Not all incident light of spectrum is absorbed by solar cell and transformed to current completely in the fact. The maximum efficiency of the single solar cell is about 25% which is almost achieved to the theoretical value. The thesis mainly studies on spherical solar cell combining with reflector and mentions the way that can increase the power of electricity output. It not only increases the region of incident light, but also increases the power of electricity output at the same time if designing the reflector system of spherical solar cell has be done. Design the better reflector (Type B and Type C) geometrically, calculate the Shape Factor of incident light to the Si spherical and the area of incident light with mathematics in the thesis. The two new types (Type B and Type C) of the reflector system are increased the region of incident light by using the incident light which reflects it to the bottom of the spherical. The incident light of region can be reached approximating 100% as the incident light is 90°.目錄 ----------------------------------------------------Ⅲ 圖目錄 --------------------------------------------------Ⅴ 表目錄 --------------------------------------------------Ⅶ 誌謝 ----------------------------------------------------Ⅷ 論文摘要(中文) ------------------------------------------Ⅸ 論文摘要(英文) ------------------------------------------Ⅹ 符號說明 ------------------------------------------------ⅩⅠ 第一章 緒論 --------------------------------------------------------------------1 1.1 前言 ---------------------------------------------------------------------------1 1.2文獻回顧 ----------------------------------------------------------------------3 1.3研究動機與目的 -------------------------------------------------------------4 1.3-1 研究動機 --------------------------------------------------------------- 4 1.3-2 研究目的 --------------------------------------------------------------- 4 第二章 原理 ----------------------------------------------------------------------5 2.1 太陽能光電池介紹 ---------------------------------------------------------5 2.2太陽能光電池發電原理 ----------------------------------------------------5 2.2-1光伏特效應 ----------------------------------------------------------------7 2.3太陽能電池基本結構與種類 ------------------------------10 2.4太陽電池效率的基本限制 --------------------------------12 2.5超低成本太陽電池(矽球太陽能電池) ----------------------16 2.5-1矽球太陽能電池製造方法 ----------------------------------------------17 第三章 矽球太陽能電池反射板設計與分析---------------------18 3.1矽球太陽能電池反射板設計原理 --------------------------18 3.2設計一 ------------------------------------------------20 3.3設計二 ------------------------------------------------21 3.4設計三 ------------------------------------------------21 第四章設計結果分析----------------------------------------23 第五章 結論與探討 ----------------------------------------26 第六章 未來展望 ------------------------------------------28 參考文獻 -------------------------------------------------29en-US矽太陽能電池反射板能量輸出功率SiSolar cellreflectorenergypower outputthesis
