Abstract:

Organic-inorganic hybrid solar cells, which combine the advantages of conjugated polymers and inorganic nanocrystals, have attracted a lot of attention and been extensively studied in recent years. Cd-based compound nanocrystals, which were the first inorganic acceptor materials used in hybrid solar cells, have many advantages, such as easy synthesis, controllability of the size and morphology, high charge-carrier mobility, and high stability. This article reviews the structure and working mechanism of organic-inorganic hybrid solar cells, and analyzes the three main factors that have important influences on the power conversion efficiency (PCE) of hybrid solar cells: the open circuit voltage (Voc), short circuit current density (Jsc), and fill factor (FF). We also summarize the recent progress of Cd-based compound nanocrystal-organic polymer hybrid solar cells from the viewpoints of improvement of the synthetic methods of Cd-based compound nanocrystals, modification of the interfacial contact of Cd-based compound nanocrystals and organic polymer, optimization of the solvent, and the proportions of nanocrystals and organic polymer. Finally, we suggest some strategies to increase solar cell performance and suggest the future research direction of Cd-based compound nanocrystal organic-inorganic hybrid solar cells.

Key words: Hybrid solar cell, Cd-based compound nanocrystal, Nanocrystal synthesis, Interfacial contact
