“…[248] Some recent publications have reported the use of the light emitted by LSCs to produce photochemical reactions. [249][250][251][252][253][254] Debije, Noël and co-workers have developed PDMS LCSs doped with fluorescent dyes to convert sunlight into a narrow spectral band and transport that energy to embedded microchannels to produce photochemical reactions ( Figure 16).…”

Luminescent solar concentrators (LSCs) are optical systems that absorb, convert, and concentrate solar light by means of photoluminescence of an emitting material embedded in a transparent waveguide. LSCs combine large possibilities of variation of shape, flexibility, color, and transparency and can operate under direct or diffuse light. LSCs were actively investigated in the period 1975–1985 in view of photovoltaic (PV) conversion. After 20 years of sleep, research on LSCs has reemerged in the first years of the millennium driven by their potential application for PV conversion in built environment. Research on LSCs aims at the development of new active and passive components, namely emitting and light‐guiding materials, and at the reduction of the loss factors associated with the elemental processed involved in the operation in order to improve power conversion efficiency. After a brief historical account, the operating principles, characterization, components, technology, and applications are reviewed. Finally, the performance of LSCs are critically discussed in a global perspective with particular emphasis on the basic contradiction between light concentration and conversion efficiency leading to some suggestions for future development of the topic.

“…[251][252][253] Liu et al have used a LCS doped with giant QDs to irradiate a photoelectrochemical cell for hydrogen production. [254] Although a significant improvement of stability was reported, the photo-current drops by one order of magnitude with a LSC as irradiation source.…”

“…In the case of a well‐known photocathodes like Cu 2 O, this reaction leads to the formation of metallic Cu. No evidences of Cu 2 O oxidation were achieved with the use of XAS, meaning that there is no self‐oxidation of the material induced by free holes generated in the material, but this process can still occur on other photoactive materials …”

Photoelectrochemical water splitting (PEC‐WS) is a promising route to obtain hydrogen (and oxygen) from sunlight and water. However, too many semiconductors show poor stability, due to photodegradation phenomena in aqueous solutions, thus loosing efficiency under operative conditions. Aim of this paper is to introduce a simple and fast method for screening different semiconductor materials and identify their efficiency in H2 (or O2) production with respect to photocorrosion. This method could be used with any finely dispersed semiconductor (powder) for a fast, preliminary evaluation of the material's behaviour without interferences from the supporting material (i. e. FTO) or any binder. The method is based on the combination of scanning electrochemical microscopy (SECM) in the tip generation/substrate collection (TG/SC) mode and of cavity microelectrodes as SECM tips. Here, we show results obtained on three powder materials, namely core‐shell CuI/CuO, CuI and TiO2.
