    摘要: 量測有機半導體銅酞菁(Copper Phthalocyanine,CuPc)在不同溫度下的白光吸收(absorption)與光致螢光(photoluminescence)的光譜變化,來探討CuPc在不同溫度下電子躍遷的狀況;並以應用在有機薄膜太陽能電池的考慮下,判斷溫度對CuPc有何影響。實驗發現,在溫度200K到400K之間,吸收光譜沒有明顯的位移以及強度變化;光致螢光光譜雖然沒有位移,但是強度會隨溫度降低而增強,同時伴隨一個聲子的光致螢光0-1峰也會更加明顯。因此由光譜推論CuPc在低溫的效能會降低。
    We measured the absorption and photoluminescence spectra of the organic semiconductor CuPc(Copper Phthalocyanine)under various temperatures to discuss that how temperature affects the situation of electrons transition and efficient of CuPc in organic thin film solar cells. The experiment result reveals that absorption spectra without peak shift and intensity change when increasing the temperature. Photoluminescence spectra also without peak shift but intensity increases with decreasing temperature. Simultaneously , the photoluminescence with a phonon involved is more obvious. From this observation, we conclude that the working efficient of CuPc in solar cells may decrease with decreasing temperature.
