Thin-Film Solar Cell Approaches Efficiency Record
A Copper Zinc Tin Selenide (CZTSe) solar cell technology has achieved an efficiency of 9.7% and an open-circuit voltage of 0.41 volts, a bit less than the 0.5 volts that most silicon-based solar cells achieve. (Solar cells are generally connected in series, which multiplies their voltage by the number of cells in the series connection.)…
