Title: Hartmut Presting: Innovator in Solar Technology
Introduction
Hartmut Presting is a notable inventor based in Blaustein, Germany. He has made significant contributions to the field of solar technology, holding a total of 4 patents. His innovative work focuses on enhancing the efficiency of solar cells and developing advanced photodetectors.
Latest Patents
One of his latest patents is a silicon-germanium solar cell that boasts high power efficiency. This invention features a silicon-germanium thin-film solar cell with a quantum well structure as an active base layer within the space-charge region of the silicon p-n diode junction. The quantum well structure is composed of a sequence of silicon and germanium layers, resulting in a highly absorbent base layer in the silicon solar cell.
Another significant patent is the voltage-controlled wavelength-selective photodetector. This device includes a double diode comprising a counter-polarized Si-Schottky diode and a SiGe PIN diode. The short-wave portion of the light entering the detector generates electron-hole pairs in the Si-Schottky diode, while the longer-wave portion passes through the substrate and is absorbed in the epitaxially deposited SiGe superlattice or the quantum well diode. The photocurrents of both detectors flow in physically opposite directions, resulting in a wavelength-dependent operational sign of the photocurrent. This technology can be utilized in applications for decoding signals by transforming light signals into electrical output signals, effectively filtering out noise components and enhancing the signal-to-noise ratio.
