm measured at 22-25 C. Strategies for obtaining higher efficiencies with this solar cell design are discussed.
