Photovoltaic effect in few-layer black phosphorus PN junctions defined by local electrostatic gating
In the past few years, the research effort on 2D materials has rapidly increased, driven by the great variety of layered materials and their exceptional properties when reduced to a few atomic layers ...
Scientists at Germany's Fraunhofer Institute for Solar Energy Systems ISE have demonstrated a triple-junction solar cell with a perovskite-perovskite-silicon subcell configuration. They said the cell ...
The feature size of silicon-based transistors is approaching the theoretical limit, which puts forward higher requirements for the “atomic level manufacturing” of semiconductors. The basic idea of ...
The open-circuit voltages of mature single-junction photovoltaic devices are lower than the bandgap energy of the absorber, typically by a gap of 400 mV. For CdTe, which has a bandgap of 1.5 eV, the ...
