The April edition of the monthly seminar series of the Distance Learning Institute (DLI), University of Lagos, spotlighted a revolutionary technology called “perovskite solar cells” and its ability to miniaturize energy solutions, thus creating powerful systems in smaller, more accessible formats.
Titled “Optimization of Lead-Free Perovskite Solar Cell Using Numerical Modelling and Simulation,” the engaging session was held on Wednesday, April 30, 2025, at the Red Block Conference Building, DLI Complex, UNILAG, Akoka. The session featured a member of faculty, Dr. Adeyinka David Adewoyin, unveiling Perovskite Solar Cell as a breakthrough that could transform Nigeria’s energy future.
In his presentation, the Physics Lecturer traced the origins of perovskite, and its discovery by Gustav Rose in 1839 before it was named after Russian mineralogist, Lev Perovski. He disclosed that “initially overlooked, its potential as an affordable, efficient energy solution has now been unlocked in recent decades.”
Dr. Adewoyin explained that perovskite’s unique ability to adjust its properties makes it an ideal material for creating compact, efficient energy solutions in Nigeria.
While addressing environmental concerns, he emphasized the eco-friendly nature of lead-free perovskite solar cells, which he posited decompose harmlessly after their lifespan, unlike some toxic technologies.
Dr. Adewoyin’s presentation painted a future where Nigeria could harness affordable and clean energy to power homes, businesses, and innovations. His passion for sustainable technology inspired attendees, sparking discussions on how such advancements could transform the nation’s energy landscape.
Earlier, the DLI Director, Prof. Risikat Oladoyin Dauda opened the seminar by warmly welcoming attendees and expressing appreciation to the institute’s academic and non-academic staff for their dedication in ensuring the event’s success. She emphasized DLI’s tradition of engaging with distinguished scholars to foster knowledge exchange within the academic community.
Prof. Dauda underscored the role of science in uncovering transformative discoveries, and addressing global challenges, expressing her anticipation for an insightful and impactful seminar that would inspire and benefit all participants.
