The Quantum Dot-sensitized Solar Cells (QDSSCs): A Review on Recent Achievements (2010-2021)

Abstract

Over the past few decades, quantum dots sensitized solar cells (QDSSCs) have attracted significant attention due to the quantum dots sensitiser's unique properties, including, its non-precious synthesis, size-tuneable bandgaps; excellent photostability, the ability to generate multiple excitons, and high absorption coefficient that led possible to increase power conversion efficiency (PCE) to more than 15% due to their higher molar extinction coefficient and tuneable photo-response. This review article outlines a comprehensive overview of the development of the performance of QDSSCs including their components fabrications and highlights the challenges and limitations of the QDSSCs' components such as narrow absorption areas and the charge recombination happening at the photoanode/electrolyte interfaces and discusses the prospects for the development of highly efficient and stable QDSSCs.
