Recording of Holographic Solar Concentrator in Ultra Fine Grain Visible Wavelength Sensitive Silver Halide Emulsion

Holography is an optical technique which is involved in the solar applications specifically solar concentration. Visible spectrum of solar light concentration on wavelength depended solar cells is effective way to enhance the diffraction efficiency of the solar cells, this is prime aim of this work. Initial step of successful recording of high diffraction efficiency phase holographic optical element were recorded. For this, we used ultra fine grain visible wavelength spectral sensitive silver halide holographic emulsion from Ultimate holography. The novelty of this work is three different laser sources of 442nm, 532nm and 633nm were used for multiplex holographic transmission lens in a same emulsion and applied for solar concentration. We optimize exposure sensitivity for each laser wavelengths and combined wavelengths in order to obtain the multiple band response of the material. The detail study of holographic optical elements recording is explained.
