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

Efficient hybrid plasmonic polymer solar cells with Ag nanoparticle decorated TiO2 nanorods embedded in the active layer.
TLDR
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
TLDR
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
TLDR
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.

TLDR
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.
