Resumen
At present time solar cells made of silicon based on upgraded metallurgical routes (umg-Si) are entering the photovoltaic market and becoming a real option to the standard polysilicon-based (mc-Si) devices. While a lot of research at wafer and cell level has been carried out so far, there is little experience in real operation conditions of PV modules based-on umg-Si feedstock and only a few studies have been published. In this work a comparative study between typical polysilicon and umg-Si based modules, manufactured following exactly the same wafer-to-module procedures and evaluated in outdoor conditions, is presented. The results after one full year of exposition to outdoor conditions show a very similar behavior that leads to a very close energy production for both types of modules. With a lower cost and similar performance, modules made from umg silicon feedstock a ra more economic option and could play an important role in the photovoltaic market.
