Essays on Solar Energy

For Solar Energy Multi-Coatings (SEMCS) applications we investigated the influence of surface roughness with the number of layer on the optical and structural properties, hence, improved transmittance, reduced reflectance, and increased band gaps for single-, double-, and triple- coatings of semiconductors, more over the decrease…

Solar farms require a large space for their implementation and operation. If a single domestic solar panel is already a hulk, the panels used in solar farms are much larger. Its landscape impact, therefore, is also. But, is this characteristic always an inconvenience? This peculiar…

The development of solar cell technology began on 1839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop when light fell upon the electrode. The major events…

The solar cell created is actually a hybrid, comprised of tiny nanorods dispersed in an organic polymer or plastic. A layer only 200 nanometers thick is sandwiched between electrodes and can produce at present about .7 volts. The electrode layers and nanorods /polymer layers could…

Solar Energy is energy from the sun or known as radiant energy emitted by the sun. How is it produced? Solar power is arguably the cleanest, most reliable form of renewable energy available, and it can be used in several forms to help power your…

We hear a lot about clean energy, biofuels, also about the price of oil, the increases in the receipt of light. But do we really know where the energy comes from and if it is more or less polluting? To begin with, we can talk…

The working concept of all PV cells is virtually based on ‘photovoltaic effect’. In common, photovoltaic effect implies generation of voltage difference at the junction of 2 dissimilar materials in reply to ultraviolet/visible/near infrared or other type of radiation. Hence, a cell is a 2…

A residential PV power system enables a homeowner to generate some or all their daily electrical energy demand on their own roof. PV systems can also include battery backup capability to operate selected circuits in the residence for hours or days during a utility outage….

SOLAR ENERGY Introduction: In 1839 Alexandre Edmond Becquerel found the photovoltaic impact which clarifies how power can be produced from sunlight. He asserted that “sparkling light on an anode submerged in a conductive arrangement would make an electric current.” Sun based vitality is the acquired…

Thermal energy can be solar, coal-based, hydrothermal, wind-generated or geothermal. Solar thermal power options are part of the low-cost PVs which can delivers power through solar energies and this is widely popular in China where recent development in Gansu and Qinghai Province aim to trap…
