Solar panels are solar devices that absorb solar radiation and convert solar radiation directly or indirectly into electrical energy by photoelectric effects or photochemical effects. Most of the solar panels are "silicon", but the cost of production is So that it can not be used extensively and widely. Compared to ordinary batteries and recyclable rechargeable batteries, solar cells are more environmentally friendly green products.
"Silicon" is one of the most abundant materials on our planet. Since nineteenth century scientists have discovered the semiconducting properties of crystalline silicon, it almost changed everything, even human thought. At the end of the 20th century, our life can be seen everywhere "silicon" figure and role, crystalline silicon solar cell is nearly 15 years to form the fastest industry.
The production process can be divided into five steps:
a, purification process
b, pull the bar process
c, slicing process
d, the battery process
e, the packaging process.
