Objective
The main goal of the proposed project is to reduce the cost of photovoltaic electricity. The way to do so is based on the development of bifacial solar cells (that may receive illumination on both faces) and a static concentrator (i.e. a concentrator that does not need tracking).
The achievement of bifacial solar cells of high efficiency and low cost is a key for this project. At the laboratory level, bifacial technology has achieved efficiencies over 18% on either face, what makes promising its transference to industry. To do so, questions like the starting material and the metallization technology must be taken into account.
Static concentrators can take more advantage of bifacial cells than conventional bifacial flat modules, that need an albedo emitting surface at its rear (generally a white painted wall). Static concentrators can not only avoid the need of white painted walls but they can also concentrate the light on the cell, and so they can help cost reduction by reducing the cell area. In the present project, a static concentrator based on the multisurface synthesis methods developed at the Partner two will be developed.
Moreover, a PV module based on these concentrators may be easily integrated in a building.
Cost considerations will be almost the unique criteria to decide among the different altematives. A cost evaluation procedure for both bifacial cells and concentrators modules will be done combining the experience of the project leader (Partner One), who has already produced and commercialized bifacial solar cells and has developed several prototypes of static concentrator modules.
