Brief Introduction of Solar Cell

There has been tremendous growth in the worldwide renewable energy market with solar energy being a major part of it. 

An increasing trend has been observed in people who prefer clean energy produced from renewable sources rather than conventional non-renewable sources. 

The main reason for this transition is that electricity prices continue to increase, but environmental awareness by various government agencies and NGOs is also very important. 

Various solar devices are popular today, some of the most popular equipment are solar water heaters, solar stoves, and the most commonly seen solar cell street lamps (Also known as “ โคมไฟถนนโซล่าเซลล์ “ in the Thai language).

But the power of this device is a solar panel consisting of many small solar cells made of silicon. Let us in detail about this technology that will create a revolution in our energy system in the future.

Solar cells or photovoltaic cells are electrical devices, which convert sunlight energy directly into electrical energy by photovoltaic effects. This is a type of photoelectric cell. 

When exposed to light, it generates an electric current without taking the help of an external power source. 

The conclusion – without going into technical details is that light rays that fall on solar panels are captured by silicon, which then converts it into electrical energy through several chemical and physical processes.
