Compact PV-CSP: Extending solar power production beyond daylight

Integrated Concentrating Solar/Photovoltaic Hybrid Concepts—Technological Discussion, Energy Yield, and Cost Considerations

“…Yu et al discussed a further implementation: PV cells with good transmittance of sub‐bandgap photons in combination with a back reflector. [ 6 ] This option is also studied by Ziyati et al [ 10,11 ] Here the reflection is angle independent. In this work, still the first approach is followed, since it allows the use of all commercially available PV cells.…”

“…The CRS simulated by Ziyati et al [ 10 ] was located at Targassonne, France, a mediocre CSP location in terms of annual DNI, where the diffuse fraction of the incident radiation is higher than on more suitable CSP locations. [ 11 ] For that reason, it is assumed that the PV‐Mirror can achieve better results there than at the more suitable locations as it is able to convert a fraction of the diffuse irradiation.…”

“…Ziyati et al developed a model for using the PV-Mirror in CRSs. [10,11] Liew et al modeled the use of the PV-Mirror in a collector for supplying heat for domestic requirements. [30] 2.3.3.…”

“…Increased amount of installations will lead to LCOE decrease also for CSP.One path to systematically increase the cost-competitiveness of CST technology is the exploitation of unused potentials by combining it with PV. In this work, four combined CST/PV concepts are compared: concept #1, the Rear-PV, [3][4][5] concept #2, the PV-Mirror, [6][7][8][9][10][11] concept #3, the bifacial PV-Mirror, [9] and concept #4, the Spillage-concentrating PV (CPV). [12,13] The goal of this work is to derive parameters for these four concepts for their quantitative comparison in terms of energy production and investment costs.…”
