Leveraging organic electronics as an accessible alternative to silicon semiconductors
Organic electronics, which use carbon-based semiconductors, present several advantages over traditional electronics that are silicon-based. While silicon semiconductors may be a tried and true, mature technology, some important factors make the use of silicon less favourable for emerging and more niche applications. Notably, electronic grade silicon is manufactured at extremely high temperatures, resulting in elevated fabrication costs and significant environmental implications. In addition, organic materials are inherently lighter, thinner and more flexible, rendering them of great interest for current and novel electronic applications.
Professor Benoît Lessard runs the Lessard Research Group, where he and his team, work diligently on developing active carbon-based materials that have a wide range of applications. Some of these applications include:
- Health tech, such as point of care diagnostics for the inexpensive and quick detection of narcotics or disease and wearable environmental sensors that detect carbon monoxide for first responders;
- Light emitting technology, such as flexible organic LED-based displays for phones or televisions and energy-efficient lighting solutions; and
- Sustainable and renewable energy, such as inexpensive solar power generation through organic photovoltaics that can be rolled up and taken travelling or made semitransparent and used as power generating window shades in sky scrapers.
While carbon-based semiconductors are not expected to displace silicon in computers or as grid power generation materials, they have the potential to disrupt markets and provide new opportunities for the growing internet of things. Exploiting these carbon-based materials provides a less expensive, more accessible and flexible alternative to traditional electronics, which the public can expect to see more over in the near future.
