Surface and Interface Effect of Durable and Efficient Polymer Solar Cells |
| 초록 |
we devised novel process of stamping transfer technique of an bulk-heterojunction active layer with help of UV-curable resin-coated polycarbonate (UV-PC) film. And a patterned conducting IZO film with well-ordered periodic dot-structures with 50 nm or 200 nm deep features has been constructed by nanoimprinting technique as the anode of an photovoltaic device. The highly ordered 2D-dot nano-patterned anode can enhance the device performance due to the large interfacial area between both of the electrodes and the active layer. Also, the bilayer active film with a concentration gradient has been successfully fabricated via solution process for the first time. The concentration variation has been confirmed by the Auger spectroscopy. The novel device showed an enhanced photocurrent density and power conversion efficiency compared to those of the BHJ PV prepared under the same fabrication condition. |
