“…8. The optical path modulation obtained, 1 n d ⋅ = 0.3912 μm for HX 104 and 1 n d ⋅ = 0.3648 μm for HX TP, is similar to that obtained by DCG investigated by the authors [7]. The thickness of the DCG emulsion in [7] was 30 µm, around the double of photopolymer thickness, and the index modulation was the half: 0.012.…”

“…In order to determine the optimal intensity for this work (with a target wavelength of 800 nm), several recording intensities were used. For each intensity several samples were recorded using different exposure energies, to obtain the index modulation 1 n for each one (as in Fig. 8).…”

“…For other photovoltaic cells with different working spectral range, the HOE would be designed in accordance to that range. If the target reconstruction wavelength is lower or equal to 800 nm the same material can be used; however, if it is higher than 800 nm another material, which could provide a higher optical path modulation 1 n d ⋅ , should be utilized.…”

Volume Holographic Optical Elements (HOEs) present interesting characteristics for photovoltaic applications as they can select spectrum for concentrating the target bandwidth and avoiding non-desired wavelengths, which can cause the decrease of the performance on the cell, for instance by overheating it. Volume HOEs have been recorded on Bayfol HX photopolymer to test the suitability of this material for solar concentrating photovoltaic systems. The HOEs were recorded at 532 nm and provided a dynamic range, reaching close to 100% efficiency at 800 nm. The diffracted spectrum had a FWHM of 230 nm when illuminating at Bragg angle. These characteristics prove HOEs recorded on Bayfol HX photopolymer are suitable for concentrating solar light onto photovoltaic cells sensitive to that wavelength range.

“…Numerous SSS designs using holographic [3][4][5][6] or dichroic [7][8][9][10] optical filters to spatially isolate solar spectral bands have been proposed. Holographic optical elements (HOE) are a versatile, inexpensive option for SSS, which can: achieve high diffraction efficiency, be used in transmission or reflection geometries, incorporate concentration, and be customized for individual designs by modifying diffracted spectral bands and dispersion characteristics [11][12][13][14] .…”

In this study the impact of outdoor temperature variations and solar illumination exposure on spectral filter material and holographic optical elements is examined. Although holographic components have been shown to be useful for solar spectrum splitting designs, relatively little quantitative data exist to demonstrate the extent to which these materials can withstand outdoor conditions. As researchers seek to investigate practical spectrum splitting designs, the environmental stability of holographic materials should be considered as an important factor. In the experiment presented, two holographic materials, Covestro Bayfol HX photopolymer and dichromated gelatin, and 3M reflective polymer filter materials are exposed to outdoor conditions for a period of several months. The environmental effect on absorption, spectral and angular bandwidth, peak efficiency, and Bragg matching conditions for the holograms are examined. Spectral bandwidth and transmittance of the 3M reflective filter material are also monitored. Holographic gratings are recorded, measured, and mounted on glass substrates and then sealed with a glass cover plate. The test samples are then mounted on a photovoltaic panel to simulate realistic temperature conditions and placed at an outdoor test facility in Tucson, Arizona. A duplicate set of holograms and 3M filter material is stored as a control group and periodically compared over the test period.
