Title:
バックコンタクト光電池セルの製造方法およびそのような方法によって製造されたバックコンタクト光電池セル
Document Type and Number:
Japanese Patent JP2011503907
Kind Code:
A
Abstract:
A method of manufacturing a photovoltaic cell, includes: providing a semiconductor substrate of a first conductivity type; creating at least one via between a front side and a back side of the semiconductor substrate; applying on the backside a front side contacting metal paste over the at least one via, the front side contacting metal paste including a first contacting metal; annealing the semiconductor substrate so as to melt the first contacting metal, and during annealing, creating at least on the walls of the at least one via an alloy of the first contacting metal and the semiconductor substrate material.
