Product Details

Zhongneng Chengyu Power Co., Ltd is a manufacturer of various solar energy system. Like monocrystalline photovoltaic electric solar energy panels have been the go-to choice for many years. They are among the oldest, most efficient and most dependable ways to produce electricity from the sun.Each module is made from a single silicon crystal, and is more efficient, though more expensive, than the newer and cheaper polycrystalline and thin-film PV panel technologies.  You can typically recognize them by their color which is typically black or iridescent blue.

How Monocrystalline Cells Are Made?


As the name implies this type of solar panel are unique in their use of a single, very pure crystal of silicon. Using a process, similar to making semi-conductors, the silicon dioxide of either quartzite gravel or crushed quartz is placed into an electric arc furnace. Heat is then applied and the result is carbon dioxide and molten silicon. This simple process yields silicon with one percent impurity, useful in many industries but not the solar cell industry, which requires a much higher purity level.


This is accomplished by passing a rod of impure silicon through a heated zone several times in the same direction. This procedure "drags" the impurities toward one end with each pass. At a specific point, the silicon is deemed pure, and the impure end is removed.


Next, a silicon seed crystal is put into a Czochralski growth apparatus, where it is dipped into melted polycrystalline silicon. The traditional way of adding boron, is to introduce a small amount of boron during the Czochralski process. The seed crystal rotates as it is withdrawn, forming a cylindrical ingot of very pure silicon.


Wafers are then sliced out of the ingot, then sealed back to back and placed in a furnace to be heated to slightly below the melting point of silicon (1,410 degrees Celsius) in the presence of phosphorous gas. The phosphorous atoms "burrow" into the silicon, which is more porous because it is close to becoming a liquid. The temperature and time given to the process is carefully controlled to ensure a uniform junction of proper depth.
