Definitions
- the present invention relates to the field of photovoltaic conversion.
- Electric generators comprising photovoltaic cells are known in the prior art. These cells are formed by semiconductor barriers delivering an electrical signal depending on the light intensity illuminating their surface. Various works have been carried out to improve the yield of such cells.
- a first series of works concerns the improvement of the cells themselves, by the production of monocrystalline cells for example. These improvements result in cells whose manufacturing cost is extremely high.
- US patent US5813238 also describes a solar collector having long-lasting fluorescent properties comprising a polymer matrix, a dye, and a stabilizer.
- the polymer matrix is composed of polycarbonate and the dye is chosen from the group consisting essentially of thioxanthone, perylene imide and / or thioindigoide compounds.
- This patent proposes also to position reflective elements so that the collected sunlight can be directed to a solar cell.
- US Patent US4367367 describes a collector adapted to concentrate solar energy on a photoelectric cell comprising at least one fluorescent dopant. The cell is fixed to an edge of the collector, which is coated with a reflective coating.
- the US patent US4395582 also describes a solar converter comprising a substrate doped with photoactive combinations called “light cascades”, to improve the quality of the light spectrum illuminating the photoelectric cells.
- the object of the invention is to provide an improved photovoltaic generator, having a high efficiency for a small footprint.
- the invention relates, in its most general sense, to a photovoltaic generator comprising at least one photovoltaic cell and a transparent matrix deposited with at least one optically active material having an absorption wavelength ⁇ a and a length d re-emission wave ⁇ r , the optically active material being chosen so that ⁇ a corresponds to a range of lower sensitivity of the photovoltaic cell than ⁇ r , the matrix comprising a reflective coating, characterized in that the matrix present on the surface input a dichroic filter substantially reflecting wavelengths greater than about 950 nm, and substantially transparent for wavelengths less than 950 nm, and on the surface opposite to the input surface a reflective coating for the lengths wave greater than 400 nm, the photovoltaic cell being included in the transparent matrix.
- the matrix is formed by a strip of polymethyl methacrylate doped with light cascades.
- the entry surface of the matrix is coated with an interference layer having a maximum transmission rate for wavelengths between 330 and 900 nm and a maximum reflection rate for wavelengths greater than 950 nm.
- the surface opposite to the entry surface of the matrix is coated with a diffusing reflecting layer having a maximum reflection rate for wavelengths between 300 and 600 nm, a rate of significant absorption for wavelengths of the order of 600 nm and a significant diffusion rate for wavelengths of approximately 950 nm.
- the lateral zones of the matrix are coated with a reflecting layer.
- the generator according to the invention comprises a plurality of photovoltaic cells arranged in planes substantially perpendicular to the input surface.
- the invention will be better understood on reading the description which follows, referring to the appended drawings where: the single figure represents a perspective view of a second embodiment.
- the single figure shows a sectional view of a generator according to the invention. It consists of a rectangular block (1) forming a transparent polymethyl methacrylate (PMMA) matrix.
- PMMA polymethyl methacrylate
- These light cascades have the effect of mainly absorbing the wavelengths corresponding to the ranges of low sensitivity of the photovoltaic cells, and of high energy of the solar spectrum, and of shifting the energy towards wavelengths corresponding to ranges of high sensitivity of photovoltaic cells.
- absorption takes place between 360 and 600 nm
- re-emission takes place around 600 nm.
- the input surface (2) of the matrix is coated with a dichroic interference filter reflecting radiation of wavelength greater than 950 nm, and transparent for wavelengths between 330 nm and 900 nm.
- the opposite surface (3) as well as the lateral faces (4, 5, 6) are coated with a white reflector having an absorption peak around 600 nm and a reemission peak around 950 nm.
- the matrix (1) also comprises a plurality of photovoltaic cells (7) arranged in planes (8 to 10) perpendicular to the entry surface (2).
- the cells are encapsulated in the matrix at the time of manufacture.
- Such a configuration makes it possible to increase the efficiency of the generator by a factor of 11 compared to a generator according to the state of the art, having an identical input surface.
- the ratio between the input surface SI and the cumulative surface S2 of the photovoltaic cells is of the order of 100.
- the cells are glued to certain lateral faces of the parallelepiped block.
- This dopant may be, for example, a rare earth, in particular a rare earth oxysulfide, and more particularly the product sold under the trade name of "LUMILUX Green UCZ" or the product "LUMILUX IR CD 142" from the company RIEDEL from HA ⁇ N.
