The solar industry itself is an energy saving project. All solar energy comes from nature and is converted into electricity that can be used daily through professional equipment. In terms of energy saving, the use of solar energy systems is a very mature technological progress.
1. The expensive and long-term electricity bill no longer exists, and the electricity can be completely self-sufficient, which means that the cost of power supply is also less.
2. The storage and use of solar energy in emergency situations reduces too many risks, such as emergency reserve power for hospitals and emergency reserve power for households, there is no longer the risk of mains power failure, and the cost of power supply is also saved
3. Reduce the waste of resources caused by previous energy power supply, such as coal mine resources
With the depletion of non-renewable resources such as coal, oil, and natural gas, human beings urgently need to develop renewable clean energy. Solar energy has become the main form of future energy due to its outstanding advantages. Some solar products, such as solar cell lights, solar cell heaters, etc., are also well known to most people, but do you know about solar cells that can generate electricity around the clock?
Most people think that solar cells can only be used in sunny days, which is not true. With the deepening of scientists’ research on solar cells, solar cells that can generate electricity at night have been successfully developed.
The working principle of the “all-weather” solar cell is: when sunlight hits the solar cell, not all the sunlight can be absorbed by the cell and converted into electrical energy, only part of the visible light is effectively converted into electrical energy. To this end, the researchers introduced a key material into the battery to slightly increase the photoelectric conversion efficiency of the solar cell when the sun shines during the day, and at the same time store the energy of unabsorbed visible light and near-infrared light in this solar cell. material and release it at night in the form of monochromatic visible light. At this time, the monochromatic visible light is absorbed by the light absorber and converted into electrical energy, so that the solar cell can generate electricity both during the day and at night.
The research of this project makes our life no longer dependent on non-renewable energy sources, or resources with pollution risks. We do less damage to nature and improve our lives.
