This weeks BBC Science Cafe sees Adam Walton exploring the latest technology to harvest the power of the sun, including the search for more sustainable materials to be used in the manufacture of solar cells.

Adam visited the OpTIC Centre in St Asaph, home to Swansea University’s Centre for Solar Energy Research, where he chats to Professor Stuart Irvine about the SPARC II project –  a collaboration between Swansea, Bangor and Aberystwyth universities, which provides five years funding aimed at addressing the key challenges of developing next generation solar photovoltaic technology.
