Plus MAT AG Information

Today, the levelized cost of energy (LCOE) and energy returned on energy invested (ERoEI) persist as the key metrics in determining the market acceptance of photovoltaics (PV) as a competitive grid-tied energy provider. In every watt of PV electricity from modules, the cost of PV-grade Silicon (Si) accounts for about 20%. However, at least 40% of Si is lost at present during wafer production process. Plus MAT AG (+MAT), a Swiss high-tech start-up, is commercializing a patented cost-effective and innovative system, including equipment and process, to recover the lost Si from PV sawing process for direct re-application in the production line. With the implementation of the Si recovery system developed by +MAT, 50% to 90% of the presently lost Si can be recovered, leading to 5% or more saving in the production cost at PV module level.
