Abstract

Concentrated photovoltaic and liquid-flow thermocells (CPV-LITE) hybrid system is promising for full-spectrum solar utilization by effectively cooling PV and outputting more electricity. However, when using different photovoltaic materials, the performances of CPV and LITE may not be a perfect match due to its intrinsic material properties and manufacturing engineering. Herein, we demonstrated a novel hybrid system coupling LITE and CPV with optimal photovoltaic cells to promote its performance. A three-dimensional photo-thermal-electrical model of CPV-LITE was constructed considering the coupling of PV temperature and concentration ratio, wherein the multi-software collaborative computation was adopted to simplify the solution process. The CPV-LITEs with PV of distinct generation (Mono-Si, α-Si, CdTe, CIGS) were systematically investigated to obtain the optimal PV through thermodynamic and economic analyses. Results showed that among these PV, the Mono-Si presented the highest ηele of 20.0 % at 11 concentration ratios, showing a 1.0 % increase than corresponding CPV-TEG. At the electrolyte flowrate of 0.0752 m/s, the CPV-LITE can reach an optimal Pele of 1.74W for Mono-Si with a lower overall cost of 14.4 % than other PV materials. The LITE was suitable for Mono-Si, while TEG was better for the remains, which can efficiently output more electric energy by harvesting PV waste heat.
