Public Lecture:"Emerging Opportunities for Black Phosphorus in Energy Applications"

Professor Shu Ping Lau, Hong Kong Polytecnic University 

 
 
As a rising star in the family of two dimensional (2D) materials, black phosphorus (BP) has recently attracted tremendous attention all over the world and demonstrated great potential in energy applications owing to its direct and narrow bandgap, high carrier mobility and theoretical capacity, as well as anisotropic structure. Solution exfoliation of BP reveals superior advances when compared with mechanical exfoliation [1]. Remarkably, liquid-phase exfoliated BP flakes and quantum dots (QDs) exhibit exciting properties in batteries, solar cells, electronic, and optical devices. The exfoliation of BP in diverse solvents have been demonstrated. The solution exfoliated BP flakes can be an effective electron transport layer in organic photovoltaics (OPVs)[2]. The BP QDs can be incorporated in the active layer of OPV to boost its power conversion efficiencies [3]. Furthermore, it can also enhance the performance of Li-S batteries significantly[4].
