The future of solar cells changes shape

Unique coral-shaped nanomaterials could improve the efficiency of solar cells, say Chinese scientists. 

Porous materials, such as tin oxide, have properties that make them ideal for use in solar cells, batteries, gas sensors and other devices. Changing their structure and morphology can enhance their properties, but this can be difficult to control using current preparation methods, says Jinhuai Liu at the Chinese Academy of Sciences, Hefei.  More...
