Solar Cells Consisting of Nanocrystals

Still working on improving solar technology, a group of scientists from the University of Southern California, created a new solar cells built by Nanocrystals looking liquid and could be used to print or paint any plastic surface or color.

The design of new cells is small enough to fit 250 million head of a pin. The manufacturing process is much cheaper than the current silicon solar cells, but the efficiency is much poorer, so we can see this technology in the market will be much improved.

That is why the technology will take many years to reach the market. Scientists are still working to the next step which is to replace this with another harmless compound.
