DThis composition, without it, there is no solar energy, looks inconspicuous, like silver glittering gravel.Polycrystalline SiliconThis metal is called polysilicon for short. It is the most important raw material for the production of photovoltaic modules, and German homeowners fix it on the roof under government subsidies. In a large solar park, the module covers the entire mountain range.
“Solar energy is the new king of power generation,” declared Fatih Birol, Director-General of the International Energy Agency (International Energy Agency), in Paris. According to calculations by the International Energy Agency, solar energy is the cheapest in human history, much cheaper than electricity from coal and natural gas power plants. In the future, photovoltaics will become the world’s most important climate-friendly source of electricity and the new king. The Berlin government has set a goal of doubling German solar production capacity by 2030.
