CSIR Pune organisation developed an artificial leaf to create fuel from sunlight

The researchers at the Council of Scientific and Industrial Research (CSIR)-National Chemical Laboratory in Pune have developed an artificial leaf that absorbs sunlight to generate hydrogen fuel from water, an advance that may provide clean energy for powering eco-friendly cars in the future.
The device consists of semiconductors stacked in a manner to simulate the natural leaf system. When visible light strikes the semiconductors, electrons move in one direction, producing electric current. The current almost instantaneously splits water into hydrogen – which researchers believe is one of the cleanest forms of fuel as its main byproduct is water.
