Fraunhofer ISE has developed a new software tool that determines the cell-to-module (CTM) effects that occur when solar cells are integrated into a module. The SmartCalc.CTM software enables manufacturers of PV modules and materials to optimize the assembly and material combination in a PV module before fabricating a prototype.
In this week's Movers & Shakers, PV Tech covers the controversy surrounding the sudden exit of Brian Molefe from South African utility Eskom after scandal accusations, and reports on whether this could emerge as an opportunity for the country's embattled renewables procurement programme. We also report on First Solar slashing jobs after it rescinded on its former plans to migrate its series five module and other happenings from the US, Europe and China.
Fraunhofer ISE said it was spearheading the largest research project (APV-Resola) in Germany to establish whether the dual use of land for the production of electricity using photovoltaic (PV) modules can be commercially viable with a range of crops grown on the same land.
This paper introduces and explains a simulation-assisted approach for determining and ranking the most influential causes of variations in experimentally obtained solar cell efficiencies, using the example of an industrially feasible multicrystalline silicon (mc-Si) passivated emitter and rear cell (PERC) process. The approach presented is especially helpful for ramping up PERC production; however, since it is basically transferable to any solar cell concept, it can also be applied to optimize established production lines.
