In December 2010, I completed a bachelor’s degree in Chemistry at McGill University. During this degree, I had the opportunity to work in three different research groups: Prof. Tito Scaiano’s group at University of Ottawa (Summer 2008, photochemistry), Prof. Jean-Luc Meunier and Prof. Sylvain Coulombe’s group (Summer 2009, heteronanocomposites) and Prof. Eric Salin’s group (Summer and Fall 2010, lab-on-a-chip applications), both at McGill University.

In 2011, I joined (again!) Prof. Meunier and Prof. Coulombe’s group for a M. Eng. degree. My project consists in developing new heteronanocomposites for the use in photovoltaic cells. It has been shown that CdSe nanoparticles deposited on carbon nanocups can be used as a photoelectrode, absorbing photons to generate electrons and thus, form a photocurrent in a photoelectrochemical cell. For our work, carbon nanotubes synthesized by chemical vapor deposition (CVD) directly on stainless steel meshes are decorated by CdSe nanoparticles produced by laser ablation (LA). Both methods chosen, CVD and LA, offer the advantage of being simple dry methods, where there is no need to deal with solvents and large amounts of waste. Work is still on-going to characterize the photoresponse of this novel electrode.
