‘Active buildings’ clean energy project aims to revolutionise construction

Making construction greener is the goal for a new clean energy innovation scheme that generates electricity from “active buildings”. The  project, which has been launched led by a consortium led by Swansea University in Wales, sets out to develop new building materials that create renewable energy from heat and light. Conventional walls, roofs and windows can be replaced […]

Organic solar cells achieve commercial output

Chinese researchers have taken what they say is a major step forward for the development of a new generation of solar cells. Manufacturers have long used silicon to make solar panels because the material was the most efficient at converting sunlight into electricity. But organic photovoltaics, made from carbon and plastic, promise a cheaper way […]
