Every component of present era solar cells is superbly optimized leaving only one major loss mechanism, the poor utilization of solar spectrum. Nonetheless, solar electric power generation represents less than 1% of the electric power consumed globally. Photovoltaic solar cells must increase the power produced per unit cost. Spectral management that broaden the response without consuming useful light will lead to improved efficiency without increased production cost. Applying amplified Raman scattering to commercial solar cells was investigated in this dissertation. The portion of the solar spectrum with energy less than the photovoltaic band gap cannot be converted into electrical energy. By Raman scattering a portion of those un-used photons can be up-converted in energy and used by the photovoltaic devices. Small particle systems has been used to amplify the Raman scattering due to the extremely long optical path length (> km) are generated by the multiple scattering by the particulate systems. The understanding of excitonic-based energy conversion used by plants could also lead to improved photovoltaic devices. Exciton transfer mechanism was investigated for the improved next generation solar cells. The absorption of chlorophyllin, derivative of chlorophyll, in different environments was discussed. A better understanding of the absorption behavior of chlorophyllin provides new insights into photosynthesis and solar cell device.
