or rely on nutrients derived from other living organisms. A semiconductor-based solar cell is devised to convert light to electric current. The solar cell directly converts the energy in light into electrical energy through the process of photovoltaics (a field of semiconductor technology involving the direct conversion of electromagnetic radiation as sunlight‚ into electricity). Solar cells do not use chemical reactions to produce electric power‚ and they have no moving parts. Most solar cells

has the disadvantages of using it. One of the advantages of using solar power in building design is that it can help in saving energy. According to Russel (2009)‚ solar energy provides electricity generation by direct use of it heat or photovoltaic mechanism (Solar Cell). The solar energy can be used for many things‚ such as heating our home‚ making hot water and even for cooking dishes. Furthermore‚ this solar power will always available every day anywhere the sun shines. The solar cell

ABSTRACT: HELIOS project was a part of NASA’s ERAST programme (Environmental Research Aircraft and Sensor Technology). It was developed by NASA and Californian company AeroVironment Inc. ERAST programme develops pilotless solar powered airplane technology. The HELIOS construction is based upon its predecessors like NASA’s solar plane Pathfinder‚ which was successfully tested a few years prior to HELIOS. Due to its speed HELIOS was able to fly over the same spot for days or weeks‚ therefore‚ in

In 1839‚ Alexandre Edmond Becquered discovered a photovoltaic effect which is the process of electricity generated from the sunlight. Over a hundred years later another major breakthrough comes from Calvin Fuller‚ Gerald Pearson and Daryl Chapin discovered the

and horns on many offshore gas and oilrigs‚ lighthouses‚ railroad crossings. Domestic solar applications were viewed‚ as practical applications in remote locations where grid connected utilities could not exist affordably. (How solar works) Photovoltaic cells absorb energy from sunlight. Once the light hits the panels it heats them and turns it into a direct electrical current. This electricity is fed through an inverter to become alternating current (AC)‚ the same form of electricity that is

In the other hand‚ Active solar systems use electrical and mechanical components such as photovoltaic panels‚ pumps‚ and fans to process sunlight into useable outputs. Using solar energy has a lot of advantages for humanity; some of those

from the sun‚ then water is pumped through these pipes. These panels are positioned in such a way to maximize the absorption of heat throughout the day and can help in reducing the electricity bills. Another approach to harness solar energy is photovoltaic Cells. This method converts the sun’s energy into electricity. These cells are silicon based pieces of materials that absorb the sun’s light. When the sunlight enters the cells‚ it causes the electrons to move. These electrons move in a certain

In terms of market‚ we know also that many governments have long-term objectives that will probably keep alive public and private investments in renewable energy power sources‚ where photovoltaic segments have a solid ground. 2.
