| 摘要 |
<p>The invention concerns a photovoltaic generator comprising at least a photovoltaic cell and a transparent matrix deposited with at least an optically active material having an absorption wavelength μa and a re-emission wavelength μr, the optically active material being selected such that μa corresponds to a range with least sensitivity of the photovoltaic cell than μr, the matrix comprising a reflecting coating. The matrix has on its input surface a dichroic filter substantially reflecting the wavelengths longer than about 900 nm, and substantially transparent for wavelengths shorter than 950 nm, and on the surface opposite to the input surface a reflecting coating for wavelengths longer than 400 nm, the photovoltaic cell being contained in the transparent matrix.</p> |
