Stability of Bulk-Heterojunction Blends for Solar Cell Applications
Polymer solar cells are a promising alternative to more traditional silicon solar cells. This is mainly due to the good solubility of organic semiconductors, which makes it possible to produce large-scale and mechanically flexible devices with roll-to-roll processes. To be able to fully utilise this promising technique the stability of the materials, used in these devices, must be guaranteed. T...

A series of low band gap copolymers consisting of electron-accepting pyrazino[2,3-g]quinoxaline (PQx) and an electron-donating indolo[3,2-b]carbazole and thiophene units have been designed and synthesized by Stille coupling polymerization. Their optical and electrical properties could also be facilely fine-modulated for photovoltaic application by adjusting the donor/acceptor ratios. UV-vis mea...
متن کاملInterdiffusion of PCBM and P3HT Reveals Miscibility in a Photovoltaically Active Blend
Developing a better understanding of the evolution of morphology in plastic solar cells is the key to designing new materials and structures that achieve photoconversion effi ciencies greater than 10%. In the most extensively characterized system, the poly(3-hexyl thiophene) (P3HT):[6,6]-phenyl-C 61 -butyricacid-methyl-ester (PCBM) bulk heterojunction, the origins and evolution of the blend mor...
متن کاملEffect of Seed Layer on the Morphology of Zinc Oxide Nanorods as an Electron Transport Layer in Polymer Solar Cells
Zinc oxide has been considered as a promising semiconductor material for fabrication of transparent conductive oxides (TCOs), electronic devices, optoelectronics, and solar cells. Among the various morphologies of zinc oxide, nanorods are more widely used because of the ease of synthesis and providing a direct path for the transport of charge carriers. The electrochemical deposi...
