隨著人類生活的進步，對於能源的需求是愈來愈高。但地球所蘊含之能源相當有限，因此各種替代的再生能源便在這種情況下逐漸發展出來，其中尤以太陽能為代表。太陽能發電是利用半導體材料所製作出的太陽能電池，將光能轉換成電能。而聚光型太陽能發電系統有別於傳統面板式之構造，主要為導入光學聚光模組以提升其輸出功率。然在聚光條件下，元件的溫度會快速的上升；換言之，隨著元件溫度的升高，其光電轉換之效能亦會隨之下降。也因此熱能管理(Thermal Management)成為聚光型太陽能電池封裝的重要課題。本計畫擬建立一套設計聚光型太陽能電池模組散熱結構之方法，透過有限單元套裝軟體ANSYS®建立聚光型太陽能電池封裝之基準熱傳分析模型，代入估算之晶片發熱功率進行分析後，經由量測實驗驗證有限單元分析的可靠性與估算晶片發熱功率之準確性。接著以此基準熱傳分析模型為基礎，進一步對模組散熱結構進行參數化分析，深入探討不同幾何外形與參數等對於散熱效能之影響。藉由分析結果亦可進一步延伸至聚光型太陽能電池封裝的散熱結構之最佳化設計，對於未來太陽能能源發展有著相當大的助益。 ; The demand for energy resources to improve our quality of life continues to increase. However, the prices of Fossil Energy keep going up and the resources are limited. Therefore, more and more reusable energy resources are being developed. The foremost among these reusable energy resources is solar energy. A solar cell, powered by solar energy, uses semiconductors to transform light into electric power. The difference in structure between high-concentration photovoltaic (HCPV) solar cell system and traditional solar cell system is the usage of concentrated-light module to enhance the optic-electric transition efficiency. In general, under concentrated-light operation condition, the device temperature rises quickly. In other words, due to a decrease in open-circuit voltage of increasing temperature, the system output power or energy-conversion efficiency decreases with the increasing temperature of the cell incorporated within the system. Therefore, thermal management has been an important issue for HCPV solar cell system. In this proposal, it suggest to establish a detailed finite element model of the HCPV solar cell module as a benchmark using ANSYS® finite element analysis program. The finite element analysis can simplify and quickly resolve the thermal management problem of the HCPV solar cell package. Besides, the indoor and outdoor experiments are also performed to validate the benchmark finite element model that uses predicted thermal dissipation power. Based on the established benchmark finite element model, the influences of various design parameters for heat dissipation structure of HCPV solar cell module will be studied thoroughly. Through this manner, the thermal performance and optimization of HCPV solar cell package can be obtained. ; 研究期間 9801 ~ 9812
