Photovoltaisches Halbleiterbauelement zur Konversion von Strahlungsleistung in elektrische Leistung, Verfahren zu dessen Herstellung und dessen Verwendung

The invention relates to a photovoltaic semiconductor component for converting monochromatic radiation power into electric power, comprising at least one front-side sub-cell which faces the radiation incident on the semiconductor component and a rear-side sub-cell which is made of interconnected semiconductor layers. The materials of the semiconductor layers and/or the layer thicknesses thereof are selected such that at least one sub-cell exhibits an increased photon absorption compared to the other sub-cells. The invention likewise relates to a method for producing said photovoltaic semiconductor components. The photovoltaic components are used as radiation receivers in optical power transmission for example for monitoring high-voltage lines, passive optical networks, the supply of energy to and in active implants, disturbance-free electromagnetic field measurement, lightning-protected monitoring of wind turbines, explosion-proof sensor systems in airplane tanks, wireless power transmission, galvanically isolated power supply for sensor systems in high-voltage environments, wireless charging of consumer electronics, and the supply of power to underwater observatories
