Chinese researchers achieved 32.22% certified steady-state conversion efficiency in a triple-junction solar cell using lower-cost materials.

Chinese researchers reported a certified steady-state photoelectric conversion efficiency of 32.22% for a triple-junction solar cell. The result was published in the journal Nature on Aug. 17.

Triple-junction solar cells are used in applications including satellites and space probes. The reported research focused on using lower-cost materials to support potential terrestrial applications.

The 32.22% figure is a certified steady-state conversion-efficiency measurement, not a power-capacity or production-volume figure. The supplied source does not identify a manufacturing cost, module size, production yield, degradation rate, commercial supplier, or deployment schedule.
