For some time, man collected wood to meet his energy needs.Today, we use coal, hydrocarbon fuels and electricity generated by wind, water and atoms to meet our needs.The use of solar panels to produce energy is also increasing.Let's learn more.
When certain solids come into contact with light, it will freely set negative and positive charges in it, which in turn will produce electrical activity I.e., The current in them.Famous scientist Albert Einstein won the Nobel Prize in Physics for analyzing this phenomenon known as "photoelectric effect.The following section briefly explains how this phenomenon is achieved in the form of photovoltaic cells (solar cells) for power generation.Estimated 20-30% of the energy per household is used to heat water.If it comes from electricity or burning fossil fuels, it is better to use solar panels to produce it.Once these panels are installed, they can last for 25 years and there is little expense in maintaining them.
The typical solar panel for power generation contains 36 solar cells of different sizes, depending on the wattage or amperage of the panel.A sturdy aluminum panel is installed in a sturdy frame as a rest for solar panels.The output of electricity depends on the type of material that makes solar cells.For the manufacture of rigid solar panels are single-crystal or multi-crystal solar cells.
A single crystal solar cell is made of 1mm thick silicon wafers grown from a single silicon crystal.Solar panels manufactured using these high-efficiency solar cells generate more power than multi-crystal solar cells.
Multi-layer silicon crystal sheet for manufacturing polysilicon batteries.These are less efficient than single crystals.However, multi-crystal solar cells for rigid solar panels are cheaper than single-crystal solar cells.
Solar cells use the photoelectric effect to generate electricity.Pure Crystalline silicon is not a good conductor of electricity.Its electrons cannot move and carry charges freely.So the atoms of other elements are added to 99.999% pure silicon.When added to silicon, elements such as boron convert it to P-Easy to accept electronic silicon type.On the other hand, when added to silicon, elements such as phosphorus convert it to N-Easy to provide electronic silicon type.
Solar cells, also known as photovoltaic cells, use P-Type N silicon layerSilicon layer and transparent conductive layer.It also has a metal contact layer and P-N junction.When the sun falls on the silicon layer of the solar cell, the electrons and positive charges (protons) are excited and begin to move within the layer (where N-Type and P-type receives).This electronic flow is called current.These moving charges are then channelized to the junction box by the electrical contacts placed on the solar cell and appear as a DC (DC) for charging the battery.The DC is fed into the inverter, which converts it into AC power that can be used to power electrical equipment.
In the northern hemisphere, solar panels must be facing the south, while in the southern hemisphere, solar panels must be facing the North to maximize the use of existing sunlight.The power generation is measured in kilowatts, of which 1 KW is equal to 1,000 watts.On a clear day, solar energy (sunlight) shines 1 square meter on the Earth's surface, potentially generating 1,000 watts of electricity.Efficiency of solar panels from 5-18% mainly depends on the type of solar cells used therein.Under laboratory conditions, moreThe efficiency of the solar cell has reached 40%.The intensity of sunlight, clouds, rain and snow is the main factor affecting the power generation of solar panels.
They are made by laying a layer of silicon on both sides of thin and transparent sheets of various materials.The film is layered with P-solar cellsSilicon type on one side and corresponding N-Type the silicon layer on the other side.The arrangement of the sheets is that the sun that falls on it passes through N-Type silicon layer, transparent film, and then reach P-Silicon Layer type.This stimulates electrons and protons and generates electrical activity, generating an electric field around the middle sheet.The current begins to flow through the conductive sheet.Solar panels made using this technology are light and easy to handle.The method of making these solar cells is cheap and will not waste precious Silicon when making them.These solar cells are made of amorphous silicon.
Scientists at the New Jersey Institute of Technology (NJIT) have developed a technology that uses carbon nanotubes that can be applied to flexible plastic sheets or printed on flexible plastic sheets to make solar cells.They believe that walls or roofs of houses painted with these cheap solar cells can be used as solar panels to generate electricity and then stored in rechargeable batteries for personal use.
Scientists at the Massachusetts Institute of Technology (MIT) have developed a new way to generate electricity using solar energy.Thermal photovoltaic (TPV) is solid-Use two layers to convert the state equipment of radiant heat from light sources such as the sun.Mirrors are used to collect and concentrate the sun on the top floor of the TPVs.The top layer consists of a photon crystal, which is designed to prevent the absorbed energy from leaking into the atmosphere, but it allows it to leak to the (photovoltaic) layer below.The Heat captured is used as the most suitable wavelength light emission for photovoltaic conversion.Solar TPV devices are more efficient than traditional photovoltaic solar cells, and up to 36% of solar energy is allegedly converted into electricity.Although these devices are recent developments, there is no large scale yet.Their production or commercial use represents a huge achievement in the use of solar energy.
Solar energy was once a high field.Pioneer of space vehicles-The No. 1 launched in March 17, 1958 was the first to use solar panels.Now scientists are experimenting with consumer cars.They are trying to convert the roof of these cars into solar cells with solar panels and make solar cells with carbon nanotubes.The world is trying to turn as much of the safe and free solar energy as possible into electricity.
