Would you like a solar cell phone? Is technically possible but unlikely

• Solar phones can produce only a small amount of energy to fill the devices
• Placing a solar panel on the back of the phone requires compromises, such as thicker or smaller battery or wireless charging
• Solar panels are fragile and if they are covered with a protective cover, their ability will decrease and even lose their target
• Direct sunshine for solar panels is good, cell phones are bad
• The use of solar panels has too much compromise and too little benefits

Sunlight is available in many parts of the world and is practically free. The disadvantage is that even the best available solar panels can only utilize about a quarter of the incoming energy. In practice, this represents about 240 W per square meter, so a Samsung Galaxy S25 Ultra-sized solar panel would produce up to 3W. Androidpolice.

Marketing pull is better than a useful accessory

Infinix’s solar telephone concept does not produce more than 2W even with high-efficiency cells. By comparison, the full charge of a 5000mAh phone battery will take more than nine hours with a power supply of 2W, assuming perfect efficiency. Even cheaper Samsung Galaxy phones support 25W wired charging. A built -in solar panel cannot replace wired or even wireless charging. Although it can be slowly uploaded to a standby phone, but for this, the Perovskit cells used by Infinix may not be the best. Although extremely effective, they degrade much faster than their silicon -based competitors.

Another problem is that the solar panel requires direct sunlight to achieve peak performance. It does not produce significant energy in the shade and it may not work in indoor light. There are solar panels optimized for indoor use, but they are expensive and their energy production is in the microwatt range. It is even a significant difference in the angle of light the light reaches. In other words, a built -in solar panel would rarely upload the phone to full capacity.

Do you need solar panels on your phone?

Placing the solar panel on the back of the phone leads to a long line of compromises. First of all, the manufacturer must squeeze the cells by making the phone thicker or forced to use a smaller battery. Wireless charging is not possible when the solar panel is on the way. Then you have to deal with durability. The solar panels are fragile, and if they cover them with a protective cover, their ability will decrease and even lose their goal.

Even if your phone manufacturer solves these challenges, you certainly don’t want your phone to spend a lot of time strong in direct sunshine. Heat is an enemy of healthy batteries. Although new battery technologies are more resistant to this, current lithium-ion compounds are poorly with extreme temperature. If the phone is exposed to the scorching rays of the sun, it almost guarantees shortening its life.

Despite the obstacles, some companies have already launched solar phones. In 1997, Nokia was a pioneer in the concept. The 1610/1611 model was optionally replaced with solar battery. Samsung launched the E1107 and S7550 in 2009 and LG the GD510 pop. Each had a built -in solar panel on the back.

More compromise than advantage

You can make a day -to -day phone technically. However, since no company has tried such a thing lately, this suggests that user interest may have been low. The idea is new, but the customers were not attracted to the fact that solar panels produced little energy. Samsung models reached about 10 minutes of telephone time from one hour charge. The solar function was intended to provide supplementary energy if necessary, but had little effect on everyday use.

There are many practical applications of solar energy. However, the installation of solar panels into smartphones or most other gadgets does not make sense with today’s technology. There is too much compromise and too little advantage. To a concept such as Lenovo’s solar laptophas a better chance of success, thanks to the larger surface and thus the greater performance, but it is also more of a borderline.

On this course, solar panels do not promise much good to have a longer lifetime phone batteries They’re here. Innovative battery technologies offer more energy density and some commercially available phones already use them. Silicon-carbon chemistry allows 6000 mAh charging to fit on a phone thinner than 9 millimeters. In addition Androidpolice.
