Q:Where can I get the most accurate information about solar cells?
A authorized science book talking about solar cells could be a good reference.
Q:Do you believe you can make a solar cell by using kitchenware?
Really? Can you show me how?
Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
We used the poly solar cell which is the 125mm size, which is good enough for our usage in the lab.
Q:Can the solar powered cells really work better than the normal cells?
Because of the different ways of generating the power, the solar powered cells definitely better than the normal cells in the modern world.
Q:What is the best way to deal with surplus solar cells abandoned after burning?
The surplus of solar cells can be very useful or useless at all. Totally depend on how people try to apply it to the new construction work.
Q:How about the solar cell 156mm Mono-Crystalline?
The detailed measurement of the mono solar cell is Format: 156mm*156mm±0.5mm and Thickness: 200μm±20μm
Q:How to define the poly solar cells as the A Grade one?
You can try to define it through the three factors: Efficiency, stability and durability.
Q:What is the accurate explanation for the sun solar cell power system? How does it work?
The sun solar cell power system work in following way: Solar cell module can convert solar energy into electrical energy, and solar energy charging and discharging control device as a central control device.
Q:Why and what is the low efficiency solar cell?
Sometimes the solar cells made of bad quality silicon can cause the result that the solar cells you are using is lower efficient than when you started to use it. You might need to change some materials.
Q:How to manufacture solar cells?
If you want to know more about photovoltaic cell manufacture, you should look on Wikipedia.
