Characteristics of solar cells of a single crystal :
Manufacturer - vikocell
Type - single crystal
Material - monocrystalline silicon
Maximum power 4.7 W
The size of the cell - 156x156 mm
Number of cells - 10
Voltage - 0.5 V
Solar cells - tool for converting solar energy into electricity. Produce them in silicon.
The first stage of processing - the fire. Sand passed through the furnace. Temperature reaches 2 thousand degrees. Since silicon is preserved in a liquid state. Then it was cooled, a special substance, which makes a conductive silicon.
When the reaction is complete, take out the substance. Future solar panel looks like a huge cube. It is cut. When blocks are ready, cut them into smaller parts.
Blue plate - is by necessity. Thus, the panel will absorb more of the solar rays. Further elements are covered with liquid metal. That he will conduct energy to the mains.
Solar cells produce two major types: monocrystalline and polycrystalline.
The material for the production of monocrystalline solar cells is an ultra-pure silicon, also used for the production of semiconductor devices in electronics.
Еlements on the basis of single-crystal silicon have an efficiency of about 22% at a life of about 25 years.
When slow cooling the silicon melt from it turns polycrystalline silicon, used for the manufacture of polycrystalline solar cells . Operation pulling silicon crystals from the melt is less labor intensive than the production of monocrystalline silicon, and therefore such solar cells cheaper.
The elements of a polycrystalline silicon have an efficiency somewhat lower than that of single-crystal panels. Guarantee the durability of these elements is approximately 10 years.
