Researchers Make Case for Gallium-doped p-type Heterojunction Solar Cells Updated On Mon, Jul 26th, 2021 by Saurenergy Researchers of an Austrian-Russian research group have come out with a technique to make Silicon Heterojunction Solar Cells based on P-type wafers more efficient and stable with Gallium-doping. These p-type, Gallium-doped wafers have proved to be 22.6% efficient, more stable, and cheaper than the usual n-type Phosphorus-doped Czochralski–grown silicon (Cz–Si) wafers. The scientists of the […] Read more
