Researchers Enhance Efficiency of Ultrathin CIGSe Solar Cells Using Nanoparticles

CIGSe solar cells are made of a thin chalcopyrite layer consisting of Copper, Indium, Gallium and Selenium and can reach high efficiencies. Since Indium is becoming scarce and expensive, it is interesting to reduce the active CIGSe layer, which however decreases the efficiency quite strongly.

Square Optical Resonators Support High Q Whispering-Gallery Modes for Realizing Unidirectional Microlasers

Totally internal confined whispering-gallery modes can have high Q factors in wavelength scale optical microresonators, such as microspheres and two-dimensional microdisk resonators. Square optical resonators can also support high Q whispering-gallery modes, suitable to realize unidirectional microlasers.
