Bifacial solar cells
OverviewHistory of the bifacial solar cellCurrent bifacial solar cellsBifacial solar cell performance parameters
A silicon solar cell was first patented in 1946 by Russell Ohl when working at Bell Labs and first publicly demonstrated at the same research institution by Calvin Fuller, Daryl Chapin, and Gerald Pearson in 1954; however, these first proposals were monofacial cells and not designed to have their rear face active. The first bifacial solar cell theoretically proposed is in a Japanese patent with a priority date 4 October 1960, by Hiroshi Mori, when working for the company Hayakawa Denki Kogyo Kabushiki Kaisha
