ZnO Nanowire Arrays for Enhanced Photocurrent in PbS Quantum Dot Solar Cells. (26th February 2013) - Jean, Joel
Abstract Vertical arrays of ZnO nanowires can decouple light absorption from carrier collection in PbS quantum dot solar cells and increase power conversion efficiencies by 35%. The resulting ordered bulk heterojunction devices achieve short‐circuit current densities in excess of 20 mA cm−2 and efficiencies of up to 4.9%.
