The thin film solar cells with light weight and thin thickness. It can be bent andeasy to carry. Because conventional silicon cells made of silicon crystals, the main part of the battery fragile, prone to cracks invisible, mostly as a layer of protective glass, resulting in a large weight, portable inconvenience, poor seismic capacity, high cost, efficiency is more or less reduced. thin-film solar cells to overcome these shortcomings, but not the high conversion efficiency of traditional silicon cells. conversion efficiency of thin film solar cell to enhance solar technology sector is currently being studied the main direction as yet fully mature, large-scale production is still some risk, but is bound to play an important role in the field of solar energy whose development prospects are very promising.
It is to change a thin film into a solar cell with a little silicon is extremely which is easy to reduce costs. Meanwhile, it is not only an effective energy products, but also a new building material which is very easy to connect perfectly with the building. In the context of the continuing tensions of international market of raw materials silicon, the thin film solar cells has become the development trends and hot spots of the international PV market .
The solar photovoltaic panels are divided into two kinds, the crystalline silicon and amorphous silicon. The thin?film amorphous silicon is one of the solar panels. The advantages of crystalline silicon solar cells: The technology is mature and the per unit area conversion efficiency is high(15% -19%); Disadvantages: The low light property is poor so it can only be made in fixed shape. The advantages of the amorphous silicon solar cells: The low light property is strong, and it can be made into any shape, especially for BIPV; Disadvantages: The technology is not mature, and the per unit area low conversion efficiency(up 9%) is low.
