Why is alkaline texturing important in solar cells?
Texturing the surface of crystalline silicon wafers is a very important step in the production of high-efficiency solar cells. Alkaline texturing creates pyramids on the silicon surface, lowering surface reflectivity and improving light trapping in solar cells.
Can laser texture based solar cells be made on mc-Si wafers?
There were similar efforts for the fabrication of laser texture based solar cells on mc-Si wafers later as well , , . However, mostly on smaller area mc-Si samples because of the lower speed of laser texturing. Laser texturing process is expensive, complex, and time-consuming compared to existing chemical texturing processes.
