矽基太陽電池有著高效率、豐富來源等優點；而有機太陽電池可以利用低溫、低成本之溶液製程以及擁有捲對捲的拓展性之優勢，結合以上兩種系統的太陽電池，即是有機無機混成太陽電池。在無機的矽基板以及有機的共軛高分子材料基礎下，不但可以有效簡化製程手法，進而能大幅降低整個太陽電池的製程成本，但依舊可維持高效率之特點。

在本論文中，我們開發出一種利用共溶劑混藥方式，去配製具有強大拉電子能力的F4TCNQ摻雜於寬能帶的螢光高分子PFO中，此P型的有機層被旋塗在矽奈米線跟TAPC之介面，用以當做載子複合層且可拉低螢光高分子的費米能階，並且我們透過紫外光光電子能譜儀以及X-ray光電子能譜儀的量測，可以觀察到此P型的有機層中的F4TCNQ分布，是透過垂直性相分離的方式，呈現一種空間上梯度式摻雜，導致越靠近矽奈米柱處摻雜的F4TCNQ就越多，也就越呈現P型，此現象不但造成矽基板與P型有基層接面處的能帶彎曲，也使得電洞更容易因能障降低而傳遞到電極，因而提升開路電壓與填充因子，其元件轉換效率可達 13.6%。

Silicon solar cells have the advantages of high efficiency and abundant resources on earth.And organic solar cells can be fabricated in low temperature,low-cost solution processes and also has roll-to-roll scalability.Combining the advantages of these two material systems,hybrid solar cells based on organic conjugated polymers and inorganic silicon is a promising alternative to simplify the fabrication processes and reduce the cost,while maintaining a high PCE.

In this study,we introduce a co-solvent method to dope a wide band gap poly(9,9-dioctyfluorenyl-2,7-diyl) (PFO) fluorescent polymers with a very efficient electron acceptor tetrafluorotetracyanoquinodimethane(F4TCNQ).The p-doping layer was deposited onto and between 1,1-bis[(di-4-tolylamino)phenyl]cyclohexane(TAPC)layer and SiNWs by the solution processing method in order to form a recombination layer and lower Fermi level of fluorescent polymers.

Furthermore,Ultraviolet Photoelectron spectroscopy (UPS) and X-ray Photoemission spectroscopy (XPS) confirms that F4TCNQ is spatially graded doping via vertical phase separation in this p-type doping layer.The nearer to SiNWs,the more F4TCNQ is doped, which let p-type layers become more p-type.

The power conversion efficiency reaches a record 13.6%, which is largely ascribed to the band bending between n-type silicon and p-doping layer interface.Consequently,holes can conduct to electrodes more easily by lowering energy barriers,which boost the open-circuit voltage and fill factor.
