Scientists Develop a More Efficient and Economical Solar Cell Based On Graphene and Perovskite
The Group of Photovoltaic and Optoelectronic Devices (DFO) at the Universitat Jaume I in Castelló, led by the professor of Applied Physics Juan Bisquert, together with researchers from the University of Oxford, have created and characterized a photovoltaic device based on a combination of titanium oxide and graphene as charge collector and perovskite as sunlight absorber. The device is manufactured at low temperatures and has a high efficiency.
The results of this study were recently published in Nano Letters. The article is the result of the research work carried out the last year by the Group of Photovoltaic and Optoelectronic Devices on the topic of photovoltaic solar cells based on solid pigments with perovskite structure.
This scientific work has combined new and promising materials based on perovskite structure, which absorb sunlight very effectively, with graphene, a material of great interest today for its properties, versatility and low cost. Graphene is a material consisting of carbon monolayers. Its use has generated high expectations in new advanced technologies, such as high-performance lithium batteries, electronics, video screens and technological applications.
