What are hot solar cells

Argumentation: hot air in the solar lobby

According to a Forsa survey, the majority of citizens are willing to spend one euro a month on promoting photovoltaics - but no more. According to Gabriel, the cost is one euro per person per month - but the Ministry of the Environment only assumes private electricity consumption. Increased costs for goods and services as well as additional government electricity costs are forgotten. If these cost factors are taken into account, the solar subsidies are already well above the pain threshold. By the way: two years ago the majority stated that they were willing to pay two euros or more - so acceptance is dwindling. World market leadership: This only applies to installation, but not to production, which is more important as an economic factor. There are many solar companies in Germany, including Q-Cells in Thalheim, Conergy in Hamburg, Solarworld in Bonn, Johanna Solar Technoloy in Brandenburg or large-scale settlements such as the Solar Valley in Saxony-Anhalt. But most of the solar cells come from Asia: 28 percent from China, 22 percent from Japan. Germany ranks third with a global market share of 21 percent. The big players are abroad: The Norwegian REC is building the world's largest solar factory in Singapore. First Solar from the USA, the front runner in thin-film modules, has a plant in Frankfurt / Oder, but this only contributes 20 percent to production, the next three factories are being built in Malaysia. Sharp from Japan is likely to operate the world's largest factory in the thin-film segment in 2010. Climate friendliness: In purely mathematical terms, the generation of two billion kilowatts of solar power saved 1.1 billion tons of CO2 in 2006. But the CO2 avoidance costs are very high at around 945 euros per ton. It would be cheaper to leave the avoidance of CO2 to emissions trading. The price for emission certificates is 30 euros per ton.
