利用酞菁铅（PbPc）和富勒烯（C（60））共沉积的i-夹层制备了对1050 nm具有近红外（NIR）灵敏度的有机p-i-n太阳能电池。外量子效率和转换效率的近红外光分别达到43%（860 nm）和2.3%。共沉积的i-夹层被示出具有三个单独的纳米结构组件，每个组件对电池的操作做出贡献。这些是通过非晶C（60）的电子传输，通过PbPc的H-聚集体的空穴传输，以及通过近红外光在PbPc的J-聚集体位点产生载流子。(c)2011年美国物理学会。[doi：10.1063/1.3534804]
Organic p-i-n solar cells having near infrared (NIR) sensitivity to 1050 nm were fabricated using a codeposited i-interlayer consisting of lead phthalocyanine (PbPc) and fullerene (C(60)). The external quantum efficiency and conversion efficiency for NIR light reached 43% (860 nm) and 2.3%, respectively. The codeposited i-interlayer was shown to have three separate nanostructural components each making a contribution to the operation of the cell. These were electron transport through amorphous C(60), hole transport through the H-aggregates of PbPc, and carrier generation by NIR light at the J-aggregate sites of PbPc.
