Research Overview

Semiconductors are key enablers of the Information Age we live in. Firstly, they are essential constituents of the numerous electronic and optoelectronic devices (e.g., computers, displays, imagers, sensors) that continue to improve our quality of life whilst sustaining global economic and societal development. Additionally, semiconductors are essential in energy harvesting technologies such as photovoltaics, which are key to tackling the rising energy demand and climate change.

The Pecunia Research Group – Sustainable Optoelectronics investigates emerging, environmentally friendly, printable semiconductors (e.g., organic semiconductors, lead-free perovskite derivatives, carbon nanotube networks, metal-oxide semiconductors), and their applications in electronics, optoelectronics, and photovoltaics. Not only are these semiconductors environmentally benign, but they can also be processed in the form of inks, at low temperatures, and on flexible, low-cost plastic substrates. This allows their use in the fabrication of electronic, optoelectronic, and photovoltaic devices with inexpensive, facile processes—for instance, inkjet printing, which is the same basic technology used to print documents in our homes.

Moreover, the unique properties of these printable semiconductors open up new application space that is currently inaccessible by chip-size electronics/optoelectronics—e.g., point-of-use, flexible devices in unique form factors for energy harvesting, smart homes, smart packaging, smart cities, and healthcare.
