Journal ArticleDOI
Hybrid solar cells using PbS nanoparticles
Serap Günes,Serap Günes,Karolina P. Fritz,Helmut Neugebauer,Niyazi Serdar Sariciftci,Sandeep Kumar,Gregory D. Scholes +6 more
TL;DR: In this article, solution-processed bilayer heterojunction hybrid solar cells have been fabricated using size-quantized PbS nanoparticles and poly (3-hexylthiophene) (P3HT).
Journal ArticleDOI
Cylindrical Block Co-Micelles with Spatially Selective Functionalization by Nanoparticles
TL;DR: Electrostatic interactions can be used to selectively functionalize the new nanomaterials with Au and PbS NPs in a spatially selective manner to afford novel composite structures.
Journal ArticleDOI
Highly luminescent lead sulfide nanocrystals in organic solvents and water through ligand exchange with poly(acrylic acid).
Wanjuan Lin,Karolina P. Fritz,Gerald Guerin,Ghasem Rezanejade Bardajee,Sean Hinds,Vlad Sukhovatkin,Edward H. Sargent,Gregory D. Scholes,Mitchell A. Winnik +8 more
TL;DR: While there was a decrease in quantum yield associated with ligand exchange and transfer to polar solvents, as is commonly found for colloidal quantum dots, the quantum yields determined were impressively high and decreased over time as the solutions were allowed to age in the presence of air.
Journal ArticleDOI
Evolutionary shape control during colloidal quantum-dot growth.
TL;DR: This work proposes a means to achieve a further generation of shape design in nanometer-sized colloids by using a series of growth steps, each one building from the previous conditions of shape as well as surface-specific reactivity.
Journal ArticleDOI
IV–VI Nanocrystal–polymer solar cells
Karolina P. Fritz,Serap Guenes,Joseph M. Luther,Sandeep Kumar,N. Serdar Sariciftci,Gregory D. Scholes +5 more
TL;DR: In this paper, the removal of the surface ligand, by pre-rinsing the nanocrystals and subsequent annealing, generates a smoother film with a greater degree of cross-linking between the NCs.
