solar photoelectric energy is converting sunlight to solar energy via photovoltaic cells.

Solar panels convert sunlight into electricity that can be used by households and businesses. This feat is possible due to the photoelectric effect, a physical principle that converts the energy from sunlight to electricity. The effective photoelectric benefits are not limited to solar panels. There are also various other equipments based on effective photoelectric.

At we know, the photovoltaic effect describes how photons striking a metallic surface cause electrons in that metallic material to be knocked loose. In systems such as solar panels, the electrons can be captured as electricity. In situations where the electrons are not collected, such as in a spacecraft being struck by light, the object will have a net positive static charge, and systems have to be designed so that the static charge will not damage electronic equipment.

In order for one electron to be released, the energy of the striking photon must be greater than work function of the electron. An electron must fully absorb the energy of one proton with high enough energy to be released from the metallic material.

It was said that the results of the photoelectric effects were observed as early as 1839 by Alexandre Edmond Becquerel, but the existence of electrons was not realized until 1899 when their existence was deduced by J. J. Thomson. Nikola Tesla refined the description of the photoelectric effect, but it was Albert Einstein who in his 1905 paper "On a Heuristic Viewpoint Concerning the Production and Transformation of Light", created the modern definition. It was this work that won Einstein the Nobel Prize in 1921. The major advancement put forth by Einstein was that the energy of the dislodged electrons was dependant on the frequency of the lightwaves that strike the object, rather than the intensity of the light. This theory was proved experimentally by Robert Andrews Millikan in 1915.

There are many applications of the photoelectric energy, in case of solar power, when a photon strikes a photocell, it knocks an electron from the valance band to the conduction band of the atoms in the photocell material. An n-tyype semiconductor contact collects the electrons from the conduction band as electricity. The electrons lose energy as they do work outside the system, and are then returned to the solar cell via a p-type semiconductor contact. So it is useful for a for a variety of applications.

Then how solar photoelectric energy works at home?

Solar energy can be brought to a home through the installation of solar panels that contain photovoltaic cells. This is how a solar energy system works: Solar cells collect energy from the sun, which is converted to DC (direct current) electricity. An inverter converts the DC electricity into AC (alternating current) electricity. The converted AC electricity is added to your utility company’s electrical grid and you are credited for it.

A bi-directional power meter shows your home’s power consumption. When your solar system generates more energy than you use, the power meter moves backward to show negative power consumption. When your home uses more energy than your solar system has generated, the meter moves forward as it normally would and you will owe money to the power company.

There are many advantages of solar photoelectric energy, it provides a way to decrease your dependence on non-renewable fossil fuels. In areas with warm climates, a home solar power system can generate a large portion of the electricity used in the home and reduce your dependence on your local power utility. You will be protected from spikes in energy costs. An additional benefit of solar power comes in the form of federal, state and local tax credits and other financial incentives. A solar power system can also increase the resale value of a home. Perhaps the most important benefit of a home solar power system is that solar energy is clean and non-polluting. Solar power protects the environment and reduces greenhouse gases.

Electricity generated from solar power makes up a growing portion of the worldwide power generation market.

Solar power is electricity that is generated from sunlight, and is a common choice of renewable energy for households and for large companies. There are two basic forms of solar power in current use: photovoltaics and solar thermal power.

Photovoltaic systems, such as conventional solar panels, directly convert sunlight into energy using the principles of the photovoltaic effect. The photovoltaic effect takes advantage of the properties of semiconductor materials, with silicon being the primary material used in photovoltaic solar cells. When photons strike the solar cell, electrons in the semiconductor material are shaken loose, allowing them to flow as electricity. This electricity is direct current (DC), and can be directly used to charge batteries, or can be connected to an inverter to power alternating current (AC) components, or to be connected to the local electrical grid.

Traditional photovoltaic systems are based on silicon. Silicon ingots are sliced into wafers that are fabricated into cells. Cells are combined into modules, which are packaged into end-user systems. Silicon-based solar cells have efficiencies of approximately 14-19%. However, newer systems that use gallium arsenide, another semiconductor material, can be made into thinner and more flexible modules. These "thin film" modules can presently produce efficiencies up to 30%, but currently cost more to fabricate than traditional silicon-based modules.
