Photovoltaic (PV) conversion is highly wavelength-dependent. The efficiency of a PV system is maximum when converting photons of energy close to the bandgap energy of solar cells. In a spectral-splitting solar cell system, an appropriately designed holographic lens provides wavelength-selective performance to disperse and concentrate a specific spectral region of solar radiation with appreciable diffraction efficiency. However, for holographic lenses, the angular range over that diffraction efficiency remains appreciable is limited. To overcome the difficulties associated with the limited acceptance angle (angular selectivity) of a single holographic lens, an investigation on the design aspect of a multiplexed off-axis holographic lens has been made for the collection and concentration of sunlight effectively over a wide angular range with appreciable diffraction efficiency. Processing parameters for a typical thick-phase holographic lens have been optimized to get the maximum value of the acceptance angle. Based on the theoretical design, a multiplexed hologram consisting of four angularly multiplexed holographic lenses of equal fringe spacing has been recorded. Experimental curves for the variation of diffraction efficiency with the angle of reconstruction have been presented to show the effectiveness of such multiplexed lens for solar tracking. Simulation results for the multiplexed holographic lens are also presented, which shows a good agreement with the experimental results. Results show that such off-axis multiplexed holographic lenses can advantageously be used for wavelength-selective performance with appreciable diffraction efficiency over a wide angular range.

“…One reason for this is that most of the solar concentrators were developed for photovoltaic power generation and thermal applications [7,8]. While numerous daylighting systems have been demonstrated with light pipes [9][10][11] and optical fibers [12][13][14][15][16][17][18][19][20][21], most of the designs have a large number of tracking reflectors and lenses and, thus, require an adequate area to be installed.…”

Daylighting has a very effective role in reducing power consumption and improving indoor environments in office buildings. Previously, it was not under consideration as a major source of renewable energy due to poor reliability in the design. Optical fiber as a transmission medium in the daylighting system demands uniform distribution of light to solve cost, heat, and efficiency issues. Therefore, this study focuses on the uniform distribution of sunlight through the fiber bundle and to the interior of the building. To this end, two efficient approaches for the fiber-based daylighting system are presented. The first approach consists of a parabolic mirror, and the second approach contains a Fresnel lens. Sunlight is captured, guided, and distributed through the concentrator, optical fibers, and lenses, respectively. At the capturing stage, uniform illumination solves the heat problem, which has critical importance in making the system cost-effective by introducing plastic optical fibers. The efficiency of the system is increased by collimated light, which helps to insert maximum light into the optical fibers. Furthermore, we find that the hybrid system of combining sunlight and light emitting diode light gives better illumination levels than that of traditional lighting systems. Simulation and experimental results have shown that the efficiency of the system is better than previous fiber-based daylighting systems.
