| Abstract: | A photovoltaic/thermochemical hybrid solar system based on spectral splitting is studied in this paper.In this solar system,the full spectrum of solar energy is split into several part to be used according to wavelengths of sun lights.Solar radiation in the spectrum suitable for photovoltaic conversion is converted directly to electricity using a photovoltaic cell.The solar energy in rest of the spectrum is converted thermal energy to drive a methanol vapor decomposition reaction for syngas production.The experimental results show that when the direct solar radiation is 712.8 W·m-2 and methanol flow rate is 2.7 kg·h-1,the system efficiency reaches to 31.18%.The system realizes the conversion of low-grade solar energy to high-grade electrical energy and chemical energy and provides a new idea for the efficient utilization of the full spectral solar energy. |
