Product Description:

Solar Cells:

solar cells, when struck by photons of light from the sun, generates an electrical current which can then be used to power DC or AC electrical loads.
A solar cell is made of silicon. Computer chips are made of this same material. Basically, when light strikes the surface of a solar cell some of it is absorbed into the silicon. This light energy bumps the electrons loose and causes energy to flow

Solar cells is made by solar wafer, it has three categories of solar cell right now, monocrystalline polycrystalline and thin film,These cells are entirely based around the concept of PN junction, which is the critical part of solar module, it is the part that can convert the light energy into electricity, the thickness is from 180um to 200um, with even busbars to conduct electricity, textured cell can decrease diffuse reflection; they are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting  semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current;With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Applications of solar cell

A solar 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.[2] 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 pv Modules: the application of solar cell

A PV module consists of many PV cells wired in parallel to increase current and in series to produce a higher voltage. 36 cell modules are the industry standard for large power production.

 

The module is encapsulated with tempered glass (or some other transparent material) on the front surface, and with a protective and waterproof material on the back surface. The edges are sealed for weatherproofing, and there is often an aluminum frame holding everything together in a mountable unit. In the back of the module there is a junction box, or wire leads, providing electrical connections.

There are currently four commercial production technologies for PV Modules:

Single Crystalline

This is the oldest and more expensive production technique, but it's also the most efficient sunlight conversion technology available. Module efficiency averages about 10% to 12%*

Polycrystalline or Multicrystalline

This has a slightly lower conversion efficiency compared to single crystalline but manufacturing costs are also lower. Module efficiency averages about 10% to 11%*

String Ribbon

This is a refinement of polycrystalline production, there is less work in production so costs are even lower. Module efficiency averages 7% to 8%*

Amorphous or Thin Film

Silicon material is vaporized and deposited on glass or stainless steel. The cost is lower than any other method. Module efficiency averages 5% to 7%*

 

 Solar Panels: the application of solar cells

Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:Why and what is the low efficiency solar cell?
The first thing we need to think about when the solar cells is becoming low efficient is to measured the reflectivity of the solar cells.
Q:Solar cell life for several years
Photoelectric effect of the work of thin film solar cells as the mainstream, and the implementation of photochemical effects of solar cells is still in the embryonic stage.
Q:Is it complicated to make a solar cell work well?
My chemistry teacher told me that as long as you have enough knowledge, you can make a solar cell work very well.
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:How does the photovoltaic cells work?
Photovoltaic solar cells fulfill two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity.
Q:What is a monocrystalline Silicon Solar Cells?
Monocrystalline photovoltaic electric solar energy panels have been the go-to choice for many years. They are among the oldest, most efficient and most dependable ways to produce electricity from the sun.
Q:Which one is better on the solar cells panel? The Monocrystal Solar Energy Cell or photovoltaic cell?
I tried both, and I noticed that photovoltaic cell is better at collecting the sunlight, which can be converted into the power supply I need. In this way, I think photovoltaic cell is the best!
Q:What is the window material in the solar cell? what's the effect?
Because the window layer near the surface, the defect is very much, if the absorption of light generated photogenerated carriers, then it is easy to die, do not contribute to the battery output, the absorption of light are wasted, reducing battery efficiency.
Q:Is there any easy way to make a solar cell? I want to make a DIY solar cell with my child at home.
If you know the principle of solar cells, it can be easy for you to make it yourself.
Q:My son is very interested in solar cells recently, and keeps asking me about the structure of a solar cell. Can anybody help me answer that question?
It's not shameful to tell your son that you have no idea, you can learn with him.
