Due to the inherent broadband nature of the solar radiation, combined with the narrow spectral sensitivity range of direct solar to electricity devices, there is a massive opportunity to manipulate the solar spectrum to increase the functionality and efficiency of solar energy conversion devices. Spectral splitting or manipulation facilitates the efficient combination of both high-temperature solar thermal systems, which can absorb over the entire solar spectrum to create heat, and photovoltaic cells, which only convert a range of wavelengths to electricity. It has only recently been possible, with the development of nanofabrication techniques, to integrate micro-and nano-photonic structures as spectrum splitters/manipulators into solar energy conversion devices. In this paper, we summarize the recent developments in beam splitting techniques, and highlight some relevant applications including combined PV-thermal collectors and efficient algae production, and suggest paths for future development in this field.

“…In the thermally de-coupled case some sort of filter or spectral splitter is necessary and could be based on thin film reflector/absorber [37][38][39][40] or fluid filter [20,21,23,41]. For the thin film reflector/ absorber arrangement typically stacks of varied refractive index materials are constructed to create the necessary spectral reflection [12,16,17,19,37,38,40]. In the direct absorption approach the working fluid in the thermal portion of the collector acts as the spectral splitter; spectrally selective is achieved either through the fluid itself [18,23] or through the suspension of small particles [20,21].…”

“…Thomas and Guven [7] considered the effects of optical errors and the geometry on the circumferential flux distribution around the absorber tube. Jiang et al [8] used the spectral beam splitting method to develop optical model for two-stage PTCs, which considered the optics cone and the absorber tube diameter for an incident angle of 0 . He et al [9] calculated the flux distribution using the MCRT method with consideration of the optics cone, collector reflectivity and glass transmissivity to analyze the effects of the GC and rim angle.…”

a b s t r a c tThe parabolic trough collector is an important component of parabolic trough solar thermal power generation systems. Coordinate transformations and the Monte Carlo Ray Trace (MCRT) method were combined to simulate the circumferential flux distribution on absorber tubes. The simulation model includes the optics cone with non-parallel rays, geometric concentration ratios (GCs), the glass tube transmissivity, the absorber tube absorptance and the collector surface reflectivity. The mode is used to analyze the effects of absorber tube installation errors and reflector tracking errors. The results are compared with reference data to verify the model accuracy. Influences of installation and tracking errors on the flux distribution are analyzed for different errors, incident angles and GCs. For a GC of 20 and 90 rim angle, X direction installation errors are À0.2%~0.2%, Y direction installation errors are À1.0%e0.5%, and the tracking error should be less than 4 mrad. As the incident angle increases, the errors become larger, but the errors become smaller as concentration ratios are increased. The results provide foundations for heat transfer analysis of the absorber tube, for parabolic trough plant to ensure the safe intensity, and for economic analysis of the installation process and control system.
