Effect of ZnSe nanoparticles in the PEDOT: PSS photodiodes

Abstract
In this article we report the photovoltaic properties of devices made using a highly conducting polymer electrode, from poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) incorporated with ZnSe nanoparticles on ITO substrate as an anode and a Poly(3-hexylthiophene-2,5-diyl) (P3HT) mixed with Phenyl-C61-butyric acid methyl ester (PC61BM) in the ratio of 1:1 as the active layer. The device performance was compared with that of devices made with PEDOT-PSS without ZnSe nanoparticles on ITO substrates. The IV characteristics were studied and the surfaces of PEDOT:PSS with ZnSe were imaged using Transmission electron microscopy (TEM). It shows that the functions ...

Abstract

With the rise of the internet, books, and mobile devices, there has been the rise information availability. A lot of information available for individuals in an office is not beneficial because it will take time to process. There are a lot of problems that are seen with the availability of too much information to be processed. One issue is that it is hard to go through information and separate what needs to be processed from those that should not be processed. Information overload is a significant problem that is faced by many organizations today. This is because of the availability of ...

There are two broad categories of energy: renewable and non-renewable sources. In describing alternative sources of energy, we shall limit ourselves to renewable sources, that is, those that cannot be depleted. Examples of renewable sources of energy include solar energy, geothermal, biomass, wind, tidal and many others. The discussion will further be biased on solar energy in this case. The purpose of choosing this alternative is to find out the energy source that is not only environmental friendly but also clean and viable.
As far as originality is concerned, solar energy has been utilized by man for thousands ...

Photosynthesis/Semiconductor-based solar cell

Photosynthesis is a process where plants manufacture carbohydrates from water, carbon dioxide and minerals with the use of light as an energy source. Plants degenerate water and carbon dioxide into carbon, hydrogen and oxygen which form glucose, the source of energy for plants that helps in food production and growth. A semiconductor-based solar panel is used to harness solar energy into electricity form. People can use this device to harvest sunlight energy and use it as electricity.

Solar cells and plant cells use sunlight and change it into energy. The process by which sunlight is converted into energy differs though. ...

Generation of electrical power through solar technology involves the conversion of energy in the sun’s radiation into electricity. The sun emits electromagnetic radiation which contains energy in the form of photons. Solar panels harvest this energy and convert it to electricity though a phenomenon referred to as the photovoltaic effect. A solar panel is made up interconnected solar cells, which are in turn fabricated from millions of light sensitive p-n junction diodes. The diodes are made from doped semiconductor materials such as crystalline silicon. Doping silicon with an impurity such as phosphorous introduces charge carries referred to as ...

Abstract

The use of thermistors started when the scientists discovered that metals have a semiconductor property. The inventor of the first operating thermistor is Samuel Ruben. Thermistors are resistors which could vary their resistance with the change of temperature. The industry of thermistor rapidly increases due to its reliability and low price. Then, its uses became wider as more and more devices are installed by the thermistors. As the technology progresses, the use of thermistors in any devices and instruments also developed (Ametherm, np).

History

In 1833, Michael Faraday discovered that silver sulfide (Ag2S) has a semiconductor property. He observed it using the ...

Abstract

The discovery of semiconductor property of a metal began the development of thermistors (Lavenuta, np). Samuel Ruben invented the first practical thermistor (Electrotechnik, np), and since then, the demands of such technology increased because it is considered cheap and reliable. Today, there are many industries, devices and instruments that use thermistors. (Ametherm, np).

History

The semiconductor property of silver sulfide (Ag2S) was the first ever recorded NTC (Negative Temperature Coefficient) thermistor and was observed by Michael Faraday in 1833. However, because of the difficulty to produce thermistors, and its applications were less understood, the manufacturing of thermistors came only during the ...

Introduction

Strain is the relative change in length of material when subjected to stress; bonded wire strain gauge is a device that is used to measure the strain. The device measures strain in terms of resistance which is affected by a metallic foil design within the device. Whenever the foil is distorted, electrical resistance changes. This resistance is related to strain directly. This paper will discuss bonded wire strain gauge with regards to its discovery, evolution and applications.

Operation of a strain gauge

When an object is subjected to a stretching force it stretches. When a strain gauge is attached to that object, the foil stretches too. The effect ...
