ZIF-derived carbon/molybdenum disulfide composites as a counter electrode for dye-sensitized solar c
Exploring the low-cost and effective Pt-free catalysts is of particular significance for the development of dye-sensitized solar cell (DSSC).Transition metal sulfides (TMSs) have been considered as pr
Phosphorus doped tungsten-based composite material as the counter electrode for dye-sensitized solar
WS2 and WO3 are common catalysts in the field of electrocatalysis and are often used as CEs.However,scarce active sites and poor conductivity make their catalytic activity unsatisfactory.This work int
Nickel modified nitrogen-doped carbon composites as high-efficiency electrocatalysts for triiodide r
The development of an efficient and low-cost synthesis method to prepare highly stable non-noble metal counter electrode (CE) electrocatalysts for dye-sensitized solar cells (DSSC) is a crucial issue.
CZTSSe太阳能电池的背界面接触质量在制备高性能器件中具有非常重要的作用.Mo背电极与吸收层发生化学反应和背界面的严重复合问题仍然是研究的重点.当在背电极处引入合适厚度的高功函MoO3界面层后,高功函的MoO3抑制吸收层与Mo反应,器件的微观结构发生变化,MoSe2厚度显著降低,吸收层底部孔洞明显减少.同时,吸收层与背电极能带匹配得到优化,形成高质量的背建电场,提高载流子驱动力.最终器件转换效率

量子点敏化太阳能电池具有工艺技术简单、转换效率高等优点,已成为最具产业化潜力的新型电池[1,2].然而,量子点敏化太阳能电池的电荷传输性能依旧影响光电性能.虽然纳米阵列结构能够提升电荷传输速度,但是其光吸收性能不足,无法获得最佳的电荷产生量[3-5].因此,如何设计优化量子点敏化太阳能电池中的纳米阵列结构,是提升电池光电转换效率的关键因素.本研究工作通过多步阳极氧化法制备锥形竹节状TiO2纳米管阵
Cathode buffer layer interface modification is a commonly used strategy to prepare high-efficient organic solar cells (OSCs).Non-fullerene OSCs based on PM7∶ IT-4F were prepared and modified with PFN-
与台湾交通大学许千树课题组共同开发新型小分子PAS[1].在本研究中,利用UV-vis测试SnO2、PAS和SnO2∶PAS薄膜的紫外-可见吸收光谱和透射光谱(如图1).图1(a)为通过密度泛函理论(DFT)计算的PAS的最优构象以及LUMO和HOMO能级的电子云分布,可以看出在小于300 nm处的特征吸收是由磺酸基到吡啶环的n-π*跃迁引起的.在300-350 nm范围内尾端的吸收是由于极化跃迁
对于有机太阳能电池,在加热条件下或者在太阳光辐射下电池温度升高,导致光活性层形貌发生改变,进而导致有机太阳能电池器件性能的急剧下降.对于提高活性层形貌稳定性的需求,我们采用在活性层引入可交联的共轭有机半导体的方法.基于此,我们使用了一种新型的共轭小分子光引发交联剂(DTODF-4F).这个小分子共轭核心为具有优异的光电性能的芴单元.另外,在芴结构单元接枝可交联的两个环氧基团.环氧基团可以在光引发剂
The OSCs with high PCE and good thickness tolerance are essential for large-scale production.In this work,ternary OSCs are fabricated with PM6∶BTP-4F-12 as host system and IT-M as third component.By f
