The possibility of charging mobile phones using only solar energy in the future depends on the further development of solar technology. Solar power generation looks promising, but current solar power generation technology is not so satisfactory. Tian Yang's power generation technology was invented very early, but it has not been popularized until now. In addition to its great success, the most important thing is that the conversion efficiency is really not high and the conditions required for it. solar energy production is relatively high.
Currently, there are only two types of charging supported by all mobile phones on the market. One is wired charging, also known as wired charging, and the other is wireless charging, which is also now a technology that many phone manufacturerss mobiles are working hard to develop. Solar charging has definitely been included in the “development list”. After all, different cell phone manufacturers will definitely test all charging methods when developing charging technology. As for why solar charging technology was ultimately not used, there are only a few reasons. The first is safety issues, followed by cost issues and finally efficiency issues.
Solar panels absorb solar energy when producing electricity, so they generate a lot of heat. Over time, this heat is simply not something human hands can handle. If the heat generated cannot be dissipated well, then the cell phone is equivalent to a bomb, and the cell phone battery may explode at any time. Second, the cost of pansolar panels is not weak. The cost is much higher than that of the cables needed for charging. In addition, the conditions for solar energy production are relatively difficult. That it can be used in cloudy weather.
The last problem concerns the power of solar charging. The conversion efficiency of solar panels is very low. Even the most cost-effective solar panels have a conversion efficiency of only 30%. . Therefore, from these three aspects, it is impossible for solar charging to become a mainstream charging method. As for whether it will fall into the eyes of mobile phone manufacturers in the future, it still depends on how far solar power generation technology can develop. the future.
Why can't cell phones be charged with solar energy?
There are solar panels on TVsMobile phones and most of their technologies are used in outdoor environments. , large screens and direct sunlight. Photovoltaic The conversion technology is immature, and the absorption rate of solar silicon wafers is low.
Although this type of mobile phone is creative, it is technically backward. It can be charged, but the use effect is not satisfactory. Therefore, it is not practical
Requirements for solar panels for charging mobile phones
1. The back area of the mobile phone is too small, which affects the efficiency of solar energy. panels;
< p> 2. The efficiency of solar panels is too low, only between 15% and 20%. If you want a 10 watt effect, you need at least 12 inches of area to achieve it, so it cannot be applied and is only suitable for special groups;
< /p>
3. When youIf you use solar panels for charging, you need to consider whether the output current of the solar panels is consistent.
1. Power size: Choose the appropriate power according to your own electricity needs. If it is used to charge mobile phones and small devices, the power should be between 5W and 20W; large devices such as vehicle-mounted cranes, its power should be higher.
2. Output Voltage: Different devices require different voltages for charging. Therefore, when choosing a solar panel, pay attention to whether its output voltage meets the requirements.
3. Matching Battery: To store solar energy, when purchasing a matching battery for a solar panel, note that the battery capacity and rated voltage must match the solar panel.
