Solar PV efficiency - new breakthrough!

Solar photovoltaic panels are currently limited to a maximum efficiency of about 30%, and in practice only actually achieve about 20% to 23% efficiency. Now a team in Cambridge has developed a film that can amplify the number of photons that the panel can use, with a potential increase in efficiency to as much as 35%. So how do they do that?
