Gallium arsenide (GaAs) Ⅲ ~ V compound battery conversion efficiency of up to 28%, GaAs compound material has a very ideal optical band gap, as well as high absorption efficiency, strong resistance to irradiation, heat insensitive, suitable for the manufacture of high-efficiency single-junction battery. However, the price of GaAs materials is not expensive, thus limiting the popularization of GaAs batteries to a large extent.

Copper indium selenide thin film battery (CIS for short) is suitable for photoelectric conversion, there is no photoelectric recession, conversion efficiency and polysilicon, as with low prices, good performance and process simplicity and other advantages, will become an important direction for the future development of solar cells. The only problem is the source of materials, due to indium and selenium are relatively rare elements, therefore, the development of such batteries are bound to be limited.
(3) organic polymer solar cells
Organic polymers instead of inorganic materials is a research direction of solar cell manufacturing. As organic materials have good flexibility, easy to make, wide range of material sources, low cost and other advantages, thus the large-scale use of solar energy, providing cheap electricity is of great significance. However, organic materials to prepare solar cell research has just begun, whether it is the service life, or battery efficiency can not be compared with inorganic materials, especially silicon batteries, whether it can be developed into a practical significance of the product, but also to be explored in further research.
(4) nanocrystalline solar cells (dye-sensitized solar cells)
Nano Ti02, crystalline chemical energy solar cells are newly developed, with cheap cost and simple process and stable performance. Its photovoltaic efficiency stabilized at more than 10%, the production cost is only 1/5 ~ 1/10 of silicon solar cells, life expectancy can reach more than 20 years. However, since the research and development of such cells has just begun, it is estimated that they will gradually come to the market in the near future.
