Researchers Demonstrate Improved Performance of Organic Photovoltaics
GWANGJU,South Korea—Organic photovoltaics with a transition metal oxide (TMOs) interface layer are emerging as a promising alternative to conventional silicon-based photovoltaics. However, unwanted organic metal-binding ligands left behind in the TMO synthesis process often affect their electrical properties. Now, Gwangju Institute of Science and Technology researchers have addressed this issue using a technique called anion-induced catalytic reaction, which removes the residual ligands, resulting in a 20-fold enhancement in electrical conductivity.
