New Techniques to Harness Energy of Sun Research Paper

New Techniques to Harness Energy of Sun - Research Paper ExampleThe problem is the instability of oxide. The problem was overcome by using atomic layered deposition (ALD) proficiency that involves covering semiconductor with a thin film of atoms as zinc oxide and titanium oxide. Cuprous oxide is inexpensive and widely available, this ALD technique gives complete impermeable layer. The process advances photo-electrochemical production of HydrogenDr.Grimes (2005) writes at Penn state, Research work is underway to harness solar energy through highly uniform arrays of titania nanotubes arrays that would produce hydrogen and ultimately lead to rising in solar efficiency. Its about exposing water with these arrays to sunlight, through the process of photolysis and UV sheen efficiency would be high almost 13% and result in more hydrogen against per photon. The purpose is to replace most used and depleting energy sources as petroleum through creating a replenish-able stock of alternative energy.At the University of Utah (2007) physicists worked to convert heat into sound and then sound into electricity through formulating reinvigorated devices. First, they developed new heat engines formerly called thermoacoustics prime movers and then transformed sound into power using piezoelectric (piezo for pressure). How does it work? These devices are addressed in resonators (cylinder shaped), that contains a pile of material and kept in between hot and cold heat exchanger. After heat is applied, it builds to the threshold with air producing sound at a single frequency, these waves squeeze the device and electrical voltage is produced. These devices require the flexibility of moving parts but they have a long life. timberland Angela(2008) studied that Photovoltaic or solar panels are most known these days due to the least operational cost. It uses silicon or any some other similar material for chemical reaction with light results in a flow of currents that can be used or sto red in the battery.
