چکیده

This project is studying photovoltaic solid state devices utilizing semiconducting colloidal nanocrystal quantum dots. Objectives include enabling fabrication of hybridquantum dot (QD) planar heterojunction PVs, improving morphology of printed QD films, and scale-up of QD synthesis. Quality, Productivity and Accomplishments (Average Rating 3.2) Rating Comments 3.0 Well-qualified team led by Bulovic and Bawendi. Good facilities and capabilities for exploring QD based solar cells. 4.0 The QD expertise level is very high, and the high Voc is an important achievement, as well as the deposition of highly uniform QD layers. 3.0 The research team at MIT is very strong. The collaboration between chemistry and electrical engineering makes good sense. The resources available at MIT are more than adequate for the proposed research. Productivity includes printed quantum dot layers and subsequent processing of additional layers to generate solar cells has been realized. The processing is scalable. 3.0 Quality of research is high, team is well positioned to resolve or determine potential barriers. Main focus is on manufacturability but some main aspects of QD solar cells have not yet been addressed. 3.0 Research group is a combination of electrical engineering and chemistry at MIT. The investigators have made significant progress experimentally but there have been limited publications resulting from the work so far.

Optical gain and stimulated emission in nanocrystal quantum dots.

The development of optical gain in chemically synthesized semiconductor nanoparticles (nanocrystal quantum dots) has been intensely studied as the first step toward nanocrystal quantum dot lasers. We examined the competing dynamical processes involved in optical amplification and lasing in nanocrystal quantum dots and found that, despite a highly efficient intrinsic nonradiative Auger recombina...

Quantum gate based on Stark tunable nanocrystal interactions with ultrahigh-Q /V field modes in fused silica microcavities

We investigate the use of nanocrystal quantum dots as a quantum bus element for preparing various quantum resources for use in photonic quantum technologies. Using the Stark-tuning property of nanocrystal quantum dots as well as the biexciton transition, we demonstrate a photonic controlled-NOT CNOT interaction between two logical photonic qubits comprising two cavity field modes each. We find ...

In vivo imaging of quantum dots encapsulated in phospholipid micelles.

Fluorescent semiconductor nanocrystals (quantum dots) have the potential to revolutionize biological imaging, but their use has been limited by difficulties in obtaining nanocrystals that are biocompatible. To address this problem, we encapsulated individual nanocrystals in phospholipid block-copolymer micelles and demonstrated both in vitro and in vivo imaging. When conjugated to DNA, the nano...

P-155: Studies of Cytotoxic Effects ofCdSe Quantum Dots on Fetal Development Testis and Epididymis in Albino Mice

Background: Quantum dots (QDs) are among the most promising items in the nanomedicine toolbox. These nanocrystal fluorophores have several potential medical applications including nanodiagnostics, imaging, targeted drug delivery, Nevertheless, in vivo cytotoxicity of these nanoparticles has not been highly considered. For this reason, the cytotoxic effects of CdSe QDs on testis and epididymis e...
