Carbon nanotubes in photovoltaics Essays

The nanotechnology potentially makes the human to rendering to recent and increasing hazards due to some individual properties such as its very small size and high ratio of area to mass. Nanotechnology is the competent invention of materials and systems in nanometer length scale, and exploits the rising properties and phenomenon which have been developed in nano scale. The word “nano” means 10-9, so a nanometer is one-billionth of a meter. One description of nanoscience is the study of atoms, molecules

diameter. The ratio of a size of an ordinary soccer ball to the planet Earth is the same as the ratio size of a Buckyball molecule to a soccer ball. Chemical structure and properties Buckyballs are composed of carbon atoms linked to three other carbon atoms by covalent bonds. However, the carbon atoms are connected in the same pattern of hexagons and pentagons you find on a soccer ball, giving a buckyball the spherical structure as shown in the following

INTRODUCTION 1. INTRODUCTION 1.1 Fundamentals of capacitor Capacitor is very useful component in the field of engineering and it is used in various electrical and electronic circuitries. Capacitor stores energy in the form of electric field. Capacitor also known as condensers which stores energy when charge and release energy when discharge . There are different forms of capacitors which are used widely, but common thing about this all capacitors is that they are made of two conductors
