ELEG620: Solar Electric Systems University of Delaware, ECE Spring 2009S. BremnerMaking Solar CellsWe will look at some the differences that stand between solar cells that are research and commercial in particular the following features- materials that are used (semiconductor, quality of semiconductor)- processing used (complexity, number of steps)- designs
ELEG620: Solar Electric Systems University of Delaware, ECE Spring 2009S. BremnerResearch•Generally have more freedom in design since cost effectiveness is not main concern•However, the idea is to develop a high efficiency design and then try to implement as a commercially viable process sometimes•Because of the lack of restrictions in materials and processes the efficiencies reported for research devices are generally significantly higher than for commercial solar cells•Sizes tend to be small also, not always striaght forward to scale up
