Abstract This dissertation begins with a general introduction of solar energy. The state-of-the-art development of various solar cell technologies is reviewed. Critical factors limiting the solar cell device performance are highlighted and strategies for further device improvement are demonstrated by giving recent examples from literature. In this work, we develop solutionprocessed photovoltaic devices using lead sulphide quantum dots and high surface area porous titanium dioxide electrodes. Both the materials and device structures are investigated and optimized systematically in respect of QD synthesis, post-synthetic modification and device fabrication, leading to an improvement of quantum dot based solar cells power conversion efficiency (PCE. |
