JEONJU, Oct. 7 (Korea Bizwire) — New technology has been developed that can address the shortcomings of perovskite solar cells, including the reduction in lifespan and environmental pollution caused by lead.
A research team from Jeonbuk National University said Thursday it had developed a lead-free, eco-friendly perovskite solar cell using a tin-graphene compound material.
The research result was published in the latest online edition of the renowned journal Advanced Energy Materials.
The research team applied nitrogen-coated graphene material into two layers of tin-perovskite solar cells – the active layer and hole transport layer – in order to form a functional compound material at each layer.
With this method, the research team succeeded in greatly enhancing the light absorption rate, photovoltage and density of photoelectric current.
The efficiency of the solar cell was maintained up to more than 91 percent even after 60 days.
