Description
Summary:In present work, different possible aspects of holographic PV concentrators like wide acceptance angle, wavelength selectivity and maximum efficiency operation have been investigated by controlling different processing parameters like depth of refractive index modulation, film thickness and fringe spacing. We have discussed and analyzed individual as well as cumulative effect of processing parameters on angular selectivity, wavelength selectivity and efficiency. In addition, we are also reporting optimized value of the processing parameters for designing high efficiency holographic concentrator.
