As part of the Energy Strategy 2050, the electricity gap resulting from the phase-out of nuclear energy is primarily compensated with PV modules. The Energy Strategy 2050 plans the expansion of photovoltaics to 12 TWh in 2050. This could rise to 24 TWh due to the elimination of deep geothermal energy (4TWh) and the replacement of cars with combustion engines by electric vehicles (approx. 8TWh) i. Based on the current PV market, a huge number of installed PV modules will be seen 2050. These modules can be made up of different technologies such as c-Si, thin-film modules such as Cd/Te, CIS or CIGS. Assuming a service life of 25-40 yearsii, all these modules must be dismantled and disposed of again. Even for PV modules alone the quantities of material that will be disposed of in Switzerland and thus the recycled material flows are considerable. Forward-looking planning of the products employed, and their recycling is important for users and installers. This is where the joint research efforts of SENS eRecycling and the Bern University of Applied Sciences BFH come in.
