Scientists invent topological-cavity surface-emitting laser

Semiconductor lasers are the most widely used lasers due to their compact size, high efficiency, low cost and wide spectra. But they suffer low output power and low beam quality—two specifications difficult to improve simultaneously. ...

Solar beats nuclear at many potential settlement sites on Mars

The high efficiency, light weight and flexibility of the latest solar cell technology means photovoltaics could provide all the power needed for an extended mission to Mars, or even a permanent settlement there, according ...

Record efficiencies in thin film photovoltaic cells

Silicon solar cells have proven to be a top photovoltaic technology, as they use earth abundant raw materials (i.e. Si) and perform with high efficiency. However, they are based on thick, rigid and heavy wafers and can therefore ...

Researchers fabricate large-area sky-blue PeLEDs

The research group led by Prof. Xiao Zhengguo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences prepared large-area and efficient sky-blue perovskite light-emitting diodes (PeLEDs) ...
