Solar cells are getting more viable sources of energy -- and as they become more efficient, they're only getting smaller and less expensive to provide. Liquid nanocrystal cells are traditionally inefficient at converting sunlight into electricity, but by adding an artificial ligand to aid transmit currents, researchers at USC have improved their effectiveness. The benefit of these liquid solar cells? They're cheaper than single-crystal silicon wafer solutions, and they are also an incredibly minuscule four nanometers in size, meaning greater than 250 billion could fit at the head of a pin. Moreover, they are often printed onto surfaces -- even plastic -- without melting. Ultimately, the goal of this research is to pave the style for ultra-flexible solar panels. However, the scientists are still experimenting with materials for constructing the nanocrystals, because the semiconductor cadmium selenide they've used to date is simply too toxic for commercial use.
