Even if germanium were as abundant and as easy to produce as silicon, it would not be used for solar cells (in the same way as silicon is used, namely as single-junction cell) because of its lower
Si is among the most abundant materials on Earth and widely used for processors as well. There are very few other materials that can even theoretically compete with that. Germanium and GaAs won''t be ever able to. Organic solar cells were promising due to low fabrication cost (just ask bacteria or whatever to make your solar cells), but failed.
The germanium-based solar cells convert up to twice as much light into electricity as their silicon-based counterparts. Since germanium is more resistant to damaging cosmic radiation than silicon, the solar cells'' lifespan can be extended from 15 to 20 years.
Solar cells generally require semi-conductors for their construction.Silicon and Germanium are semi-conductors and Gallium when mixed with other impurities can act as semi-conductor but Platinum is not a semiconductor and Platinum being a metal is a good conductor can not be used as semi-conductor and more over platinum is very expensive to get.
This project worked on two different approaches to increase the effective use of germanium in multi-junction solar cells. The first work package studied how germanium can be recycled from
As 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.
Organic–inorganic metal halide perovskites are widely used in solar cells, but the toxic metal Pb 2 + is still a necessary element to ensure excellent photovoltaic properties, so it is urgent to accomplish the conversion to low toxic perovskite solar cells. In this work, by introducing MAGeI 3 to form a double absorber layer structure with MAPbI 3, a novel germanium–lead
Germanium in Solar Panels. Multi-Junction Solar Cells: Germanium is used in multi-junction solar cells that are more efficient than silicon-based cells.

The effect of temperature on the performance parameters [short-circuit current density (J SC), open-circuit voltage (V OC), fill factor (FF), and conversion efficiency (η)] of stand-alone germanium (Ge) solar cells has been theoretically investigated.Although J SC increased with increasing temperature, η decreased due to a decrease in V OC and the associated

Bamberg says germanium-based solar cells are used on most spacecraft because they are more efficient and lighter than silicon-based solar cells. By making it more attractive economically to use efficient germanium solar cells on rooftops, the weight and size of solar panels can be reduced "so it doesn''t bother you aesthetically," he adds.

With the emergence of the third generation photovoltaic technology, perovskite solar cells (PSCs) have outperformed short-term predictions for power conversion efficiency (PCE) [7] due to their impressive rise in device efficiency, which went from 3.8% in 2009 to 25.5% recently and attracted much interest from the solar cell research community [8], [9].
An optimum can be seen around a layer thickness of 30 nm; of course this is only the case for application of the stand-alone cell under the solar spectrum. If the germanium is used as a bottom cell in a mechanically stacked solar cell underneath a GaAs cell, the spectrum reaching the germanium will have no photons with wavelengths less than 900
Reducing environmental impact is a key challenge for perovskite optoelectronics, as most high-performance devices are based on potentially toxic lead-halide perovskites. For photovoltaic solar
Germanium is an important material for today''s highest efficiency solar cells with three np-junctions based on GaInP, GaInAs and Ge. The Ge subcell in these structures consists of a 100–300 nm thin diffused n-type emitter passivated with GaAs or GaInP and a 150 μm thick base layer which is not passivated. Therefore, the current generation of the Ge subcell mainly
It is a rare and an expensive material and used in some of the highest efficiency solar cells, often used in the space industry where the cost of the cells is nothing compared to the overall project cost.
