All over the world researchers are investigating solar cells which imitate plant photosynthesis, using sunlight and water to create synthetic fuels such as hydrogen. Empa researchers have developed such a photoelectrochemical cell, recreating a moth's eye to drastically increase its light collecting efficiency. The cell is made of cheap raw materials - iron and tungsten oxide.

Scientists have discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thought it could help them harvest energy from the sun much more efficiently. Working out its role in a living organism could lead to technological advances, such as better organic solar cells and quantum-based electronic devices.

By combining the advantages of two well-established spectroscopy technologies - 2D-electronic and 2D-infrared - two-dimensional electronic-vibrational spectroscopy (2D-EV) is the first that can be used to simultaneously monitor electronic and molecular dynamics on a femtosecond time-scale. The results show how the coupling of electronic states and nuclear vibrations affect the outcome of photochemical reactions.
