Further efficiency improvements of the n-type MWT Si solar cells using industrial processes
The use of n-type silicon allows for high efficiencies: efficiencies up to 20% have been reported for industrial cells.MWT cells allow even higher cell efficiency due to reduced front metal coverage.The efficiency of MWT cells produced by industrial processes reproducibly exceeds the efficiency of front contact cells based on the same technology by 0.2-0.3%.Another advantage of back-contact MWT modules is the reduced cell to module fill factor losses.In a direct comparison,a 60 cell MWT module,based on integrated back foil,produced 3% more power compared to the tabbed module.Finally,simple process optimisations were tested to further improve the n-type MWT cell and module efficiency.A module made using MWT cells of 19.6% average efficiency resulted in a power output of 279 W.
