Q:Can cold light make solar panels power
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
Q:Single crystal solar panels and polycrystalline solar panels
monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
Q:What is the main material for making solar panels?
The correct name of solar panels is solar photovoltaic panels, making its main material is monocrystalline silicon or polysilicon silicon, monocrystalline silicon silicon chip more crystalline silicon wafer photoelectric conversion rate is high, the price is also more expensive silicon wafer.
Q:The voltage and power problems of solar panels
In general, the charging voltage is 1.5 times the battery voltage as well, that is 12V battery pack, select the 18V solar panels just.
Q:How many solar panels have ah?
Classification of solar cells: Currently on the market of solar cells into amorphous silicon and crystalline silicon. Crystalline silicon can be divided into polysilicon and monocrystalline silicon. From the photoelectric conversion efficiency of the three materials is: monocrystalline silicon (up to 17%)> polysilicon (12 ~ 15%)> amorphous silicon (about 5%).
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:Composition and function of solar panels
Among them, for the electronic grade polysilicon accounted for about 55%, solar grade polysilicon accounted for 45%, with the rapid development of photovoltaic industry, solar cell demand for polysilicon growth rate higher than the development of semiconductor polysilicon, is expected to 2008 solar polysilicon
Q:What is the principle of solar panels to convert solar energy into electricity?
When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:Can solar panels be connected directly to motor?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on.
