The patterned Indium Tin Oxide (ITO) Glass subtrates are part of Ossila's award winning prototyping platform. ITO is both conductive and transparent, which makes it an ideal material for use with optoelectronic devices such as photovoltaics and OLEDs.
As thin film technology improves, the active areas of device pixels increase in size. The 25mm square substrates have been designed to help the community take the next step in scaling up active areas. When combined with our deposition masks, these substrates allow four pixels per substrate, with active areas of 48mm2 each.
The following video shows the fabrication and testing of devices using the PV and OLED device prototyping substrate system and a glove box.

Making OLEDs and OPVs: A Quickstart Guide
Organic photovoltaic cells (OPVs) or organic light emitting diodes (OLEDs) can be easily manufactured using Ossila's pre-patterned ITO substrates and a few simple spin coating and evaporating steps. This article, and its companion video, will guide you through this process and offer hints and tips for how to get the best devices.
