Current photovoltaic-cell technology, typically a semiconductor-based system, is expensive, not very efficient, and only does instant conversions from sunlight to electricity. But an artificial photosynthesis system or a photo-electrochemical cell that mimics what happens in plants could potentially… »

The technology could be… »
