With The Vigorous Development Of Photovoltaic Power Generation, When Can We Drive Energy-saving And Environmentally Friendly Solar Cars?

In the 21st century, human science and technology are developing like a highway, but energy resources are also disappearing. And solar energy has also become a hot topic in the new century. The convenience brought by solar energy is increasingly entering people's lives.

In the field of technology, solar circuit boards are also receiving more and more attention. They have great potential to become low-cost renewable energy power generation technologies. Organic solar cells are composed of monocrystalline silicon, glass and polycrystalline silicon wafers. These three materials are processed through economical methods such as printing or coating. Solar panels can convert solar energy into electrical energy and output DC electricity. into the battery. Then someone raised the question: "Why not install solar circuit panels on electric vehicles? Wouldn't that not only save resources but also improve efficiency?"

This is indeed a good idea, and solar circuit panels are indeed a solution that is both safe and resource-saving. But as far as current photovoltaic technology is concerned, there is still a long way to go to realize solar electric vehicles.

The biggest reason is that the conversion rate of solar cells is too low, resulting in low charging efficiency. We assume that a pure electric vehicle can run 8 kilometers per kilowatt-hour of electricity, and only counting urban commuting. If it runs 40 kilometers a day, it requires 5 kilowatt-hours of electricity. However, the efficiency of a 200-watt polysilicon solar power generation panel in daily use is less than about 1/3.

Even if we go to a large scale and calculate the conversion rate as 50%, the area required to charge 5 kilowatt hours of electricity per hour is 5000w/200 peak watts * 0.5 conversion efficiency = 50 square meters of solar panel area. And this data is calculated based on a conversion rate of 50%. In fact, considering the existence of many problems such as light offset, this area will be even more exaggerated. Besides, the current cost of photovoltaic panels is not low, and it will take four to five years to get back the money. That's fine for buildings, but for pure electric vehicles, four or five years is not a short cycle.

Some people may say: "I will install a small solar panel on the car and use a mixture of gasoline and electricity to save a little money." This is not impossible. For example, Toyota's Prius plug-in hybrid model has a roof-mounted solar panel. plate. But based on the current conversion efficiency, you can't save much money. If you expose it to the sun for two or three days, it will only cost a few more hours, and it will also affect the appearance. The place to install the solar panels must be on the roof of the car, right? Then the position of the skylight was removed. I still believe that most people would prefer skylights compared to running around with solar panels for several hours to replace them. Not to mention factors such as wind and rain during actual use.

But there is no need to be discouraged. With the progress and development of photovoltaic technology, solar cars are getting closer and closer to us. Perhaps in the near future, mature photovoltaic technology cars will meet us unexpectedly.
