Conjugated Polymers as Hole Transporting Materials for Solar Cells

In principle,conjugated polymers can work as electron donors and thus as low-cost p-type organic semiconductors to transport holes in photovoltaic devices.With the booming interests in high-efficiency and low-cost solar cells to tackle global climate change and energy shortage,hole transporting materials(HTMs)based on conjugated polymers have received increasing attention in the past decade.In this perspective,recent advances in HTMs for a range of photovoltaic devices including dye-sensitized solar cells(DSSCs),perovskite solar cells(PSCs),and silicon(Si)/organic heterojunction solar cells(HSCs)are summarized and perspectives on their future development are also presented.

以CuPc为空穴传输层的染料敏化异质结电池的特性研究

制备以酞菁铜CuPc为空穴传输层,有机染料-二氢吲哚D102(C37H30N2O3S2)为敏化染料的染料敏化异质结电池DSH(Dye-sensitized heterojunction solar cells)。研究不同厚度CuPc空穴传输层:40 nm、80 nm和120 nm的电池的性能,得到在其厚度为40 nm时,电池的Jsc=248.3μA/cm2,Voc=0.61V,=0.042%(80 mW/cm2氙灯测试)。对比采用I3-/I-氧化-还原对为液态电解质的染料敏化TiO2纳米晶太阳电池,分析以CuPc为空穴传输层的DSH电池效率较低的原因。
