Types of "solar cells"
Solar cells are divided into two main types, namely silicon semiconductor solar cells and compound semiconductor solar cells. Solar cells that use silicon semiconductor Which will be further divided into 2 types according to their characteristics, namely those that are in crystal form (Crystal) and those that are not in the form of crystals (Amorphous). There are 3 main types of silicon conductors that Thai people use as follows:
1) Single crystal solar cell
single crystal solar cell Monocrystalline or Single Crystalline (Mono Crystalline/Single Crystalline) looks like a square sheet arranged horizontally like tiling. with a silver line to conduct electricity which is considered the first type of solar cell to be created Although expensive, they are more efficient than other types of solar panels.
2) Combined crystalline solar cells
crystalline solar cells polycrystalline or multi crystalline (Poly Crystalline/Multi Crystalline) looks blue. with rainbow crystal It is a solar cell built on top of a single crystal solar cell.
3) Thin film solar cells
Thin film silicon solar cell or amorphous silicon (Amorphous) looks black. There may be some rails sometimes, a solar cell that is not very popular. It is mostly used in large farms. Or used with various small electrical devices such as calculators, watches, etc.
