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.

It was the one of the type “Single-crystal silicon type solar battery” that was researched first in that situation though it was a solar panel by which it spread considerably now, and the kind also became abundant.
In the single-crystal silicon type solar battery, the wafer of the silicon monocrystal is made a base, and the point to take pride in a very high though it is the oldest solar battery conversion efficiency is a feature.
Therefore, efficiency of making sunlight electricity is high, and the share is considerably improving.
Moreover, it will be able to be said that reliability is also high because it has an old history.
However, it rises considerably in respect of cost of manufacturing because a very expensive material of silicon crystal is used on the other hand.
Naturally, it enters an expensive by all means class as a commodity because the sales price becomes improving compared with other solar batteries, too.
The point that it costs much somewhat becomes a problem as a solar panel that the individual buys though it is still good for the amount that the corporation uses.
Because the flow of cost reduction is remarkably seen in the field of the photovoltaic generation in recent years, the single-crystal silicon type solar battery is expected that the occupation rate will decrease gradually.
The cost reduction of the solar battery unit might be a reason why the point of difficulty is the maximum because it doesn’t go not to use the silicon crystal.
However, the historical value seems for the existence not to disappear even if being decline high in the future because of the fact that it is a solar battery by which the human race started it first.
All solar batteries with the number started here.
