Is that true... You get almost 2 times the power output with GaAs cells then conventional solar cells made from silicone?
- tinco 11y agoYes[0]. Apparently the records lie at 41% for GaAs and 27% for silicon[1] so they're being a little bit loose with the stats, 20% for silicon is consumer grade panel level. 0] https://en.wikipedia.org/wiki/Gallium_arsenide#Solar_cells_and_detectors https://en.wikipedia.org/wiki/Gallium_arsenide#Solar_cells_a... 1] http://www.pveducation.org/pvcdrom/appendices/solar-cell-efficiency-results2 http://www.pveducation.org/pvcdrom/appendices/solar-cell-eff...
