Exploring Bandgap Engineering on Photovoltaics and their Possible Economic implications

Bandgap an intrinsic property of molecules on nanoscale, has capability of making alterations in the characteristics of the material through cataclysmic changes from interaction with light. Ultraviolet spectrographs of three organic extracts were explored for their optical frequency and possible use as communication organic optical fiber. The bandgaps of these dye extracts were determined and tailored by varying their absorptivity of ions in electrolytic solvents. A distinctive absorption power, transmittance and amplitude promoted vital regional shifts in wavelength. Interaction with radiation absorbed, influenced a Fermi energy change within a large band gap ≈ 4eV, which is a hypothetical line of symmetry. Results revealed that all the bands below that energy level were entirely filled, whereas all higher-lying bands were completely or nearly empty, with the exception of minimal thermal excitation which is induced at high temperatures.
