Amorphous silicon

electricity-generation increased when exposed to light. During the 19th and 20th centuries, global researchers experimented with selenium solar cells and cadmium sulfide (CdS), but a silicon PV cell that could convert sunlight into enough power to run electrical equipment was only…

BACKGROUND OF THE COMPANY Sanyo began its operations as Sanyo Electric Works in 1947 in Moriguchi, Osaka. Earlier it manufactured bicycle generator lamps. Later in the year 1950 it changed its name to Sanyo Electric Co. Ltd. From the very beginning they were quality conscious. Sanyo was the first company to launch plastic radios in Japan and then the company started manufacturing televisions. Later they get listed on the Tokyo and Osaka stock exchanges. In 1969 it established two subsidiaries…

• SunE Sky 13th Sideroad, LP (“SunE Sky” or the “Borrower”), a bankruptcy-remote limited partnership between SunEdison, LLC (“SunEdison”) (NR) and SkyPower Limited (“SkyPower”) (NR) (the “Sponsors”), owns and operates the 13th Side Road Solar Energy Project (the “Project”) - an 8.0 MWac PV solar project that was constructed pursuant to Ontario’s Renewable Energy Standard Offer Program (“RESOP”) and sells the energy output to the Independent Electricity System Operator (the “IESO”) (Aa2; SFS 2)…

Since the industrial revolution, people’s life quality has improved dramatically, along with new machines invented and new technology innovated. While people are enjoying their life with those advancements, energy consumption has also increased enormously. With limited resources on earth, the development of renewable technology has become the focus for the past decades. The sun, the giant burning star that is 92 million miles away from us, is warming us the earth and providing us with light and…

Prefilled syringes are a fast growing alternatives to vials for many drug products. Increased interest in prefilled syringes is largely driven by the advantages they offer relative to the vials. Currently, most prefilled syringes are made of glass, but plastic syringes are gaining popularity, particularly in applications for which glass is an unsuitable delivery system. Plastic has been an alternative to glass in prefilled syringes since the early 1990’s. Earliest plastics were, however, made of…

The word “photovoltaic” combines two terms – “photo” means light and “voltaic” means voltage. A photovoltaic system in this discussion uses photovoltaic cells to directly convert sunlight into electricity. A photovoltaic (PV), or solar electric system, is made up of several photovoltaic solar cells. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, they are connected together to form larger units called modules.…

Some trace elements are known to reside in mineral/fluid inclusions rather than in the silica host. However, silicified woods are mainly permineralized with silica polymorphs and thus, retain the fundamental structure of a silicon tetrahedron, especially quartz (normally composed of nearly 100% SiO2). In addition, other oxides (e.g. Al2O3, Na2O, TiO2) present in small amount are generally due to either small inclusions of other minerals (e.g. rutile) or liquid infillings in…

Orbiting spacecraft need a safe, efficient, and cost-effective way of penetrating planetary atmospheres and landing without compromising the cargo or– more importantly– the passengers. In the case of planet Earth, orbiting vehicles generate a substantial amount of thermal energy upon re-entry into the atmosphere, and the management of that immense amount of heat is fundamental in providing a safe environment for the crew and instrumentation on board the vehicle. The design of an efficient and…

Chalcopyrite is a copper iron sulfide mineral. Its coloring is metallic brassy to a brown-orange, and on the Mohs scale, it has a hardness of 3.5 to 4. The chemical formula of chalcopyrite is CuFeS2. It is the most commonly occurring copper containing mineral in New Zealand, but it is only created near volcanic areas. On the metaphysical level, chalcopyrite is used for meditation, specifically for opening the third eye chakra (crown chakra), and physical healing. The stone clears any energy…

CHAPTER I INTRODUCTION 1.1 BACKGROUND STUDY Wastewater in the textile , plastic, paper and cosmetics industry is a major threat to the environment. The volume of wastewater produced starts from different processes throughout from the pretreatments to the final treatment. The contents found in the wastewater are complex, having inorganic and organic compound chemicals in it and aquatic lives are at risk. Some of these wastes have even caused mutation in genetic coding of the marine…
