‘Self-healing’ polymer brings perovskite solar tech closer to market

June 18, 2019
With atmospheric carbon dioxide levels reaching their highest recorded levels in history, and extreme weather events continuing to rise in number, the world is moving away from legacy energy systems relying on fossil fuels towards renewables such as solar. Perovskite solar technology is promising, but one key challenge to commercialization is that it may release pollutants such as lead into the environment—especially under extreme weather conditions. According to TechXplore, a protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells (PSCs), according to scientists from the Okinawa Institute of Science and Technology Graduate University (OIST). Adding a "self-healing" polymer to the top of a PSC can radically reduce how much lead it discharges into the environment. This gives a strong boost to prospects for commercializing the technology. "While so-called 'lead-free' technology is worth exploring, it has not yet achieved efficiency and stability comparable to lead-based approaches. Finding ways of using lead in PSCs while keeping it from leaking into the environment, therefore, is a crucial step for commercialization" explains Professor Yabing Qi, head of the Energy Materials and Surface Sciences Unit and who led the study. --------------------***------------------- Source:http://ow.ly/Uk9w50uGKI5 Photo:http://ow.ly/HlsL50uGKI6 ……………………………………. ‘All rights to go to the author of the news & image as mentioned above’ -------------------------------------------
