中文摘要：本文主要研究了聚3,4-二氧乙烯噻吩:聚苯乙烯磺酸（PEDOT:PSS）的功函数对杂化光伏电池性能的影响。我们把氯铂酸溶液添加到PEDOT:PSS溶液中，研究不同体积比的氯铂酸溶液对杂化太阳能电池性能的影响。

同组研究数据表明，铂（Pt）纳米颗粒掺杂可以提高PEDOT:PSS的功函数，我们绘制了Si/PEDOT:PSS界面能带示意图，PEDOT:PSS的功函数（Φb）增大，会导致界面处产生更大的内建电势（Vbi），进而导致器件的开路电压（Voc）增大。分析杂化太阳能电池的J-V特性曲线发现，随着掺入氯铂酸溶液体积比的增大，基于Si/PEDOT:PSS杂化光伏电池的开路电压（Voc）、填充因子（FF）和光电转换效率（PCE）先逐渐增加，当氯铂酸溶液体积比达到15%时，Voc达到0.550V，FF达到65.8%，PCE达到10.35%的最大值，当氯铂酸溶液体积比进一步增加时，Voc和FF都开始降低，导致器件性能降低，当氯铂酸溶液体积比达到25%时，PCE降到9.74%。另外，随掺入氯铂酸溶液体积比的增大，短路电流密度（Jsc）一直保持增长趋势。我们把Si/PEDOT:PSS杂化光伏电池性能的变化归因于Pt纳米颗粒掺杂提高了PEDOT:PSS的功函数。

Abstract：In this paper, the effects of the work function of poly (3,4-dioxylene) thiophene: polystyrene sulfonic acid (PEDOT:PSS) on the performance of hybrid photovoltaic cells were studied. We added chloroplatinic acid solution to PEDOT:PSS solution to study the effect of different volume ratio of chloroplatinic acid solution on the performance of hybrid solar cells.

The same group of research data show that platinum（Pt）nano-particle doping can

improve the PEDOT:PSS work function. We plotted the Si/PEDOT:PSS interface band diagram. The increase in the work function (Φb) of PEDOT:PSS results in a larger built-in potential (Vbi) at the interface, which in turn increases the open circuit voltage (Voc) of the device.

The J-V characteristic curve of the hybrid solar cell was analyzed. The open circuit voltage (Voc), fill factor (FF) and the filling factor (FF) of the PSS hybrid photovoltaic cell were measured with the increase of the volume ratio of the chloroplatinic acid solution Photoelectric conversion efficiency (PCE) first gradually increased, when the volume ratio of chloroplatinic acid solution reached 15%, Voc reached 0.550 V, FF reached 65.8%, PCE reached the maximum value of 10.35%. When the volume ratio of chloroplatinic acid solution increased further, both Voc and FF began to decrease, leading to reduced device performance. When the volume ratio of chloroplatinic acid solution reached 25%, PCE decreased to 9.74%. In addition, with the incorporation of chloroplatinic acid solution volume ratio increases, short-circuit current density (Jsc) has maintained an increasing trend. We believe that the change of performance of Si/PEDOT:PSS hybrid PV cell is attributed to the increase of PEDOT:PSS work function due to Pt nano-particle doping.
