Abstract :
A wafer-scale-integrated (WSI) module of back-side contact (BSC) solar cells has been developed for central receiver or concentrating dish applications. Two parallel strings of five series-connected BSC cells on a single 4 in silicon wafer, mounted on a cold plate, form a 6 cm×6 cm monolithic module producing more than 140 W under 20 W/cm 2 at operating temperature. The best measured efficiency is 20.8% at around 7 W/cm2 and at 39°C cell temperature. At 25°C, the monolithic module is 22% efficient at 5.8 W/cm2
