研究目的
Investigating the capability of impinging jet cooling technique to maintain a triple junction solar cell temperature under recommended operating conditions and performing thermal stress analyses.
研究成果
The study demonstrated that jet impingement cooling effectively maintains the triple-junction solar cell temperature within recommended operating conditions, enhancing both thermal energy and electrical generation. Thermal stress was significantly reduced with increased cooling inlet mass flow rate. Configuration (A) showed superior performance in reducing cell temperature and thermal stress compared to configuration (B).
研究不足
The study focused on the thermal and structural performance of the solar cell under specific cooling conditions and did not explore the long-term durability or the impact of environmental factors other than temperature.
1：Experimental Design and Method Selection:
The study involved thermal modeling of high concentration ratio multi-junction solar cell under CR of 1000 using ANSYS-Fluent 18.2 software. A three-dimensional comprehensive thermal/structural model was developed to solve the conjugate heat transfer governing equations of two different impinging jets heat sink designs integrated with the TJ cell.
