This paper introduces the fundamental physical characteristics of organic photovoltaic (OPV) devices. Photoelectric conversion efficiency is crucial to the evaluation of quality in OPV devices, and enhancing efficiency has been spurring on researchers to seek alternatives to this problem. In this paper, we focus on organic photovoltaic (OPV) devices and review several approaches to enhance the ...

In the present work, a computational study is carried out investigating the relationship between the biosensing and the electrical characteristics of two-terminal Schottkybarrier silicon nanowire devices. The model suggested successfully reproduces computationally the experimentally obtained electrical behavior of the devices prior to and after the surface bio-modification. Throughout modeling ...

The development of strategies for addressing arrays of nanoscale devices is central to the implementation of integrated nanosystems such as biological sensor arrays and nanocomputers. We report a general approach for addressing based on molecular-level modification of crossed semiconductor nanowire field-effect transistor (cNW-FET) arrays, where selective chemical modification of cross points i...

Accurate measurement of water levels deeper than 1,000 feet in wells requires specialized equipment. Corrections for stretch and thermal expansion of measuring tapes must be considered, and other measuring devices must be calibrated periodically. Borehole deviation corrections also must be made. Devices for recording fluctuation of fluid level usually require mechanical modification for use at ...

Cloud Computing is becoming more and more popular, and various cloud services have appeared to make our lives easier. Mobile devices can also benefit from Cloud services: the huge data users produce with these devices are continuously posted to online services, which may require the modification of these data. Using cloud storage services together with computation-intensive infrastructure servi...

The educational experience of students in a Computer Engineering capstone design course can be greatly enhanced by providing a framework that enables students to design devices that are accessible over the web. The framework consists of inexpensive hardware and software that permits the connection of arbitrary devices to a web page. Remote users can then interact with the physical device throug...

In an organic-based solar cell, the short exciton diffusion length of organic materials requires effective donor-acceptor heterojunction at the nanoscale. In this work, hybrid inorganic/polymer solar cells based on ZnO nanostructures and poly(3-hexylthiophene) (P3HT) are constructed to study the effects of ZnO morphologies and wettability of the surface on the P3HT infiltration ability and char...

New alcohol-soluble conjugated small molecule electrolytes (CSMEs), 3,6-bis-(5-benzoic acid-thiophen-2-yl)-2,5-bis-(2-ethylhexyl)-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione liquid crystalline (DPP-COOH) and di-tetrabutylammonium cis-bis(isothiocyanato)bis(2,2'-bipyridyl-4,4'-dicarboxylato)ruthenium(II) dye (N719), are developed as interfacial modification in inverted polymer solar cells (PSCs)...
