Researchers double efficiency of see-through solar cell

Researchers double efficiency of see-through solar cell

Researchers at UCLA have developed a new kind of see-through solar cell that could be used on windows, car sunroofs, smartphone displays and other transparent surfaces to harvest energy from the sun. First developed in 2012, the researchers have now almost doubled the efficiency of this technology getting it even closer to commercial viability. The solar device is comprised of two thin polymer solar cells that can be made in shades from light green and gray to brown, which allows them to blend in with the surface of buildings or other structures. The solar cells absorb more light than single-layer solar devices, use light from a wider portion of the solar spectrum, and incorporate a layer of novel materials between the two cells to reduce energy loss. Called a tandem-structure transparent organic photovoltaic (TOPV) device, the technology originally had an efficiency of on...
