need for a more sustainable form of energy. Solar energy is one of them and is becoming more and more important and will hopefully soon replace this obsolete technology. There exist several technologies for solar cells; a dye-sensitized solar cell is one of them. In 1972 the first dye-sensitized solar cell was demonstrated, it appeared that illuminated organic dyes could generate electricity at oxide electrodes. At that time the dye-sensitized solar cell were unstable and their efficiency was low
water) to chemical energy and storing it in the bond of sugar (fruits). The process of the photosynthesis takes place in the chloroplasts, specifically using chlorophyll (the green pigment. Human are familiar with the utilized the sun energy by using solar energy system ... ... middle of paper ... ...cial photosynthesis: There many welfares that can be brought by artificial photosynthesis not only to mankind but also to the world, (the problem of global warming). The product that artificial photosynthesis
Introduction Carbon exists in different forms such as graphite, amorphous carbon, and diamond, among others. Its graphitic carbon has a hexagonal and crystalline structure that easily cleaves which in turn makes it a soft material and effective lubricant. Its widely occurrence in earth’s crust makes it one the most abundant elements. Carbon presents itself in different allotropes such as Graphene, fullerenes and carbon nanotubes. Some of these allotropes have proven to be conducting and others to
effects of Green Nanotechnology in Solar. Although Solar Energy is a flexible source of where energy could be directly or indirectly converted into forms of energy, it’s still not perfect. With its inefficiency, scientists are trying to find alternative solution to store solar cells for as long as possible. The main process of capturing solar energy happens at the nanoscale. With solar cells, it gets more efficient the tinier it gets. The converting rate of solar energy is equally price competitive
My mother developed type 2 diabetes in her late 30’s, and I witnessed her injecting herself with insulin each morning to ensure that her body functions well throughout the day. That’s not something anyone would look forward to on any given day. Consequently, I would like to be part of a change to find a solution for that situation. It has always intrigued me how the same foods that are necessary for the nourishment of our bodies are the same foods that can cause some of the worst and most life-threatening
Specifically, three growth methods are reviewed in this survey: (1) sol-gel method (2) direct oxidation method (3) hydrothermal method. Three applications of TiO2 nanowires are touched in this survey: (1) photocatalytic (2) gas sensing (3) dye-sensitized solar cell. Introduction Titanium dioxide (TiO2) is often found in commercial products such as paint, sunscreen, toothpaste, and etc. [7]. Further research and advancement of TiO2 was initiated after the discovery of its photocatalytic property that
Solar energy in simple is the energy provided by the sun known as solar radiation. This energy can be used to produce solar electricity or heating. This energy can be for domestic use or even commercial use. The solar technologies are classified into 2 types, the solar photovoltaic (PV) and the concentrated solar power (CSP). For solar photovoltaic technology, the conversion of solar energy to electrical energy directly requires solar photovoltaic cells. In brief, the sunlight strikes the PV cell
2.7. Sol-Gel Method The sol–gel method allows the synthesis of TiO2 nanoparticles with different morphologies like sheets, tubes, particles, wires, rods, mesoporous and aerogels. The sol–gel method is also used due to the easy technique, low price, the purity of oxides obtained and the lower synthesis temperatures. The raw materials and methodologies differ according to the type of nanoparticles required finally. 97 % % titanium tetra iso propoxide (TTIP) has been utilized by several studies as
