Light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs) are used widely in solid state lighting, electronic displays, bio-imaging, and photovoltaic (PV) applications.  A cheaper, more efficient LED device can impact multiple markets.  Some of the primary applications include television displays, mobile device displays, medical applications, solid state lighting, and energy applications.


Typically, thin film optoelectronic devices, such as LEDs and PVs, are configured with a layered structure. This includes a photoactive (either light emitting or light harvesting) layer sandwiched between charge transport layers that contact with electrodes.  These charge transport layers play a crucial role in efficiency of the entire device.

This technology uses perovskite materials to create cost effective, efficient charge transport layers.
