Figure 2: Comparison of normalized short-circuit current generated by a solar cell for light transmitted through AR coated and uncoated glass wafers over a range of light incident angles. At normal incidence, light transmitted through AR coated glass yields 5% more current than light transmitted through uncoated glass. At off-angles, the AR coated glass yields up to 20% more current than light transmitted through uncoated glass. 7KH VKRUWFLUFXLW FXUUHQW DQDO\VLV LQGLFDWHV WKDW WKH OLJKW WUDQVPLWWHG WKURXJK WKH $5 FRDWHG JODVV ZDIHU \LHOGV XS WR KLJKHU VKRUWFLUFXLW FXUUHQW DW RIIDQJOH OLJKW LQFLGHQFH FRPSDUHGWRWKHOLJKWWUDQVPLWWHGWKURXJKWKHXQFRDWHGJODVVZDIHU)LJXUHFRPSDUHVWKHVKRUW FLUFXLWFXUUHQWREVHUYHGXQGHUYDULRXVLOOXPLQDWLRQFRQGLWLRQVDQGOLJKWLQFLGHQWDQJOHV,QWKH
