Paper Abstract

In this paper we present the results in the development of large format (20 cm by 50 cm) cylindrical holographic mirrors (CHMs) recorded in dichromated gelatin, for use in solar chemistry applications. The realized spectral reflectivity of 400 - 440 nm is adapted to the sensitizer zinctetra-phenylporphine. Effective efficiency of the mirror (i.e. referred to the incident radiation at the desired wavelength of 420 nm) is 75% with excellent homogeneity across the aperture.
