Ultra-thin design boosts durability of high-performance, low-cost solar cells

Dec. 9, 2021

Using materials known as perovskites, Princeton researchers helped develop ultra-thin material layers, only a few nanometers thick, shown above in vertically stacked sheets. One of these ultra-thin layers can cap a solar cell's underlying absorption layers, protecting them from stress and moving electronic charge at rates that far outstrip previous designs. This innovation can dramatically improve perovskite solar cell durability.
