Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. The materials physics shows that this is possible, the same semiconductor ...

ZnSc 2 S 4 exhibits a direct bandgap and can emit light from orange to blue. Its composition can be chemically tuned to switch between n-type and p-type conduction over nine orders of magnitude, ...

An international team of researchers has uncovered the hidden mechanism that limits the performance ...

In solar cells, it optimizes light absorption. "This increases the light-harvesting efficiency, crucial for increasing the power conversion efficiency of solar cells," says Pu. Pu's team plan to ...

An international team led by the U.S. National Renewable Energy Laboratory (NREL) has used ionic salt for the electron transport layer of a perovskite solar cell to improve device stability and ...

The research advanced the durability of perovskite solar cells without compromising their exceptional efficiency, moving closer to a practical, low-cost alternative to silicon-based photovoltaics.

Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it ...

The 1cm² cells, pictured, achieved a record-breaking 27.06% power conversion efficiency. Image: University of Sydney. Scientists from the University of Sydney have created what they claim is the ...
