silicon solar cell open circuit voltage
The Sun is the source of life on our planet. It? S not only the source of light but also the source of heat and other forms of energy. Even the energy stored in our food, fossil fuels, all these are actually the previous results of heat stroke? (sun). Probably that? S why the ancient civilizations used to worship the sun as a god. It? S amazing to know that an hour of solar energy, if fully exploited, can play a full year of energy need on earth!
How does solar power work?
Sunlight reaching the earth? S-shaped surface of:
1. the visible light or radiation (frequencies that produce spectra? violet to red? as it passes through a prism)
2. Heat or infrared frequency invisible radiation (below [= below] red spectrum)
3. High frequency of ultra violet radiation (frequencies beyond [ultra =] violet spectrum). The use of light needs no elaboration. Heat is the energy we use to dry clothes, run the water cycle (evaporation, cloud-rain). The UV is that it makes tanning the skin or causes of skin cancer.
But the way light is used in another way now-a-day, so that has opened on the new horizon renewable energy, solar electricity. This process of converting light into electricity is called PV or photovoltaics.
How solar cells or panels solar work?
Solar Cells convert light directly into electricity. On a sunny day, electrical energy converted from an area of 1 square meter can supply a 100 watt bulb light. Solar cells or photovoltaic cells are generally based on silicon (silicon is an element from sand) pieces absorb sunlight.
One end of Silicon (Si) piece is doped with boron (B), which is considered positive (+ VE) end and the other end is doped with phosphorus (P), which is negative (-ve) end. When light falls on the solar cell, electrons are displaced from the silicon atoms. However, the electrons tend to move the match that attracts electrons (negative charges). Therefore, there is a surplus of electrons? Final sees and the scarcity of electrons in the extreme + ve.
If a conductive line formed outside the cell between the + ve and? ve ends, an electric current is generated and a working circuit is built. This electricity is a current continuous or DC (unidirectional flow) as a battery. But DC is not suitable for common use, so it is converted to DC through an inverter? to alternating current or alternating current. This current can be transformed into necessary? Voltage? by a? transformer?.
This process of converting sunlight into electricity is called the process PV. A combination of photovoltaic cells makes a photovoltaic panel, a set of photovoltaic modules to form a photovoltaic panel or panels commonly called solar. Even more power can be achieved through a collection of photovoltaic panels together in a matrix?.
The chain of solar energy utilization
Summarizing all this, here is the chain of Solar Energy:
a. The sun radiates light
b. Photovoltaic cells convert solar radiation in the electricity
d. This electricity is like electricity generated by the battery (one-way flow of current) or DC.
e. The inverter converts direct current (DC) into alternating current (AC).
f. The guarantees that the processor voltage electricity from the investor is right for us.
g. The distribution scheme receive electricity generated by the system and combines it with other sources of electricity.
h. There can be no electric meters to measure the amount of electricity produced.
