Non-silicon solar power – cheaper but less efficient?
29/11/2007 Guardian Research aims to make much cheaper non-siliocon solar cells but efficency is much less. The Carbon Trust is funding research at the Cavendish lab in Cambridge aimed at producing solar cells which are non-silicon. Potentially these can be very cheap and paper thin but the efficiency may be only 5% compared with 40% for silicon cells. Article by Michael Pollitt in the TechnologyGuardian.
