Neo Solar Power announced that is has created a 21.1% efficient solar cell with passivated emitter rear contact (PERC) technology. The maximum efficiency was certified by the Taiwan Industrial Technology Research Institute (ITRI).
neosolarpowerThe p-type mono record was set by Trina Solar at 21.4% last November, so Neo Solar is close with its “Black 21” cell builds. Neo Solar also has cells named Black 19 and Black 20.
A passivation layer is added at the rear side of the cell in PERC technology to increase conversion efficiency. Energy conversion rates of about 20.5% are typical for PERC monocrystalline solar cells. The efficiencies have been good, but costs have also been higher. Some more intriguing applications for these cells are for solar cars and space.
