無機二氧化鈦奈米纖維和有機共軛高分子對聚噻吩運用於新型混成太陽能電池。無機二氧化鈦奈米纖維具有任意分布的一維奈米絲結構，不僅提供大量的異質接面表面積，且具有連續的傳導路徑供電子傳遞，對聚噻吩具有光電活性且被用於傳遞電洞，對聚噻吩經由溶劑塗佈法沉積在二氧化鈦奈米纖維上，藉由控制不同濃度的溶劑，則可控制沉積厚度。

　　上電極則利用銀奈米漿料塗佈於主動層，銀奈米漿料可深入由二氧化鈦無機奈米纖維和對聚噻吩所形成的主動層，透過適當熱處理後，由銀奈米顆粒形成深入結構之連續電極，此連續電極增加與對聚噻吩的接觸面積並增強電子的收集與傳遞。藉由改變銀奈米漿料的沉積量，整理出所改變的光電性質，包含：開路電壓、短路電流密度、分流電阻與串聯電阻等。

　　結果指出，銀奈米漿料透過深入結構的連續電極成功地增強電荷的收集，然而，連續電極亦部分阻礙了入射光的吸收，文中詳述其相關細節，並歸納出由無機二氧化鈦奈米纖維、有機共軛高分子對聚噻吩和銀穿透電極所組成的最佳化新型混成太陽能電池。

　　A novel hybrid solar cell was fabricated by the uses of the nanostructured inorganic titania nanofibers and the organic conjugated poly(3-hexyl thiophene) (P3HT). Electrospun titania nanofibers constructed a randomly orientated fiber scaffold that provided not only the large surface area as the heterojunction interface, but also the continuous pathway for the electron collection. P3HT served as the photovoltaic active and hole transfer material was deposited via the solution casting process that generated a conformal P3HT outer layer with controllable thicknesses. Upper electrode was established by utilizing a silver nanoparticle paste which was introduced also by a solution process, followed by a post heat treatment that converted the silver paste to the conductive silver material. More importantly, the silver paste was designed to penetrate into the P3HT/titania fiber scaffold that generated more contact with the P3HT and enhanced the hole collection and transfer. By alternating the silver paste depositions, the photovoltaic performances, including the open circuit voltage, the short circuit current density, the shunt resistance and the series resistance, were carefully investigated. Results indicated that the silver paste successfully improved the charge collection; however the penetrated electrode also partially blocked the incident light with the P3HT layer. Detailed investigations were carried out in this research work, and the optimized photovoltaic device based on the nanostructured P3HT/titania nanofiber and the silver penetrated electrode was presented.
