A new generation liquid solar cells are being developed at SUFY Buffalo. Although the new technology is expected to have lower efficiency than conventional silicon or cadmium solar cells, the new solar cells will be much cheaper to produce and can cover much larger surfaces.
The new liquid solar cells, made of metal nanoparticles, are expected to increase the efficiency of light energy conversion. The team is aiming to achieve 10 percent conversion rate using plasmons. These are electromagnetic waves and free electrons that travel across the metal interface.
Qiaoqiang Gan, the lead researcher from the University at Buffalo claims that these plasmons are the key to developing cost effective thin-film organic solar cells.
