研究目的
Investigating the possibilities of flat-plate heat-sinks for passive cooling at concentration ratios within 2,000-10,000 suns in ultra-high CPV systems.
研究成果
The miniaturization of solar cells is crucial for adequate thermal management in ultra-High CPV systems. Flat-plate heat-sinks can effectively manage the thermal load for micro solar cells up to 10,000 suns, keeping cell temperatures below 60oC. Future work will include optical elements in the thermal modelling and address the electric-thermal modelling of different MJ solar cells.
研究不足
The study did not include finned heat-sinks and assumed adiabatic conditions for the borders of the flat heat-sink, which may not fully represent real-world scenarios. The thermal conductivities were set with no dependence on temperature variations.
1：Experimental Design and Method Selection:
A thermal 3D finite-element model was used to simulate the thermal behavior of an Aluminium flat heat-sink for ultra-High-CPV receivers.
2：Sample Selection and Data Sources:
A standard triple-junction GaInP/GaInAs/ Ge solar cell with an area of 1x1 mm2 was considered.
3：List of Experimental Equipment and Materials:
The receiver included layers of Ge, SnAgCu, Cu, AlN, Cu, Epo-tek, and Al with specified thicknesses and thermal conductivities.
4：Experimental Procedures and Operational Workflow:
Simulations were conducted for concentration levels ranging from 2,000 to 10,000 suns under Concentrator Standard Operating Conditions (CSOC).
5：Data Analysis Methods:
The heat transfer mechanisms and thermal resistances were analyzed using COMSOL Multiphysics? based on Finite Element Analysis (FEA).
