A newly developed material for the electron contact improves the efficiency of single perovskite solar cells and ...

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 ...

Solar cells' efficiency and lifespan are often determined by what happens at interfaces—the microscopic boundaries where ...

Researchers in China have developed an inverted perovskite solar cell approaching the 27% efficiency threshold. The device incorporates a specially designed self-assembled monolayer that passivates ...

Perovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely ...

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, ...

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.

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 ...

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 ...
