Highly efficient organic solar cells with improved operation stability 2016

A new study, affiliated with Ulsan National Institute of Science and Technology (UNIST), South Korea, has presented an effective and simple strategy to simutaneously improve and stablize the performance of Organic Solar Cells.

A new type of organic solar cells (OSCs) with 11.6% efficiency has been developed by a research team, affiliated with UNIST. This solar cell maintained almost 80% of its initial efficiency after 60 days long-term test under elevated temperatures up to 120℃.

In the study, the research team, led by Prof. HyeSung Park and Prof. Chang Duck Yang of Energy and Chemical Engineering has developed an effective and simple strategy to simutaneously improve and stablize the performance of OSCs by applying small amounts of the macromolecular additive to the photoactive layer in OSCs. This is a unique and unprecedented method, which applies the macromolecular additive to control the molecular weight.
