Core logic: In the era of affordable Internet, cost reduction and efficiency increase are still the key factors to promote the further development of photovoltaic. Globally, photovoltaic has become the cheapest form of power generation in most countries and regions, realizing affordable Internet access on the power generation side. However, due to the intermittence, randomness …
Wireless lapel microphone, a type of wireless microphone, has become popular recently. It is a small, small and portable microphone, usually worn in the location of the user's clothing lapel. It can be freed from the cable, and the user can do whatever he or she wants without worrying about the sound. It is generally …
Solar cells are devices that directly convert light energy into electricity through the photoelectric or photochemical effect. The thin-film solar cell based on photoelectric effect is the mainstream, while the solar cell based on photochemical effect is still in its infancy. The sun shines on the semiconductor p-N junction, creating new holes called electron pairs. …
