Solar Energy In 3D: Copying Nature To Get The Best Results

China develops 3D conic device to increase solar-thermal conversion. The device, named 'Artificial Transpiration' is inspired by the transpiration process of trees, an article published online by the National Science Review, an English language journal affiliated to the Chinese Academy of Sciences, said.PTI

What is tree transpiration?
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.

Solar Energy In 3D: Hollow-Cone Structure Increases Solar-Thermal Conversion Efficiency 

The device, named 'Artificial Transpiration' by Zhu Jia and his team from the Nanjing University, is inspired by the transpiration process of trees, an article recently published online by the National Science Review, an English language journal affiliated to the Chinese Academy of Sciences, said. It has a special 1D water path within it, which can reduce the energy loss in conduction, China's state-run Xinhua news agency quoted the article as saying.

The cone structure, based on a graphene film, can collect more sunlight throughout the day when compared with a flat device, as about 10 per cent to 50 per cent of sunlight is diffusive. Thus it performs even better in the real world than in the laboratory, it said. As a result, the device can enhance the solar-thermal conversion rate to 85 per cent, which is much higher than the 40 per cent rate of common devices, it said.

How does a tree get water to the top?
Water mostly enters a tree through the roots by osmosis and any dissolved mineral nutrients will travel with it upward through the inner bark's xylem (using capillary action) and into the leaves

Many sectors have refrained from using solar power because of its low conversion rate caused by losses in radiation, convection and conduction. The device will open new possibilities in utilisation of solar energy. 
Zhu's team first applied this structure to solar waste-water treatment, and the test showed that it could not only retrieve clean water but also recycle heavy metals such as copper and cadmium. In the future, the structure can be further optimised to have a longer life and recycle more heavy metals.
