Neo Solar Power Announces 21.1% Efficient Mono-PERC Solar Cell

By Jake Richardson via Clean Technica.

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).

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.
