AI Customer ServiceAs one of the critical raw materials the use of it (mainly driven by solar cells) is a major contributor to mineral resource depletion. Today, Germanium is used as a growth template for certain solar cells. While the thickness of the Germanium on a solar cell level is extremely thin, around 140μm, actually only 10-20μm are actively being used.
The realm of solar cells has recognized germanium substrates as potent absorber material, exhibiting high efficiency. A typical thickness of 500 nanometers in the said substrates is known to significantly amplify the photocurrent generated by a single junction solar cell.
The incorporation of germanium breathes new life into solar cell technology, offering several edges over traditional silicon-based photovoltaic systems. The conversion efficiency – a key yardstick in renewable energy production – can witness marked improvement with germanium-centric solar power frameworks.
