Q:What is the difference between polysilicon and monocrystalline silicon photovoltaic cells?
Monocrystalline silicon cells with high battery conversion efficiency, good stability, but the higher cost. Polycrystalline silicon cells are less costly and slightly lower in conversion efficiency than straight-drawn monocrystalline silicon solar cells, with various defects in materials such as grain boundaries, dislocations, microdefections, and impurity carbon and oxygen in materials, as well as tarnished during process Transition metal.
Q:Is that true that the price of solar cells will be reduced in the coming year?
There are some policy change from the central government that financial subsidies of purchasing solar cells from the government will be lowered compared to last year. This could be a big reason for the price going down.
Q:What can be used as the materials for solar cells?
As far as I know, silicon is used as the material for solar cells.
Q:How to manufacture solar cells?
Quality control is important in solar cell manufacture because discrepancy in the many processes and factors can adversely affect the overall efficiency of the cells.
Q:What is the window material in the solar cell? what's the effect?
The general window layer to play with the battery body layer to form the role of electric field within the pn junction, if the battery body layer is N-type, the window is p-type, and vice versa.
Q:Which Solar Panel Type is best? Polycrystalline panel or PV Module Monocrystalline Solar cell panel, or thin film?
The Monocrystalline silicon solar panels requires less space to operate, so it is one of the best if you don't have a huge space to install it.
Q:How to explain to students how the solar cells are made?
You'd better explain it step by step, following the lab experiments.
Q:Are bulk solar cells better than the normal solar cells?
Yes, the bulk solar cells are better than normal solar cells because its power supply is bigger than the normal solar cells.
Q:Does the solar cell generate electricity in the absence of the sun, only in the case of strong lights or lasers? If you can achieve how much, and the same day?
Sunlight is a composite light, in which only the frequency is greater than the solar cell threshold photons can effectively stimulate the solar cell power generation.
Q:24V 200W solar cells can charge 12V battery?
According to your battery and wiring box to see the line, 1 feet corresponding to 2,3,4 feet voltage is 12V, 24V, 36V, if the box in the line, you can choose from 1,3 out, but this is the All the way the battery is in a state of idle, a little waste Oh. It is best to use a 24V controller, which is more efficient.
