Journal ArticleDOI
Covalent Coupling of Quantum Dots to Multiwalled Carbon Nanotubes for Electronic Device Applications
TL;DR: In this paper, a controlled synthesis of multiwalled carbon nanotube−quantum dot (CNT-QD) heterojunctions using the ethylene carbodiimide coupling procedure (EDC) was reported.
Journal ArticleDOI
Hierarchical placement and associated optoelectronic impact of carbon nanotubes in polymer-fullerene solar cells.
TL;DR: It is demonstrated that controlled placement of a single-walled CNT (SWNT) monolayer network at four different positions in polymer-fullerene bulk-heterojunction (BHJ) solar cells leads to major electro-optical changes in the device functionality, including an increased fluorescence lifetime of poly-3-hexylthiophene (P3HT).
Journal ArticleDOI
Trilayer hybrid polymer-quantum dot light-emitting diodes
TL;DR: In this article, a trilayer hybrid polymer-quantum-dot light-emitting diode was fabricated by sandwiching a CdSe-ZnS core-shell quantum-dot (QD) layer, a few monolayers thick, between films of polyvinylcarbazole (PVK) and an oxadiazole derivative (butyl-PBD).
Journal ArticleDOI
A New Architecture for Transparent Electrodes: Relieving the Trade-Off Between Electrical Conductivity and Optical Transmittance
Ping Kuang,Joong Mok Park,Wai Leung,Rakesh C. Mahadevapuram,Kanwar S. Nalwa,Tae Geun Kim,Sumit Chaudhary,Kai-Ming Ho,Kristen P. Constant +8 more
TL;DR: A new architecture for transparent electrodes is reported, which leads to quasi-elimination of this tradeoff between optical transmittance and electrical conductivity, and the experimental results show that the novel structure is very promising for such applications.
Journal ArticleDOI
On realizing higher efficiency polymer solar cells using a textured substrate platform.
TL;DR: It is imperative to develop fabrication methodologies that can enable effi cient optical absorption in fi lms thinner than optical absorption length and the most desirable methodology would be one which can also substantially improve absorption at the band edge of conjugated polymers.
