How solar cell is made - material, manufacture, making, used, parts, structure, procedure, steps
A type of solar cell to fully meet domestic energy solar cell manufacturing has not as yet been developed, but solar cells have become successful in providing energy for artificial satellites. Fuel systems and regular batteries were too heavy in a program solar cell manufacturing every ounce mattered.
Solar cells provide more energy per ounce of weight than all other conventional energy sources, and they are cost-effective.
Only a few large scale photovoltaic power systems have been set up. Most efforts lean toward providing solar cell solar cell manufacturing to remote places that have no other means of sophisticated power. About 50 megawatts are installed each year, yet solar cells provide only about.
Supporters of solar energy claim that the amount of solar solar cell manufacturing reaching the Earth's surface each year could easily provide all our energy needs several times over, yet solar cells have a long way to go before they fulfill Charles Fritts's dream of free, fully accessible solar electricity.
Raw Materials The basic component of a solar cell is pure silicon, which is not pure in its natural state.
How to Start a Solar Cell Manufacturing Company |
To make solar cells, the raw materials—silicon dioxide of either quartzite gravel or crushed quartz—are first placed into an electric arc furnace, where a carbon arc is applied to release the oxygen. The products are carbon dioxide and molten silicon. At this solar cell manufacturing, the silicon is still not pure enough to be used for solor cells and solar cell manufacturing further purification.
Pure silicon is derived from such silicon dioxides as quartzite gravel the purest silica or crushed quartz. The resulting pure silicon is then doped treated with with phosphorous and boron to produce an excess of electrons and a deficiency of electrons respectively to make a semiconductor capable of conducting electricity.
The silicon disks are shiny and require an anti-reflective coating, usually titanium dioxide. The solar module consists solar cell manufacturing the silicon semiconductor surrounded by protective material in a metal frame.
The protective material consists of an encapsulant of transparent silicon rubber or butyryl plastic commonly used in automobile windshields bonded around the cells, which are solar cell manufacturing embedded in ethylene vinyl acetate. A polyester film such as mylar or tedlar makes up the backing.
A glass solar cell manufacturing is found on terrestrial arrays, a lightweight plastic cover on satellite arrays.
The electronic parts are standard and consist mostly of copper. The frame is either steel or aluminum. Silicon is used as the cement to put it all together.
The Manufacturing Process Purifying the solar cell manufacturing 1 The silicon dioxide of either quartzite gravel or crushed quartz is placed into an electric arc furnace.

A carbon arc is then applied to release the oxygen. This simple process yields silicon with one percent impurity, useful in many industries but not solar cell manufacturing solar cell industry.
A rod of impure silicon is passed through a heated zone several times in the same direction. This procedure "drags" the impurities toward one end with each pass.
At a specific point, the silicon is deemed pure, and the impure solar cell manufacturing is removed.
