| description | Holographic optical elements (HOEs) are promising for solar energy collection due to their advantages of lightweight and high efficiency, but the narrow reconstruction of their angular and spectral widths limits their application. This paper proposes a novel holographic lens array solar collector (HLASC), which can collect light from a large angle range with an expanded spectrum. The large acceptance angle is achieved by a holographic lens array with a large relative aperture. To expand the collection spectral width within a large incident angle, the collection spectrum is spatially allocated within a single lens range. The methods of single-wavelength recording and multi-wavelength reconstruction contribute to the flexible design and simple fabrication of the HLASC. The optical experiment demonstrates that the HLASC can collect the entire visible spectrum in a range greater than 54°. We believe that an expanded reconstruction angle and wavelength will promote the widespread application of HOEs in solar energy collection. |
