Perovskite solar cells discharge large volume of lead into the environment. And, lead is highly toxic and the impact of this is usually catastrophic. Researchers propose adding a layer of epoxy resin in the solar cells to prevent this. Further, the researchers are from Okinawa Institute of Science and Technology Graduate University.
Adding a layer of self-healing polymer reduces the discharge radically. Therefore, it boosts the prospects of commercializing this technology. In the current environmental conditions, when the atmospheric CO2 level is skyrocketing, the world is turning to renewable energy.
Perovskite Solar Technology Faces Challenge from Lead Leakage
An otherwise promising technology, some critical challenges prevent commercialization of perovskite technology. Perovskite cells release large volumes of lead under extreme weather conditions. And, bothers the potential of scaling the application of these solar cells.
Professor Yabing Qi is the unit head at the Energy Materials and Surface Sciences unit, Okinawa Institute of Science and Technology Graduate University He explains that although perovskite solar cells effectively transform sunlight into electricity, the fact that they carry lead increases concerns regarding the environment. Professor Qi led a study on perovskite solar cells, which was published in Nature Energy.
“This alleged 'lead-free' technology, although is yet to achieve stability and efficacy that can be compared to lead-based approaches, it is worth exploring. Therefore, looking for ways to use lead in perovskite solar cells without any leakage into the environment is very important for its commercialization,” he added.
