Insulating paper for solar energy has electrostatic requirements. According to the data query, solar energy insulation paper has static electricity requirements. It is necessary to check if there is electrostatic attraction, because very few metallic materials are used in low quality films. rubbed, they will slide left and right; while high quality films will slide left and right when metal materials are used. Additionally, they have an electrostatic attraction and therefore do not slip when rubbed.
Can solar panels between 6V and 7V directly charge cell phones? What to do if it doesn't work?
What you are talking about should be a white board, TPE or TPT or something like that. Refer to the following Baidu encyclopedia for more details:

No, not only can it not be charged. , but it will also consume current, because the current of small voltage photovoltaic panels is small, and the mobile phone circuit alone is not enough to consume. It is generally recommended to use 4 watt photovoltaic panels to charge and equip them. with voltage stabilization modules.
If the voltage is too high, it will easily fail and burn the cell phone battery (even if the output current of the solar panel is not large).
Solar panels between 6V and 7V can charge a 6V battery. When fully charged, the voltage across the battery is close to the solar voltage and there is no virtually no charging current at that time. It is best to connect an ammeter in series for monitoring. When charging, the ammeter indicatese a high value. When the indicated value is close to zero, the charge can be considered complete. ?
Detailed information
Mobile phones generally use 3.7V lithium batteries. In this case, you can choose a solar battery of 'about 4 or 5 V to charge. the phone.
Nowadays, solar cells can be made flexible, just like a piece of paper that can be folded. The advantage is that they can be sewn into textiles, such as backpacks, hats, clothing, etc. , so that it can be used outdoors. To charge a mobile phone, if the capacity of the mobile phone is 900mah, an A4 paper size (8.5W) monocrystalline silicon battery board can be fully charged in one hour under sufficient sunlight.
It is recommended to use a power bank to charge your cell phone whenthat there is no sun, but there are few restrictions on its use. As long as you have an AA dry battery, you can charge your cell phone. cell phone at any time. However, for the sake of environmental protection, it is recommended to use Ni-MH rechargeable battery, which is very beneficial to environmental protection.
