Abstract :
Hybrid metal oxide / polymer solar cells are one of the promising classes of Organic Photovoltaic (OPV) device and have been intensively studied for more than a decade because of the availability to control interface morphology for improving their performance. Several strategies have been reported to improve photovoltaic performance of metal oxide / polymer solar cells. This work discusses a range of new strategies which include, the use of metal oxide:carbon nanotube blend films and interface modifiers such as, Self-Assembled Monolayers (SAMs), dyes and insulating thin alumina layers. Further, the Time of Flight (TOF) photocurrent measurement technique has been employed as a tool to determine the hole-mobility in nanocomposite films of porous titanium dioxide and poly (3- hexylthiophene), with or without interfacial layer. This study concludes that the hybrid metal oxide / polymer composite is a good model system to study the effects of interfacial properties and film morphology on the performance of bulk hetero junction photovoltaic devices. Moreover, expertise gained with this hybrid systems has proved to be valuable in improving the performance of other PV systems.
