The demonstrated device, according to the academics, is built with interfaces between the active cell layers that improve the top cell carrier collection. The cell was built with texturing and a ...

US scientists have made light-tracking, three-junction tandem PV cells with an active area of 650 × 650 square micrometers. They are based on indium gallium phosphide, gallium arsenide, and indium ...

A focus-stacked macro photograph of a fabricated gallium phosphide photonic chip featuring multiple spiral waveguides and other test structures. The chip width is just 0.55 cm across. Due to the high ...

The interaction between single molecules and a gap nanoantenna made of gallium phosphide is measured thanks to single-molecule fluorescence lifetime imaging microscopy (smFLIM). This technique ...
