研究目的
To propose a novel concentrating assembly design for CPV that is able to handle multiple solar cells, without affecting their size, using single solar concentrator.
研究成果
The proposed multicell concentrating assembly (MCA) design reduces the overall cost of the system and the assembly and alignment efforts during CPV module fabrication. The system showed 100% power output for angular deviations up to 1°, as designed. However, the system showed maximum capability of handling 6.5° angular deviations.
研究不足
The machining method of fabrication is an expensive fabrication technique, and that is why smaller concentration ratio was chosen at the start to keep the overall cost minimum.
1：Experimental Design and Method Selection:
The design is based upon the Cassegrain arrangement of two parabolic concentrators, with the intention of achieving the area concentration.
2：Sample Selection and Data Sources:
The design parameters associated with the sizing of primary parabolic reflector are given.
3：List of Experimental Equipment and Materials:
Primary and secondary reflectors are machined from aluminum blocks. The multi-leg homogenizer was fabricated in the form of four symmetrical pieces which were joined together to form a single unit.
4：Experimental Procedures and Operational Workflow:
The developed CPV module was mounted onto the top frame of solar tracker.
5：Data Analysis Methods:
The performance of MCA was tested for parallel rays or rays with smaller deviations.
