A few days ago, Saudi Arabian scientists have developed a new type of ultra-thin solar cell without precious metal indium. Although its efficiency is not as good as that of traditional silicon solar cells, its flexibility and plasticity are slightly better than that of traditional silicon solar cells. According to the experiment, the new ultra-thin […]

What is the difference between linear regulated power supply and switching power supply
Linear regulated power supply changes and controls the output voltage and current by changing the conduction degree of the transistor. In linear regulated power supply, the transistor is equivalent to a variable resistor, which is connected in series in the power supply circuit. Because the variable resistor and the load flow through the same current, […]
The integration of battery and screen is leading the new trend of intelligent speaker development
After three years of rapid development, the development speed of China’s smart speaker market is slowing down. According to the data of runto, in the first half of 2020, the sales volume of China’s smart speaker market was 18.84 million units, with a year-on-year growth of 18%, far lower than the growth rate of over […]
