Utilizing the light reflected by simple means onto the rear surface of solar cells is an effective way of lowering the cost of solar electricity, since more power is generated per cell. Innovative bifacial photovoltaic modules have been introduced, such as a multifunctional bifacial PV sun-shading element which is based on bifacially sensitive solar cells in combination with a white semitransparent reflector back sheet. Not only is sunlight collected by its front and rear surface efficiently converted into electricity, but also diffuse glare-free daylight is provided. Other applications include relatively narrow bifacial modules installed at a certain distance in front of a reflecting background. In all cases power gains of more than 50% can be achieved with little extra cost compared with monofacial modules. Copyright (C) 2003 John Wiley Sons, Ltd.
