Definitions
- the present invention relates to a new module for photovoltaic power generation and radiation detection.
- Concentrator photovoltaics CPV technology
- Concentrator photovoltaics is a technology that, in principle, makes it possible to save high-quality solar cells through light concentration and thus lower the costs of solar power generation.
- the optical systems for light bundling cost less than efficient solar cells (http://www.solarserver.de/news/news-10404.html, 23.03.2009).
- To concentrate the solar radiation use is made of either mirrors (DE 11 2006 001229 T5) or lenses (DE 20 2007 000529 U1, DE 10 2005 047132 A1, DE 10 2004 001248 B3, DE 20302944 U1, DE 19937448 A1).
- microconcentrators for efficiency enhancement in concentrator solar cells
- the production of microconcentrators requires elaborate microstructure techniques and their use is only suitable for special applications
- Fluorescence collector plates based on acrylic glass and doped with organic fluorescent dyes are also used for the radiation collection The radiation is collected over a large area and reaches the narrow edges of the fluorescence collector where the solar cells are applied (PD Swift, GB Smith, "Color considerations in fluorescent solar concentrator stacks", Applied Optics, Vol.42 (2003), no. 25, p.5112-5117). Fluorescence collectors hardly came into practical use, since their efficiency was not sufficient by optical losses in the collector.
- thin-film solar cells or solar cells made of silicon wafers are applied to a highly transparent solar glass substrate, which directs the solar radiation to the solar cells and protects them from external influences.
- the present invention provides a photovoltaic module in which thin film solar cells based on silicon, cadmium telluride, cadmium sulfide, copper indium gallium diselenide (CIGS), copper indium sulfide (CIS), copper Indium gallium sulfur selenium and other mixed compounds of these elements and / or solar cells and semiconductor detectors of silicon wafers, gallium arsenide and indium phosphide compounds, germanium, selenium, gallium indium phosphide, gallium indium arsenide and other mixed compounds from these elements or organic solar cells and light-transporting optical layers are applied on a solar glass or other suitable optical substrate in a checkerboard and / or other solar cells and light-transporting layers alternating arrangement, wherein the light-transporting layers used with respect to the solar cells or detectors are much cheaper.
- solar cells instead of solar cells, other optoelectronic detectors in thin-film form or as classic semiconductor detectors can be used.
