Solar Energy Applications
Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.
There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.
Photovoltaics System
Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.
Solar Cell Module
Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.
Thin Film Solar Cell
Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

Transparent Solar Cells from MIT
Glass window as a source of electrical energy can now be realized with ease. Many methods can be done, one of which is transparent solar cells that are used as a coating of glass.
For a team of scientists at the Massachusetts Institute of Technology, the utilization of solar cells as a coating of glass windows is not enough. The team consisted of Vladimir Bulovi? and Richard Lunt, managed to make organic solar cells are integrated into the glass with a coating on the inside of two sheets of glass, with modern technology, the two sheets of glass are combined into a glass. In this way, a layer of solar cells are protected from outside weather and friction that will cause damage.

Flexible Solar Cell by Spheral Solar Power
Car bonnets, roof tiles and building facades can quickly enter the colorful and flexible solar panels to complement their conventional resources. Spheral Solar Power has produced efficient and flexible solar cells, which produces electricity at a lower cost and open an array of new applications for renewable energy.
Like denim material consists of thousands of tiny silicon beads attached to aluminum foil – each bead acting as an individual solar cells and uneven surfaces offer a larger area for light collection. Production costs can be reduced through the use of recycled silicon and this, combined with the efficiency comparable to standards photovoltaic cells and the versatility of a flexible material make Spheral solar cells potential to dramatically expand the use of renewable energy.
Building design can take advantage of hundreds of colors, styles and shapes to smoothly integrate solar cells. Spheral cells can be used to reflect light from or transmit light into the building and expand their flexibility for use in the company logo.
In tile the cells can be incorporated into the curved substrate opening various markets applications and automobile manufacturer may have found an alternative aerodynamic to rigid photovoltaic cells that are not practical in terms of vehicle design.
Commercial production of flexible cells are expected to begin in late 2003.

The history of “Photovoltaic”
The history of “Photovoltaic” (PV) industrial development has been running about 50 years, and have been many studies done in the hope that one day could produce cheap solar cells and feasible compared with artificial electricity (hydro or nuclear) to solve the problem of availability of environment friendly electricity at all levels of this world.
In the late 19th century, solar electricity discovered by German physicist named Alexandre Edmond Becquerel accident where the sun rays fall on the solution of electro-chemical research materials, so the charge of electrons in the solution increases, there is no scientific explanation of the event. Not until the early 20th century, Albert Einstein called the discovery of this natural electrical event with “Photoelectric Effect”, which is the basic understanding of the “Photovoltaic Effect” (Albert Einstein got the Nobel Prize in Physics). 
“Photoelectric Effect” comes from Einstein’s observations on a plate of metal release “photon” particles of light energy when exposed to sunlight. Photon continuously urged metal atoms and form a particle “Photon Energy”-is the wave of light energy.
Ultraviolet light waves, light that are high charged photon energy and short wavelength, while red light (infra-red) is low charged photon energy and long waves.
Then around the year 1930, research continued and related to discovery of the “Quantum Mechanics” concept, to create new technologies “solid-state”, which then the Bell Telephone Research Laboratories company create the first solid Solar Cell.
Year 1950 – 1960, technology of solar cell design and efficiency continued and applied to the spacecraft (photovoltaic energies). In 1970′s, the world encourage “renewable” alternative energy sources and environmentally friendly, then the PV is applied to the “low power warning systems” and “offshore buoys” (but the PV production could not be much because it is still “handmade”).
Just in 1980, the PV companies joined with government energy agencies in order to produce the PV cells in large numbers, so the price of solar cells can be more suppressed as low as possible.
