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.

A solar cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Solar cells are forms of solar modules, themselves coupled into even bigger units known as solar panels or chopped into chips . Just like the cells in a battery, the cells in a solar panel are designed to generate electricity; but where a battery's cells make electricity from chemicals, a solar panel's cells generate power by capturing sunlight instead. They are sometimes   called photovoltaic (PV) cells because they use sunlight to make electricity.

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 "photo electrolytic cell", on the other hand, refers either to a type of photovoltaic cell, or to a device that splits water directly into hydrogen and oxygen using only solar illumination.

In general, a solar cell that includes both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photo generation of charge carriers in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.

There is more about the different types of solar cell here. The nominal output voltage of a solar panel is usually 12 Volts, and they may be used singly or wired together into an array. The number and size required is determined by the available light and the amount of energy required.

We can think of light as being made of tiny particles called photons, so a beam of sunlight is like a bright yellow fire hose shooting trillions upon trillions of photons our way. Stick a solar cell in its path and it catches these energetic photons and converts them into a flow of electrons—an electric current. Each cell generates a few volts of electricity, so a solar panel's job is to combine the energy produced by many cells to make a useful amount of electric current and voltage.

Virtually all of today's solar cells are made from slices of silicon, although as we'll see shortly, a variety of other materials can be used as well. When sunlight shines on a solar cell, the energy it carries blasts electrons out of the silicon. These can be forced to flow around an electric circuit and power anything that runs on electricity. That's a pretty simplified explanation!

Historically solar cells have been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth orbiting satellites, consumer systems, e.g. handheld calculators or wrist watches, remote radio-telephones and water pumping applications.

Solar cells are regarded as one of the key technologies towards a sustainable energy supply.

Q:
Yes, solar cells can be used in agriculture for irrigation. Solar-powered water pumps can be used to draw water from wells or other sources, providing a reliable and sustainable solution for irrigation. This helps farmers reduce their dependence on traditional energy sources and decrease operational costs, making solar cells a viable option for agricultural irrigation.
Q:
Yes, solar cells can be used in high-altitude areas. In fact, solar cells can actually be more efficient at higher altitudes due to reduced atmospheric interference and increased solar irradiance. However, the performance of solar cells can still be affected by factors like temperature and snow cover, which need to be considered for optimal utilization in high-altitude regions.
Q:
Yes, solar cells can be used to power remote data collection systems. Solar cells convert sunlight into electricity, providing a sustainable and reliable source of power for off-grid locations. This makes them ideal for powering remote data collection systems, allowing continuous operation without the need for a grid connection or frequent battery replacements.
Q:
Yes, solar cells can be used in hybrid systems. Hybrid systems combine different sources of energy, such as solar, wind, or fossil fuels, to generate electricity. Solar cells can be integrated into these systems to harness solar energy and contribute to the overall power generation. This allows for a more sustainable and efficient energy production, reducing reliance on traditional energy sources.
Q:
Yes, solar cells can be used for off-grid power systems. Solar cells convert sunlight directly into electricity, allowing them to generate power in remote locations or areas without access to the traditional power grid. They are particularly well-suited for off-grid power systems as they are reliable, renewable, and require minimal maintenance. Additionally, advancements in battery storage technology have made it possible to store excess energy generated by solar cells for use during periods of low or no sunlight, further enhancing their suitability for off-grid applications.
Q:
Solar cells are generally not designed to handle electromagnetic pulses (EMPs) directly. EMPs can cause a sudden surge in electrical energy, which can potentially damage or destroy electronic devices, including solar cells. However, solar cells usually have built-in protection mechanisms and are often shielded by other components in a solar panel system, such as inverters or charge controllers, which can help mitigate the effects of EMPs. Additionally, the impact of EMPs on solar cells can vary depending on factors such as the magnitude and proximity of the pulse, as well as the quality and design of the solar cell system.
Q:
Solar cells can still perform efficiently in humid climates. However, high humidity levels can slightly reduce the overall performance of solar cells due to the moisture in the air. The moisture can create a thin film on the surface of the solar panels, which reduces the amount of sunlight that can be absorbed by the cells. Additionally, increased humidity can also affect the electrical connections and can potentially lead to corrosion or damage over time. Nonetheless, advancements in solar cell technology, such as anti-reflective coatings and improved waterproofing, have helped mitigate the impact of humidity on solar cell performance.
Q:
Yes, solar cells can be used in desalination plants. Solar energy can be harnessed to power the desalination process, providing a sustainable and environmentally friendly solution to address the growing global water scarcity issue.
Q:How long does it take to make a solar cell?
It only took me 1 day because I had all the required materials ready before I start to make it.
Q:
Yes, solar cells can be used to power hospitals. Solar energy can be harnessed through solar panels or solar cells, and these can generate electricity to meet the power needs of hospitals. By utilizing solar power, hospitals can reduce their reliance on traditional energy sources, lower their operating costs, and contribute to a cleaner and more sustainable environment. However, the feasibility of using solar cells for powering hospitals depends on factors such as the hospital's energy demand, available space for solar panels, and the region's sunlight availability.
