What is Soler power

Solar energy is the technology used to harness the sun energy and make it useable. As of 2011 the technology produced less than one tenth of one percent of global energy demand.

Many are familiar with so-called photovoltaic cells or solar panels, found on things like spacecraft rooftops and handheld calculators. The cells are made of semiconductor materials like those found in computer chips. When sunlight hits the cells it knocks electrons loose from their atoms. As the electrons flow through the cell, they generate electricity.

How to make solar panel:

A solar panel while rugged and durable in its finished form requires a complex and very technical process in its production.
In traditional solar modules polycrystalline and monocrystalline silicon wafers are impregnated with impurities to create a semiconductor that converts sunlight into electric current. Electrical contacts are then created to join one solar cell to another. As silicon reflects an anti-reflective coating is placed on top of the silicon wafers usually titanium dioxide or silicon oxide.
The solar cells are laid between a superstrate layer on the top and a backsheet layer on the bottom. The superstrate is usually glass and the backsheet is plastic. This is then placed inside an aluminium frame to create a finished solar panel
In thin film solar panels its a different process. It begins with a thin layer of flexible substrate such as coated glass stainless steel or plastic and metal contact and the solar cell is then built up in a series of layers. An oxide layer is then applied at the end to form the electrical contact of the cell. The cell is then laminated with a weather resistant superstrate material.
