Als je 1 cell kunt opdampen dan kun je er miljoenen opdampen
CIGS photovoltaic cells, or Copper Inidium Germanium Selenium mixtures can be designed for specific band gaps which determines what types of light they can convert into electricity. EMPA in Switzerland reports 18,7% efficiency with their CuIn1-xGaxSe2 cells. The trick apparently lies in the thickness of the Gallium layer, a parameter that can simply be varied. This means thin film flexible cells with output better than current Silicon cells (14%-17%). The support materials for these cells will make them cheaper to produce, easier to transport, more productive and less energy intensive. CIGS are usually overinvested and keep failing for mysterious reasons, probably because the energy sector likes their turnover on the energy intensive production of solar grade silicon and panels. Let’s hope this gets out of the lab soon and is made available at a margin that is not exploitative for a change.
