Abstract
A silicon substrate is chemically etched and intercalated with boron and on one side only with phosphorus, before being metallised using an aluminum-free silkscreen printing silver paste. A method for making silicon solar cells comprises: (i) reducing the thickness of the starting substrate (blank) by chemically etching the silicon (ii) intercalating with boron (iii) masking one side of the substrate and chemically etching the opposite side (iv) intercalating with phosphorus and (v) metallising both sides of the substrate with an aluminum-free silver paste by silkscreen printing.
