以低成本、可在低溫下合成的濕式化學方法來製作可有效利用綠色能源的光伏元件，例如混和型太陽能電池為現今具潛力的研究之一。本研究以導電高分子材料poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate)(PEDOT:PSS)與n型矽奈米線複合並將其應用於太陽能電池，由於材料本身性質，其形成之異質結構以及異質接面在元件應用方面具一定優勢。然而，PEDOT:PSS本身具有非常低之導電率，約為0.2至10 S/cm，如何提升PEDOT:PSS之導電率以增進太陽能電池之效率為本研究之主要課題。因此，本實驗以表面處理法與混摻法改質PEDOT:PSS。第一階段以乙二醇(ethylene glycol)作為添加劑，結果可得到在添加7wt%乙二醇的PEDOT:PSS具有最佳的導電率，其導電率為938 S/cm。接著將此樣品在攝氏90度下進行熱攪拌之處理，可將導電率提升至1228 S/cm。改質後之PEDOT 具優異的光學性質以及電性，且將其應用於太陽能電池後可使效率提升至12.42%。

A potential alternative photovoltaics device, hybrid solar cells (HSC), is getting more interest due to inexpensive routes in low-temperature conditions, convenience wet methods, and sounds efficient to provide clean energy from incoming light. Generally, the arrangement of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) organics and n-type crystalline silicon nanowires (SiNWs) were proposed as the option in junction structures by considering the superiorities reliability and both materials advantage properties. However, tune up the conductivity of PEDOT:PSS is essential to improve arranged cells due to low-conductivity nature bring about 0.2-10 S/cm. The improvement of PEDOT:PSS electrical character is achieved by co-solvent mixing and hot-stirring treatment. Pristine PEDOT:PSS conductivity is optimized to more than 102 orders achieving 938 S/cm with 7 wt% ethylene glycol (EG)-0.1 wt% Zonyl FS300 surfactant composition. Achieved value can be further elevated up to 1228 S/cm by additional hot-stirring treatment at 90°C. Tremendous electrical and optical aspects with preferable treatments offer several advantages in fabricated cells including performance and elevated efficiency of 12.42%.
