How the Angle of a Solar Cell Effects the Voltage Produced

In Part 1 of the lab, a solar cell was created and tested for its capability to conduct electricity. After researching the processes that contribute to the conductive property, it was found that the oxidized substance is the dye, as it donates an excited electron to the titanium oxide. Consequently, titanium oxide is reduced before it donates an electron to the cathode. The electrolyte solution was found to replenish the dye with electrons so it could continue to act as a reducing agent. Certain

this is the depletion of Earth’s natural resources and its harm to the environment. Clean Energy is how we can fix such things. For the generations beyond, the people of earth need to focus on the technology to make a clean energy future a reality. If there is no change, the future, will surely and quickly turn to peril. So now, entering the stage, is the solar cell. Solar cells or Photovoltaic cells capture the energy from the sun and convert it to electrical energy (Singh and Ravindra 2012). They

renewable energy in the energy sector in order to make Vision 2030 a reality. Renewable energy is the energy that comes from sources that are continually replenished. This include: solar energy, wind energy, hydropower, ocean energy, geothermal energy. One of the promising renewable sources of energy is solar energy. Solar renewable energy has many advantages and these include: Plenty of resource: The sunlight reaching the Earth’s surface is abundant approximately 8000 (120000 TW/Hr) times

electric current in a wire. These atoms are the smallest particle into which an element can be divided without losing its property. A single atom consists of three basic components: a Proton, a Neutron and an Electron. An atom is similar to a small solar system, so is the nucleus in the centre of an atom. Protons and neutrons are contained within the nucleus. Electrons orbit around the nucleus which could be similar to planets orbiting around the sun. As an electrician I will also be

A solar cell is a device which produces electricity through the conversion of light energy, through the photovoltaic effect. The photovoltaic effect is a chemical and physical phenomenon, and relates to the creation of electrical current within a material when it is exposed to light. Solar cells are considered to be photovoltaic, despite whether the source of light is produced artificially, or is from the sun. History of a Solar Cell It was in 1839 when the photovoltaic effect was first discovered

hydraulic and solar are archaic due to fact that they have been used centuries ago. They need to focus on current renewable energy trend like petroleum has led to the abandoning of wind, hydraulic, and solar source. Due to the huge amount of fuel consumption fuel prices and environmental problems like global warming so that we need to returning back to renewable energy sources. Renewable energies are infinite, clean and we can use them at same place where they are produced. Solar cell Converting the

would not exist without the heat and light provided by the Sun. Harnessing the energy from the sun for hot water and electrical power could provide a renewable, low carbon energy source, and presents an attractive way of mitigating climate change. PV cell photovoltaic is the direct conversion of light into electricity. It uses materials which absorb photons of lights and release electrons charges. 1.1 Photovoltaic systems A Photovoltaic system is an arrangement of components designed to supply usable

RENEWABLE ENERGY RESOURCES - WIND TURBINES VS SOLAR PANELS – HOW THEY WORK Wind turbines: A wind turbine turns wind into energy. As wind blows towards the blades of the turbine, the rotors spin around, capturing kinetic energy from the wind. The rotor blades are able to rotate around the hub (located at the front, middle of the turbine) allowing them to meet the wind at the best possible angle. Inside the nacelle (the main body of the turbine), the gearbox is able to convert the low-speed turning

The continued reliance on fossil fuels over the centuries has led to these resources being almost completely exhausted. Furthermore, their use has had extremely negative effects on the environment, namely pollution and global warming as a result of the build-up of greenhouse gases. It is therefore essential to consider alternative, cleaner energy sources. It was decided that six renewable energy sources should be researched in order to determine which are most suitable for use in the West of Scotland
