A silicon was first patented in 1946 by when working at and first publicly demonstrated at the same research institution by , , and 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
[pdf] The number of solar modules shipped from China to Africa increased by 60% in the 12 months to June 2025, according to new analysis from Ember. The think tank recorded 15 GW of Chinese PV imports for the period, up from 9.3 GW the previous year.

CdTe PV is the cheapest example of PV technologies and prices are about 16¢/kWh with US Southwest sunlight. PV solar cells based on CdTe represent the largest segment of commercial thin-film module production worldwide. Recent improvements have matched the efficiency of multicrystalline silicon while maintaining cost leadership.
