Conductivity and work function of the conductive polymer, poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), has been investigated for a top electrode of the solution-processed organic solar cells (OPV). It has been found that both conductivity and work function could be changed by adjusting the mixing ratio of different commercial grade PEDOT:PSS such as PH 1000 and AI 4083. A 2:1 vol ratio of PH 1000 and AI 4083 mixture provided the conductivity of 443 S/cm (corresponding sheet resistance (R_sh) of 260 Ω/sq) and the work function of 5.09 eV. Therefore, this PEDOT:PSS mixture may work as both a hole transport layer (HTL) and anode electrode of the OPV. For verifying, all-solution-processed bulk heterojunction (BHJ) inverted OPVs were fabricated using developed PEDOT:PSS conductive polymers as both HTL and anode top electrode. Under the AM1.5G spectrum calibrated 100 mW/cm² illumination, fabricated all-solution-processed OPV provides a best photo-conversion efficiency (PCE) of 2.04% accounted from an open circuit voltage (V_oc) of 576 mV, a short circuit current (J_sc) of 6.91 mA/cm², and a fill factor (FF) of 51.2%. In addition, the final OPV exhibits semitransparency due to no metal electrode on top and transparency of the conductive polymer.

对于溶液加工的有机太阳能电池（OPV）的顶部电极，已经研究了导电聚合物聚（3,4-乙撑二氧噻吩）-聚（苯乙烯磺酸盐）（PEDOT：PSS）的电导率和功函。已经发现，通过调节不同商业级PEDOT：PSS的混合比例（例如PH 1000和AI 4083），可以同时改变电导率和功函数。PH100​​0和AI 4083混合物的体积比为2：1可提供443 S / cm（对应的薄层电阻（R _sh）的260Ω/ sq）和5.09 eV的功函数。因此，此PEDOT：PSS混合物可以同时用作空穴传输层（HTL）和OPV的阳极。为了验证，使用开发的PEDOT：PSS导电聚合物作为HTL和阳极顶部电极，制造了全溶液处理的本体异质结（BHJ）倒置的OPV。在AM1.5G光谱校准的100 mW / cm ²照明下，制造的全溶液处理过的OPV的开路电压（V _oc）为576 mV（短），提供了2.04％的最佳光转换效率（PCE）。电路电流（J _sc）为6.91 mA / cm ²，填充因子（FF）为51.2％。另外，由于顶部没有金属电极和导电聚合物的透明性，最终的OPV具有半透明性。
