We demonstrate that semiconductor nanorods can be used to fabricate readily processed and efficient hybrid solar cells together with polymers. By controlling nanorod length, we can change the distance on which electrons are transported directly through the thin film device. Tuning the band gap by altering the nanorod radius enabled us to optimize the overlap between the absorption spectrum of the cell and the solar emission spectrum. A photovoltaic device consisting of 7-nanometer by 60… 
Hybrid solar cells with vertically aligned CdTe nanorods and a conjugated polymer
Vertically aligned CdTe nanorods were fabricated by electrodeposition and were applied for the active layer of solar cells after being combined with poly(3-octylthiophene) (P3OT), a conjugated

Efficient hybrid plasmonic polymer solar cells with Ag nanoparticle decorated TiO2 nanorods embedded in the active layer.
It is demonstrated that when Ag nanoparticle decorated TiO2 nanorods were introduced into the active layer of polymer-fullerene based bulk heterojunction solar cells, the photocurrent significantly increased and the energy conversion efficiency was dramatically enhanced to 4.87% from 2.57%.


Integrated optoelectronic devices based on conjugated polymers
An all-polymer semiconductor integrated device is demonstrated with a high-mobility conjugated polymer field-effect transistor driving a polymer light-emitting diode (LED) of similar size, which represents a step toward all- polymer optoelectronic integrated circuits such as active-matrix polymer LED displays.

Shape control of CdSe nanocrystals
Control of the growth kinetics of the II–VI semiconductor cadmium selenide can be used to vary the shapes of the resulting particles from a nearly spherical morphology to a rod-like one, with aspect ratios as large as ten to one.
Charge separation and transport in conjugated-polymer/semiconductor-nanocrystal composites studied by photoluminescence quenching and photoconductivity.
A simple model is described to explain the recombination in these devices, and how the absorption, charge separation, and transport properties of the composites can be controlled by changing the size, material, and surface ligands of the nanocrystals.
We study photoinduced electron transfer from derivatives of poly(p-phenylenevinylene) (PPV) and nanocrystals of cadmium selenide via photoluminescence (PL) quenching and photoinduced absorption (PIA)

This paper proves that Cd(CH3)2 can be replaced by CdO and develops a one-pot synthesis which does not require separated preparation of cadmium complex and is reproducible and simple and thus can be readily scaled up for industrial production.
Semiconductor Clusters, Nanocrystals, and Quantum Dots
Current research into semiconductor clusters is focused on the properties of quantum dots-fragments of semiconductor consisting of hundreds to many thousands of atoms-with the bulk bonding geometry
