....... "Overall, our new solar cells increase power generated by 30 per cent," said Dr Kylie Catchpole, co-author of the study. As part of the process, UNSW researchers, led by Phd student Supriya Pillai, place a thin film (about 10 nanometres thick) of silver onto a solar cell and heat it to 200C. The film breaks into tiny 100-nanometre "islands" of silver and raises its light-trapping efficiency. With this the team can move from thick expensive silicon "wafers" to cheaper "thin film" cells with less silicon. "Most thin-film solar cells are between eight and 10 per cent efficient, but the new technique could increase efficiency to between 13 and 15 per cent," Dr Catchpole said. more.... Message 23512789
