In the solar battery that used silicon, the single-crystal silicon type solar battery and the polysilicon type solar battery were main currents before.
However, the number of cases into which the ordinary family introduced the photovoltaic generation increased considerably in recent years, and the influence existed, too the demand for the single-crystal silicon type solar battery decreased on the cost side, and a cheaper technology came to be requested.
Having given birth in shape to answer it is a thin film silicon type solar battery.
The thin film silicon type solar battery that is called an amorphous silicon type uses very thin “Film of silicon” as its name suggests.
The film of silicon is deposited to the glass substrate etc. , and the amount of silicon is suppressed to about indeed 1/100 compared with two of the crystal types by the method of using it as a base.
It will be able to be said that the thin film silicon type solar battery is a commodity in the silicon type solar battery whose expensive silicon is a problem on the cost side that achieves a very big cost reduction.
However, the electric conversion efficiency is inferior to two of other crystal types, and a figure named 7?10% while the cost side was considerably suppressed.
This conversion efficiency enters a considerably low class in the solar battery.
Therefore, when the solar panel is set up, the possibility that the amount of power generation hits a rough spot cannot be denied according to the environment and the area.
However, there is a merit that the irregularity of the amount of power generation only that the price is not suppressed like it by the temperature change also that is the weak point of the solar panel is suppressed to the minimum in the place where it seems to be a fault, too.
It will be able to be called a solar battery that attracts attention most in recent years.
