Abstract:

Solar photovoltaic cells convert energy from the sun directly to useable electricity. With growing energy demands and the need to reduce our carbon emissions, solar cell technology is an attractive part of our renewable energy mix. While the most commonly deployed solar cells have 18% conversion efficiency, the thermodynamic limit is ~ 85%. I will give an overview of the research in the PV community aimed towards achieving ultimate efficiencies as well as reducing costs to help solar technology reach grid parity. I will also describe some of the work being done at McMaster University in this area, on Silicon-based multi-junction solar cells, where we have achieved record performance for this device category.
