Q:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
I don't think it's lower than normal, 16.8% is pretty common in most of the power plants in my area.
Q:What diode does the solar panel use?
The main difference between the two diodes in the application of solar energy is the conduction voltage drop, the Schottky 0.4V or so, the ordinary 0.7V or so, mainly depends on your solar cell output voltage, if the solar cell voltage is lower than 5V or even 2V
Q:How to generate solar cells, the principle of PN junction
Salt, such as gallium arsenide III-V compounds, cadmium sulfide, copper indium selenium and other multi-compound materials for the battery; 3, functional polymer materials prepared by the large solar cells; 4, nano-crystal solar cells.
Q:What is Solar Cell Technology?
it is the technology focused in utilzing solar cells.
Q:How can I buy the solar cells wholesale ?
Please feel free to contact us, a solar cell production company based in Zhuhai, Guangzhou Province. We can offer you the best wholesale price with very good quality.
Q:The history of solar cells
The earliest lithium battery came from the great inventor Edison. As the chemical properties of lithium metal is very lively, making lithium metal processing, preservation, use, the environment is very high. Therefore, lithium batteries have not been applied for a long time.
Q:On the parallel connection of solar cells
if this group of bad The phenomenon of short-circuit, that the solar cells on the electrical equipment and output, but the voltage is reduced; if it is a parallel combination, then I suggest Each group of "output" line in series with a "switch" type of diode, so, if in which one of the short-circuit damage, other normal solar cells will not be bad on this group of "anti-charging" and Damage to other normal solar cells, if this group of bad conditions for the open circuit, it is only to reduce the entire solar cell "external" output current, will not cause other failures.
Q:How does the solar panel produce it yourself?
Titanium Dioxide Film The titanium dioxide powder was first put into a mortar and ground with a binder. The film was then slowly dried on a conductive glass with a glass rod. The titanium dioxide film was sintered in an alcohol lamp for 10 to 15 minutes and then cooled The
Q:How is the solar panel and the battery connected?
In the case of solar power to charge the battery at the same time, the battery power supply is completely feasible, in this case, the load will use the power of electricity directly to the use of solar cells, the remaining charge to the battery; the contrary, if the solar battery power is not enough , Will also take electricity from the battery at the same time.
Q:Is the polymer solar cell the cheapest type among all the different kinds of solar cells?
Yes, they are cheaper because of lower manufacturing costs.
