P-Type MWT solar cells: Current status and future expectations

This work gives a review on the present status of p-type metal wrap through (MWT) silicon solar cell development and presents future expectations. With novel materials and approaches, many critical issues that have been discussed as potential show stoppers in the past are now overcome. The MWT technology, especially when combined with rear surface passivation, has the potential to significantly decrease cost of ownership. According to our calculations, MWT-based modules show a cost advantage of 2 % against H-pattern approaches; cell conversion efficiency is expected to reach 21 to 22 % in the medium term.
