6 FAQs about [Solar power generation material silicon germanium]
Can germanium be used as a substrate for solar cells?
Germanium has long been a popular material for integrated circuits. Outside the core area of electronic devices, an EU-funded project is showing its great potential as a substrate to lead next-generation multi-junction solar cells.
Where can solar-grade Si be produced?
Most of the solar-grade Si currently on the market is being produced from MG-Si as a starting material. Silicon production is energy intensive; therefore, sites with abundant, clean, and inexpensive hydroelectric power are preferred locations for future Si plants.
How did Germany develop a solar industry?
These include research and development funding and development policies, which led to the development of a solar industry. This development was in particular driven by guaranteed feed-in tariffs which were first implemented in Germany in 2000.
Is germanium a safe material?
Germanium is a metalloid with atomic number 32 and atomic weight of 72.63. It belongs to chemical group 14 in the periodic table. Relative to most other PV materials (e.g., As and Cd), Ge is considered safe.
Why do solar-grade polysilicon emit more carbon?
The higher material requirements of solar, wind, hydro, and geothermal generation (Figure 4), result in higher material-associated carbon emissions for these technologies (Figure 3), due to greater steel and concrete needs and the high carbon intensity of solar-grade polysilicon.
What materials are used in solar panels?
Overall, crystalline Si, CdTe technology, and CIGS account for 92%, 5%, and 2% of the solar panel market, respectively. All other materials, including those used in the third generation of PV panels (based on organic hybrid, dye-sensitized, and concentrator PV (CPV) technologies) account for 1% of the solar panel market (Chowdhury et al., 2020 ).
