Researchers at Canada’s National Institute for Nanotechnology (NINT) and the University of Alberta have developed an approach that could lead to improved performance of plastic solar cells (hybrid organic solar cells). Conventional solar cells require materials that are expensive or in short supply, such as silicon, thus there is a great interest in the development [...]

Spain has the sunshine and now appears to have the will to use its potential to generate clean energy.

Rising out of the Andalusian countryside like a gigantic obelisk, a huge concrete solar tower is surrounded by fields of more than 1,000 mirrors that are carefully positioned to reflect sunlight in order to superheat water in the tower.
