Summary:The present invention relates to improvements in solar cell and solar panel photovoltaic materials which cause the solar cells/panels to operate more efficiently. In particular, the present invention focuses primarily on matching or modifying particular incident light energies (e.g.,from the sun) to predetermined energy levels in a solar cell photovoltaic substrate materi al required to excite, for example, electrons in at least a portion of the substrate material in a desirable manner. In this regard, for example, energ y levels of incident light, and thus, corresponding particular wavelengths, su ch as desirable wavelength (.gamma.1), or frequenices of incidient light, can b e at least partially matched with various desirable energy levels in a substra te material by filtering out at least a portion of certain undesirable incident light, such as that of wavelength (.gamma.2), that comes into contact with a t least a portion of a surface of a solar cell photovlataic substrate.
