The SOLFIN (SOLar synthesis of FINe chemicals) facility hosts two compound parabolic concentrators (CPC) reactors built between 1996 and 1997 at the Plataforma Solar De Almería, in Spain . The first reactor is constituted by an array of eight 48-mm tubes placed in the focus of a 152 mm wide and 1-m long CPC. . A convincing example of how solar light can be exploited for the photochemical synthesis of fine chemicals on a large scale is constituted by the SOLARIS (solar photochemical synthesis of fine chemicals) reactor and its successor. . A so-called “line focusing solar reactor” was employed between 1992 and 1997 at the Max Planck Institute (MPI) of Mülheim (Germany) for some di-π. . Compound parabolic concentrators (CPC) are essentially “round W” shaped reflectors generally used to focus solar light on a receiver tube. Since the diameter of the tube is. .

Finally, an outlook on the future of solar photochemistry in flow is included. The sun constitutes the most sustainable light source available for photochemistry. However, the use of solar light in photochemistry comes with significant hurdles associated with its polychromatic nature and fluctuating ground intensity.
It is a natural consequence that the majority of photoreactors specifically designed for solar application are continuous-flow reactors. In this chapter, the applications of continuous-flow chemistry to organic solar photochemistry will be described.
The wide application of flow in solar photochemistry is not fortuitous but constitutes the deliberate choice of maximizing the photon flux received by the reaction mixture. In fact, given the relatively low intensity of the solar irradiance, the efficient use of solar photons is of paramount importance.
Solar photochemistry as a key component in a solar polygeneration scheme can lead to very high electricity-equivalent system efficiency, as shown for the PNC and POC reactions. Each photochemistry application should be investigated individually to avoid low-performance cases such as wastewater photocatalytic disinfection.
The efficiency of a Z-scheme photocatalyst for solar energy conversion was determined to be 0.1%. Apparent quantum yields of the Z-scheme systems were improved from 0.4% to 3.9-4.2% at 420 nm when SrTiO3:Rh, prepared by HT and PC methods, was used as a H2-evolving photocatalyst instead of that prepared by a solid state reaction.
Solar spectral splitting and cascade utilization is an efficient way to improve solar energy conversion efficiency. This study analyzes the photovoltaic-photo/thermochemistry synergistic conversion system from a thermodynamic perspective.
Since efficient solar photochemistry is inextricably linked with a flow operation mode, the barrier for adoption is currently significant as both a batch-to-flow and a lamp-to-solar conversion are needed. ...
