Abstract
This master thesis investigates the properties of high performance multicrystalline silicon, and the production line of black multicrystalline silicon

solar cells with PERC architecture. Possible solutions to achieve higher

efficiency were explored, and different steps in the production route were

examined.

Three steps of the production chain were in focus. Decreasing the polishing

time by 70 seconds proved to enhance efficiency. Optimizing the emitter

doping process by varying parameters in the deposition step, achieved a

more uniform doping distribution across the wafers, and improved overall

doping homogeneity by reducing standard deviation by 24%.

Further, the rear passivation step was investigated, and it was found that

by increasing the thickness of the Al2O3-layer from 14 to 24 nm, efficiency

was improved. The final experiments combined the best result in each of the

other steps, and optimized parameters were implemented in the production

chain for an overall optimization. A champion efficiency above 20% was

achieved, which is 0.23% higher than average baseline efficiency for all

PERC wafers investigated in this thesis.
