Abstract
Description
b表面をクエンチするSiO2についての結果を用い、無限表面再結合速度を仮定する。LD PPEI=2.5±0.5 μmにつながる結果は、溶媒蒸気支援アニーリング中のクエンチャー拡散及びモロフォルジーの変化に影響されそうである。
c光干渉効果は考慮していない。
光電池装置は、ガラス基板上に予め被覆した1300Å厚のインジウム錫酸化物(ITO)層上に作製した。溶液洗浄したITO表面を堆積前に紫外線/オゾンに曝した。フォレスト(Forrest)のChem.Rev., 97, 1793 (1997年)に説明されているように、有機源材料:CuPc,C60,2,9-ジメチル-4,7-ジフェニル-1,10-フェナントロリン(BCP)を使用前にも、熱勾配昇華によって精製した。全ての有機材料は、層厚及び堆積速度を決定するために、クオーツ結晶モニターを用いて高真空(<10−6Torr)下で熱的に蒸発した。膜厚モニターを用いて重量%で測定したCuPcとC60の混同比は特にことわりがなければ、1:1に固定していた。Ag陰極を1mm直径開口を有する金属シャドウマスクを介して堆積した。暗状況(ダーク)の下でかつフィルタされたXeアークランプ源からAM1.5G疑似太陽スペクトルの照明下で電流密度−電圧特性(J−V)を測定した。較正された電力メーターを用いて照度を測定した。
