Investment funds, the most taboo is to use the means of value investment to analyze a fund, but use short-term methods to trade, frequent short-term trading, but only brought rich fees to brokers. Short-term trading and band operation are not much more difficult than long-term investment. Even if you are lucky, you can only make a little profit.
In the future, with the development of technology, photovoltaic power generation and wind power generation are clean energy sources. The downward trend of prices in the future is obvious. By then, the advantages of photovoltaic and wind power will be further reflected in the use of energy storage to store excess electricity every day for future use, and the goals related to energy storage will also overlap in photovoltaic indicators.
Principle of photovoltaic power generation
The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. When a photon strikes the surface of a metal or semiconductor, its energy can be completely absorbed by an electron in the metal or semiconductor. The energy absorbed by electrons is large enough to overcome the internal attraction of objects and leave the original surface to become photoelectrons. The current formed by photoelectrons is called photocurrent.
Many people think that photovoltaic power generation is solar power generation, but it is not. The relationship between them is that photovoltaic power generation is only one kind of solar power generation, and solar power generation also includes photochemical power generation, light-induced power generation and photobiological power generation.
