PHOTOVOLTAIC CELL FOR THE MWT TYPE FOR DEDICATED CONDUCTIVE BACKSHEET

摘要

Back-contact photovoltaic cell (10) of crystalline silicon of the Metal Wrap Through or MWT type, for a dedicated conductive backsheet (20); said cell (10) having holes for the crossing of the collected electrons at the front and punctiform back contacts for the charges of opposite sign, N holes (102) and P points (104) respectively, arranged according to a configuration of the contacts which is also advantageous for the purpose of automated production and for the association with a conductive backsheet (20) integrating one single conductive layer (200) intended to connect by strings the N holes and P points of all the cells, completing the electrical circuitry of the whole panel. The cell (10) comprises 24 N holes (102) and 15 P points (104), respectively aligned in 4 N rows (103) of 6 holes each and in 3 P rows (105) of 5 points each, with particular centre-to-centre distances.
