  • optical modeling for a two stage parabolic trough concentrating photovoltaic thermal system using spectral Beam Splitting technology
    Solar Energy Materials and Solar Cells, 2010
    Co-Authors: Shouli Jiang, Peng Hu, Songping Mo, Zeshao Chen
    Abstract:

    Abstract A two-stage parabolic trough concentrating photovoltaic/thermal (PV/T) system is described, which contains a concentrator, a spectral Beam Splitting filter, an evacuated collector tube and the solar cell components. The nondimensional optical model with the focal length of the concentrator as the characteristic length has been developed to analyze the properties of the concentrating system using the Beam Splitting filter. The geometry concentration ratio and the size of solar image at different structure parameters have been obtained. Based on the ray tracing algorithms, a detailed three-dimensional model is set up to evaluate the local radiation flux density distribution on the elements’ surfaces. And the effects of the solar brightness distribution and optical errors (e.g., alignment error and tracking error) are also involved. Furthermore, the spectral distribution of the solar radiation is illustrated with the Beam Splitting filter, which has been specially designed using the needle optimization method. It is shown that using the filter the heat load of the cell can be reduced by 20.7%, up to 10.5% of the total incident solar energy can be recovery by the receiver, and the overall optical efficiency in theory is about 0.764.

  • Modeling for Two-Stage Dish Concentrating Spectral Beam Splitting Photovoltaic/Thermal System
    2009 Asia-Pacific Power and Energy Engineering Conference, 2009
    Co-Authors: Shouli Jiang, Zeshao Chen
    Abstract:

    Detailed optical and electric models are presented to evaluate the performance of the two-stage dish concentrating spectral Beam Splitting photovoltaic/thermal (TDCS) system. It mainly consists of parabolic concentrator, spectral Beam filter, heat receiver and the cell component. The Beam filter coated with 38 layers is designed and manufactured. Three-dimensional optical model, considering the effect of solar intercept angle and tracking error, is developed using ray trace method. The spectral and spatial distribution of radiant intensity is investigated. The optical and Splitting efficiency of the system at AM1.5 is 66.1% and 78%, alternatively. The total power generating efficiency of the system in theory is 18% with silicon solar cell with geometric concentration ratio 80. Beam Splitting can reduce the solar cell temperature and increase concentration ratio together with photoelectric conversion efficiency.

  • performance testing of a spectral Beam Splitting hybrid pvt solar receiver for linear concentrators
    Applied Energy, 2016
    Co-Authors: Cameron Stanley, Ahmad Mojiri, Mirza Rahat, Andrew Blakers, Gary Rosengarten
    Abstract:

    A novel spectral Beam Splitting photovoltaic/thermal (PVT) solar receiver for linear concentrators has been developed capable of generating high-grade thermal energy concurrently with electricity. This paper evaluates the initial field testing of this receiver which combines a selective absorption heat transfer fluid (Propylene Glycol) with a band pass optical filter to achieve efficient spectral Splitting. Wavelengths of light between 700nm and 1100nm are directed to the silicon PV cells, with the remaining wavelengths absorbed directly as heat. A prototype has been constructed and mounted to a parabolic trough concentrator with 42× geometrical concentration ratio. Results demonstrated considerable promise for this technique. High grade heat thermal efficiencies of 31% relative to the thermal Beam Splitting fraction were achieved at a receiver temperature of 120°C, with a total system efficiency of 50%. Electrical yields of approximately 3.8% relative to the total incident power were measured. While lower than expected we expect with minor modifications system efficiencies beyond 75% will be achievable.

    Abstract:

    To convert solar energy into electricity and heat simultaneously and efficiently we have been working on combining optical concentration with spectral Beam Splitting. Our systems can produce 150 degrees C heat while keeping PV temperatures below 60 degrees C, with over 75% efficiency.
