Scientists are always pushing the boundaries of solar cell efficiency – how much of the available sunshine gets turned into electricity – and a new approach to the technology has resulted in an astonishingly high 130 percent ' quantum yield '. It's important to note that this is a quantum-level energy return, so we're not talking about a solar panel converting sunlight into electricity at a 130 percent rate. However, the breakthrough is an efficiency improvement in terms of how often a specific
