Glass in Photovoltaics

Solar power technology uses arrays of photovoltaic cells to convert light from the sun into electricity. The solar cells are embedded between two glass panes and a special resin is filled between the panes, securely wrapping the solar cells on all sides. Each individual cell has two electrical connections, which are linked to other cells in the photovoltaic module, to form a system which generates a direct electrical current when light shines on the cell.

Photovoltaic glass is a special glass with integrated solar cells. Photovoltaic glass provides the potential for the electrical power for an entire building to be produced within the roof and façade areas. This "building-integrated photovoltaics" technology is used increasingly in new buildings, both residential and commercial, either to provide a principal or secondary source of electricity. It is also possible to retrofit photovoltaic arrays into existing buildings. The modules can be connected either in parallel or series depending on the desired design. Photovoltaic arrays also come in various shapes and colours, so that they can be used on, for example, conservatories to provide shading as well as producing electricity.
