Roll-to-Roll Printing to Fabricate Single Strip and Large Panel of Thin Film Photovoltaics. (GRANT11999463) DURIP
Abstract
In this DURIP grant, funds will be provided for a benchtop slot-die coater that will be modified to allow real time x-ray morphological characterization of printed thin film photovoltaics. The Russell group is proposing the modification of a benchtop roll-to-roll (R2R) processing unit that will be used to characterize thin films of organic and perovskite photovoltaic devices in situ as the active layers of the devices are prepared. Based upon preliminary studies, using a less-than-optimized unit, the Russell group has developed the knowledge to design and construct an optimized unit that can be transported to any synchrotron facility or suitable laboratory x-ray unit for the structural characterization of thin films as they are processed in real time. This will provide a one-of-a-kind facility that will enable the correlation of structure development in thin films on flexible substrate as the film is being formed from solution. While initially designed for photovoltaic applications, the on-line, in situ device will be of general use in the characterization of any thin filmsthat can be processed onto a flexible web and will represent a quantum leap in the optimization of thin film structure and structure evolution.
