What are the advantages and disadvantages of solar cells and ordinary batteries?

There are two main types of solar cells ! The main material of crystalline silicon solar cells is silicon wafers, such as laying on a large area of solar cell curtain wall, because too much silicon wafers are used, the appearance will not look good. However, the conversion efficiency of crystalline silicon solar cells is twice as high as that of thin film solar cells. The conversion rate of crystalline silicon solar cells is 16% to 17%, thin-film solar cells is only about 8%, so for the time being, crystalline silicon solar cells are more marketable, but the future is not necessarily.

Relative to ordinary batteries, although there is a lack of environmental protection (although the so-called environmental protection) shortcomings of ordinary batteries.

But the advantage is that ordinary battery technology is relatively simple, and the manufacturing process is not very complex, and there is no monopoly in the field of technology!

At present, solar panels are mainly used in silicon and this thing of high purity 6 9 is 99.9999% of the silicon technology is monopolized by Germany, Japan and the United States of America, several companies, so the domestic need for high-end solar cells with silicon are imported and very troublesome

Also, I do not know what type of ordinary batteries you are referring to, ordinary batteries should be divided into nickel-metal hydride, Ri-electricity, carbon and alkaline. Alkaline and so on...
