Solar battery: photovoltaic theory and solar cell production

Welcome!

This site will be interesting and useful for people who interested in photovoltaic and for professionals in this field. The principle of solar energy transformation into electricity and mechanisms of power loss were explained in the theory section. The conventional technology of silicon solar cells production was described in the technology section. This site also contains information about principles of measuring and electroluminescence, their examples and explanations. Also you can find solar cells application examples.

The raw material is boron doped "solar" silicon wafer with resistivity in 0.5-3 Ohm*cm, thickness in 200 mkm and 125х125 mm or 156х156 mm dimensions. The following steps should be done to produce solar cell: saw damage etching, texturing ... read more

The silicon solar cell will emit weakly infrared light if it connects to the power supply. This illumination can be registered by IR sensitive camera. It is used for solar cells defect detecting.
So the electroluminescence makes it possible to detect and distinguish most defects of solar cell (cracks, micro-cracks, fingers interrupts, low efficiency regions, higher series resistivity, low lifetime regions, short circuit, regions which ... read more

The measuring photoelectric parameters of solar cells and modules is a necessary step of it production. It is made under AM1,5 spectrum light with light power of 10000 W/m². The current-voltage characteristic (I-V curve) is obtained by ... read more

Of course, generally solar cells are used for solar modules production. The solar modules can be used for different purposes.

The most part of solar modules are used for solar electric power plant building. Also it used for autonomic system of power supply and for ... read more

There are two types of solar chargers: with build in accumulator and without one.

The solar charger with build in accumulator is rather additional accumulator with possibility to charge themselves from sun. Usually it charges from network before journey to charge mobile phone after some time. Most this “solar charges” has very ... read more
