Science commentator Dr Allan Blackman joins Lynn to look at new research into how the sun's energy can be converted into electricity more efficiently. At the moment silicon solar cells can only manage a maximum of 33 % conversion, so the hunt is on for more efficient materials. And April 20 marks a big day for science: in 1862 Louis Pasteur demonstrates the process we've come to know as pasteurisation and in 1902 Marie and Pierre Curie successfully isolate radioactive radium salts.
