Organic solar cells with graphene

Photovoltaic devices, or solar cells, are a means of generating electricity from sunlight in an environmentally friendly manner without emissions. Among the various types of solar cells, organic photovoltaics (OPVs) are known as lightweight, transparent, thin and flexible solutions. OPVs generally consist of a charge donor layer, a charge acceptor...

Graphene-Perovskite solar cells exceed 18% efficiency

Scientists have created hybrid perovskite-graphene solar cells that show good stability upon exposure to sunlight, while still maintaining efficiency over 18% - the highest reported efficiency of graphene perovskite hybrid solar cells to date. Perovskite solar cells (PSCs) are rapidly emerging as the most promising photovoltaic technology, gaining attention on...
