Efficient and cost-effective: sustainable solar cells for the future

 

Application relevant validation of c-Si (crystalline silicon) based tandem solar cell processes with 30 % efficiency target

Crystalline silicon wafer solar cells have been dominating the photovoltaic market so far due to the availability and stability of c-Si and the decades of Si technology development. However, without new ways to improve the conversion efficiencies further significant cost reductions will be difficult and the c-Si technology will not be able to maintain its dominant role. In particular, with respect to conversion efficiency Si solar cells today already are close to their technologically limit. Compared to that until today III-V multijunction solar cells did already show that the current generation can almost be doubled at the same solar cell size.
