Poly Solar Cells 156*156mm B Grade Low Price
A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
In contrast, a solar thermal collector supplies heat by absorbing sunlight, for the purpose of either direct heating or indirect electrical power generation from heat. A "photoelectrolytic cell" (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.

Brief introduction of 3 busbar solar cell
Solar cells, also known as "Solar chip" or "photovoltaic cell”, is a direct use of solar photovoltaic power generation semiconductor slice. As long as it is light that can be instantaneous output voltage and in the case of the circuit generates a current situation.
3 Busbar solar cell convert light into electrical energy through the photoelectric effect or photochemical effect directly. In the photoelectric effect of thin-film solar cells work for the mainstream, and to the implementation of the work photochemical effects of solar cells is still in its infancy.
Working principle of 3 busbar solar cell
Sun lights in the semiconductor p-n junction, forming a new hole - electron pairs in the p-n junction built-in electric field, the photo-generated holes flow to the p region, the photo-generated electrons flow into the n region, after turning circuit current. This is how the photovoltaic solar cell works.
There are two ways 3 busbar solar power working in, one is light - heat - electricity conversion mode, the other is light - electric direct conversion method.
Briefly, solar photovoltaic power generation principle is the use of solar cells to absorb 0.4μm ~ 1.1μm wavelength (for silicon) sunlight, light energy being converted into electric energy directly.
Since electricity generated by 3 busbar solar cells is DC, so if you provide electricity to all kinds of electrical appliances used in home or industrial need to install DC / AC converter, to change it into alternating current.
Most of the rechargeable solar cells apply in consumer products have charging problem. In the past general object takes charge NiMH or nickel cadmium batteries, nickel-metal hydride batteries but cannot withstand high temperatures and nickel-cadmium batteries have environmental pollution.
Super capacitor rapid development, large capacity, anti narrow area, coupled with low prices, it is part of the solar products began to shift to the super capacitor charging objects, thereby improving many of the problems of solar charging:
The long life of more than 5 times,
Charging a wide temperature range,
Reduce the amount of solar cells (which can be low voltage charging).
