Gwangju Institute of Science and Technology Researchers Demonstrate Improved Performance of Transition Metal Oxide Based Organic Photovoltaics
GWANGJU, South Korea, Oct. 18, 2022 /PRNewswire/ -- Harnessing the power of the sun and converting it into electricity using photovoltaic solar cells is one of the top contenders for combating the current energy crisis. To this end, researchers have developed organic photovoltaics (OPVs) with transition metal oxide (TMO) thin-film interfacial layers as a cost-effective alternative to commercial silicon solar cells. OPVs are known for their excellent photochemical properties and low-cost mass producibility. However, the TMO layer often suffers from a degraded electrical conductivity owing to the presence of lingering organic metal-binding ligands generated during their synthesis. This greatly limits the OPVs from reaching their full potential.

- However, the TMO layer often suffers from a degraded electrical conductivity owing to the presence of lingering organic metal-binding ligands generated during their synthesis.
- A team of researchers led by Prof.Kwanghee Lee from Gwangju Institute of Science and Technology, Korea found a way to overcome this challenge.
- Further, the inverted OPV configuration showed 17.6% improved efficiency, with over 70% retention of the initial efficiency for up to 100 hours.
