This type of calculator uses weak solar cell components, which are thin-film solar cell components. The part you see is only the power generating battery component. There is also a battery-like component inside that is used to store electricity. energy. It is not suitable for long-term use. Finally, this part has aged and deteriorated, just like a laptop's lithium battery will be damaged if not charged or discharged for a long time, and it is probably beyond repair. Replace it with a new one or wrap it in newspapers and put it in the refrigerator to see if it can be activated. . . The possibility is estimated to be very small.
It is not recommended to expose this electronic product to sunlight.
Because different calculator models, battery types and sun intensitywill affect the results. Generally speaking, ultraviolet rays from the sun can be converted into electrical energy, but this process is very slow and takes a long time. According to some experimental data, if an ordinary electronic calculator is exposed to sunlight for a whole day (about 12 hours), it can only obtain a small amount of energy, which is not enough to operate the calculator properly . Additionally, the situation would be different if solar cells were used as the power source for the calculator. Solar cells can convert solar energy directly into electrical energy with higher efficiency. However, even solar cells require a certain amount of light and time to generate enough power. Overall, there are several factors to consider when trying to calculate how long a computer will taketor to be exposed to sunlight before being powered, and the results are usually trivial.
Therefore, it is not recommended to expose the calculator to sunlight for long periods of time to avoid damage to its internal circuitry or battery.
