Bosch Solar Energy's Record Breaking Solar Cell

Bosch Solar Energy has unveiled a record-breaking large-format solar cell, which delivers an impressive 19.6 percent energy conversion rate.

The new 156 x 156mm PERC – Passive Emitter and Rear Cell – photovoltaic wafers were independently tested at the Fraunhofer Institute for Solar Energy Systems in Germany. The Institute confirmed the record had indeed been reached for monocrystalline solar cells with screen-printed metallisation in a large format.

Normally, silicon-based individual solar cells yield an average energy output of around 18 percent. When cells are place in an array, such as in a solar panel, further efficiency is lost..
