What is the Solar panels ?
Now the conversion rate of the market - based solar panels is still low, only 16.5%. Some of the domestic products can achieve 17%, and other people in foreign countries have achieved 25%.
Researchers at Rensselaer Polytechnic Institute in 2008 developed a new coating that covered the solar panels to increase the sunlight absorption rate to 96.2%, while the sunlight absorption rate of ordinary solar panels was only around 70%.
The new coating mainly solves two technical problems. First, it helps the solar panels absorb almost all the solar spectrum. The two is to make solar panels absorb sunlight from a larger angle, thus improving the efficiency of solar panels absorbing sunlight.
Ordinary solar panels usually can only absorb part of the solar spectrum, and usually only work in direct sunlight absorption efficiency is higher, so a lot of solar energy devices are equipped with automatic adjustment system, to ensure that the solar panels and the sun remains the most conducive to the absorption of energy angle.
The working principle of the solar charger
The principle of the solar cell phone charger converts the energy of the solar energy into the electric energy stored in the solar cell charger.
In the battery, the battery in the solar cell phone charger will be able to charge the battery when it needs to charge the cell phone.
In the sun, the principle of solar mobile phone charger is through the conversion of light into electrical energy through the control circuit to the built-in storage battery, can directly convert light energy generated by the mobile phone or other digital products charge, but must depend on the solar luminosity, with no sun light, by alternating current convert the DC power and the control circuit to the built-in storage battery.
