Q:How can I understand the working principles of solar cells?
Read as many books as you can.
Q:Can a solar cell be used in commercial buildings?
My apartment used solar cells as the main power supply .
Q:What is a monocrystalline Silicon Solar Cells?
According to the wikipedia, the monocrystalline silicon (or "single-crystal silicon", "single-crystal Si", "mono c-Si", or just mono-Si) is the base material for silicon chips used in virtually all electronic equipment today. Mono-Si also serves as photovoltaic, light-absorbing material in the manufacture of solar cells.
Q:Can the solar powered cells really work better than the normal cells?
The solar powered cells are absolutely better than the normal cells because the power is generating from the sunshine.
Q:Briefly explain why solar cells are made into components
The main photovoltaic material is the crystalline silicon material (including polysilicon and monocrystalline silicon), this material is high hardness, brittleness, uneven force easily brittle, exposed to the air easily oxidized, and the use of the process can not
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
It's not a easy job.
Q:Solar cell life for several years
Solar battery life of about ten years, the replacement is very convenient. Solar cells, also known as "solar chips" or "photovoltaic cells", is a direct use of solar photovoltaic power semiconductor thin film. As long as it is light to, and instantly can output voltage and in the case of a loop generated current.
Q:How is the solar cells factories working in China? Do they follow certain quality standards?
Yes, they follow the standard quality assurance protocol, and they are doing very well.
Q:Where can I buy the 156x156mm high efficiency poly solar cells assembly?
156x156mm high efficiency poly solar cells assembly is usually very easy to get, all you need to do is to post your need online, and the suppliers will come to you.
Q:What are the advantages of monocrystalline silicon and polycrystalline silicon in solar power?
single The wafer hot process time can be completed in less than one minute, using the process to make a cell conversion efficiency of more than 14% on 100 square centimeters of polysilicon wafers. It is reported that the current 50 ~ 60 micron polysilicon substrate produced on the battery efficiency of more than 16%. The use of mechanical groove, screen printing technology in the 100 square centimeter polycrystalline efficiency of more than 17%,
