Abstract
The Perovskite Solar Cell has garnered a fair amount of excitement over the past few years that can be attributed to the high efficiencies obtained using very simple solution phase deposition processes. Most of the research has focused on high efficiency and durable devices using techniques that won’t scale such as spin coating in highly controlled environments. The perovskite material itself is very defect tolerant and as such lends itself extremely well to solution phase deposition over very large areas. The other thin films within the device, namely the hole transport and electron transport materials (HTM and ETM) can be very low cost metal oxides. The work in this presentation outlines techniques to mount these three layers onto a roll-to-roll platform running at high speeds in ambient environments. Devices are built on a flexible plastic substrate and tested using LIV measurements. The morphology of the thin films are characterized using XRD, SEM and UV-Vis. Stability measurements of the devices are also included in the talk.
