Photoelectric cell e.g. anti-stokes enhanced-cell (ASEC) has layer sequence to increase initial energy of semiconductor layer and to direct photons with output power towards semiconductor layer

摘要

The photoelectric cell (100) has a layer sequence (110) that is configured for up-converting photon energy. A semiconductor layer (120) is located on the layer sequence. The semiconductor layer is configured to absorb incident photons (101) with an energy (Eph0) corresponding to the energy band gap (Eg) of the semiconductor layer. The layer sequence is adapted to increase the initial energy (Eph1) of the semiconductor layer. The layer sequence is configured to direct the photons with the output power (Eph2) towards the semiconductor layer.
