Solar energy is expected to become an unlimited renewable energy source in the future.This article will tell you how solar panels work and how to convert solar energy into electricity.
Solar energy is an energy source based on solar cell technology, which converts the energy obtained from the sun into electric energy.Solar panels are an array of solar cells that generate considerable power.
Considering that our planet receives about 1000 watts of solar energy per square meter, solar cell technology is expected to become the future energy source.However, it turns out that the low production cost and efficiency of solar cells is an obstacle for ordinary people to gain access to the technology.There is also a commitment that future research progress will make solar cells cheaper and accessible to ordinary people in developing countries.
As I said before, solar panels are an array of solar cells that are connected in series to generate electricity.First of all, understand how solar cells or solar photovoltaic cells work.
Name on photoVolts itself means that the cell converts the energy obtained from photons into electricity (volts ).There was a time when solar cells were used only for space applications to power satellites and space shuttles!With technological innovation and the entry of private enterprises, the production of solar cells becomes possible.They are now used to everything from calculators, cars to space ships.
Photovoltaic cells consist of special types of materials called "Semiconductors.The most widely used semiconductors are silicon and ge.They are insulators in a natural state.However, they can be converted into Conductive Materials by adding a small amount of doping elements.This doping semiconductor is used to build photovoltaic cells.
Let's see what happens when such solar cells are connected in a closed circuit and remain in the sun.This explanation is simple, a bit naive, but conveys the essence of the principle of operating solar cells.There are some technical details that I have not tried because this is for the lay audience.This will convey the key points of how solar panels work.
When photons fall on the surface of a solar cell, electrons in a semiconductor are knocked down or released by the absorption of energy.Each such photon is like a missile removing electrons from orbit around an atom.Each ray of sunlight contains millions of such photons that hit the semiconductor surface of a photovoltaic cell.
Each photon helps to free the electrons from the atomic shell.This creates a bunch of free electrons in semiconductors that can flow if an electric field is applied on a solar cell.This creates a tiny current on the semiconductor, which can be stretched for external use by using metal contacts placed on the surface.This current is weak and not strong enough.The efficiency of making the best quality solar cells is less than 30%.This means that 70% of the solar energy on these solar cells is not used.However, solar power is a huge breakthrough in itself.
In order to convert this small power output into a fairly large output, thousands of solar cell arrays come together to form solar panels.The electricity generated by each photovoltaic cell is combined through the series of these batteries in the panel.The combined voltage of the solar panel is output to the rechargeable battery and stored in the rechargeable battery for further use!The best thing about solar cells is that, unlike other sources of power generation, they generate electricity without pollution.In developed countries, solar energy is used more and more, but it still has a long way to go before it can break into the power hegemony of oil giants.
Solar energy is the way to green tomorrow!If the production technology of solar cells becomes cheaper, it can be produced and distributed in large quantities, which will reduce the dependence on traditional energy that is quickly consumed!
