Computational simulation of the molecular structure and properties of nanomaterials potentially useful for the fabrication of solar cells and photovoltaic devices
Most of the solar cells used in the terrestrial applications are bulk-type single- or multi crystalline silicon solar cells. However, a drastic reduction of cell cost and increase of the conversion efficiency cannot be expected by using the conventional materials and solar cell structures. Moreover, a shortage of the feedstock of high-purity silicon is predicted in the near future because of the requirements of the microelectronics industry. Therefore, research and development of solar cells with low production cost, high conversion efficiency and low feedstock consumption are required.
An important concept to reach this goal is to use nanostructured materials instead of bulk materials. The motivations to employ nanostructures in solar cells are largely divided into three categories as follows: 1. To improve the performance of conventional solar cells. 2. To obtain relatively high conversion efficiency from low grade (inexpensive) materials with low production cost and low-energy consumption. 1. To obtain a conversion efficiency higher than the theoretical limit of conventional p –n junction solar cell.

Zinc oxide (ZnO) has a large application potential owing to the diverse physical properties and the fine-tuning in the preparation process. The wide band gap of 3.2 eV has also made it suitable for short-wavelength optoelectronic devices, including UV detectors, photocatalysts, laser diodes and light-emitting diodes (LEDs).
The 21st century is seeing a big revolution in the way information is displayed electronically. Organic electroluminescent displays based on OLEDs on rigid or flexible substrates are envisioned to play a significant if not major role in the area of flat panel displays.
Computational Chemistry of the Molecular Structure and Properties of Electroluminescent Conjugated Polymers
Lithium-ion batteries are one of the great successes of modern materials electrochemistry. Their science and technology have been extensively reported.
However, for new generations of rechargeable lithium batteries, not only for applications in consumer electronics but especially for clean energy storage and use in hybrid electric vehicles, further breakthroughs in materials are essential. One avenue that is already opening up is that of nanomaterials for lithium-ion polymers batteries.
It is generally believed that PEMFCs (Polymer Electrolyte Membrane Fuel Cells) will play an important role in energy supply in the near future. Fuel cells will be providing energy for cars and trucks, producing electricity for utilities, and heating and cooling homes and businesses.
PEMFCs use a proton exchange membrane as an electrolyte.
The proton-conducting membrane is the key component of a fuel cell system, because only extremely stable membranes can withstand the harsh chemical and physical environment, which includes active noble metal catalysts, temperatures, which can exceed 100 ◦C, aggressive fuels and their partial oxidation products, aggressive oxidants, and the formation of reactive radicals.
The high cost and environmental inadaptability of the fluorinated polymers used for PEM fuel cells, urge the necessity to develop alternative proton-conducting polymers. Theoretical studies of the systems can provide experimentalists with ideas about possible degradation routes and prove/correct existing assumptions for the performance reduction.
