Organic-Inorganic Nanocomposites by Placing Conjugated Polymers in Intimate Contact with Quantum Rods

摘要

Recent advances in the synthesis and assembly of nanocrystals (NCs) provide unique opportunities to exploit NCs for the development of next generation organic/inorganic hybrid solar cells as one of the most promising alternatives to Si solar cells to deliver efficient energy conversion with inexpensive fabrication. These conjugated polymer- based photovoltaic devices capitalize on the advantages peculiar to conjugated polymers (CPs), such as light weight, flexibility, processability, roll-to-roll production, low cost, and large area, in conjunction with the high electron mobility and tunable optical properties of inorganic NCs. In the organic/inorganic hybrids, poly(3- hexylthiopene) (P3HT) is one of the most extensively utilized CPs due to its excellent solution processability, environmental stability, high charge carrier mobility, and tailorable electrochemical properties; and CdSe quantum dots (QDs) are most commonly investigated NCs because of their quantum-confined nature and well-matched energy level with P3HT.
