High-Mobility Transparent Conductive Electrodes
Doped transparent oxide front contacts paired with optimised metal grid geometry cut parasitic absorption and series resistance, letting more current and voltage out of tandem and thin-film solar cells without altering the absorber stack.
Developed mainly in: ChinaImpacting: North America, Europe, India and China
A Chinese academic consortium led by Southwest Petroleum University, with the Chinese Academy of Sciences, Shanghai Normal, Chongqing University and UCAS, reworked the front electrode of perovskite-silicon tandem cells, swapping indium zinc oxide for tungsten-doped indium oxide and optimising grid geometry (~50 µm lines, 2.5 mm pitch). Result: 33.06% champion and 32.28% certified efficiency, with…
