With solar cell prices plummeting due to overcapacity, the push for cost reduction has intensified. Tandem solar cells using perovskite layers promise efficiency gains from 26% to 34%, but measuring these cells accurately requires overcoming hysteresis effects. XENON simulators struggle with this due to their short flash durations, while LED simulators offer extended, stable flashes and precise spectral matching. MBJ Solutions provides advanced LED based simulators that meet these demands effectively.
Manufacturers of solar cells and modules are experiencing an unprecedented drop in prices due to excessive overcapacity. As a result, there is a strong push to lower the cost per unit of power. While incremental improvements have been achieved with PERC and TOPCon technologies, a more significant advancement is necessary. Tandem solar cells that use a perovskite layer on a silicon wafer offer the potential to boost efficiency from the current 26% to 34% with relatively minimal effort.
