Sony is exploring a future where PlayStation controllers may never need to be plugged in again. The tech and gaming giant has published a new patent outlining a self-charging controller powered by light—marking a potentially game-changing step toward sustainable, hassle-free gaming.
The patent, titled “Operation Device,” reveals Sony’s plans to embed photovoltaic elements—the same technology used in solar panels—into the structure of PlayStation controllers. These cells convert ambient light into electricity, which is then stored in a built-in power unit. That means if you’re gaming in a well-lit room or even just leave the controller in the sun, it could be silently recharging itself the whole time.
According to the document, Sony intends for the solar-powered controller to operate entirely without traditional power sources. “A plurality of photovoltaic elements disposed in a [controller], and a power storage unit for storing power generated by the plurality of photovoltaic elements,” the patent reads. “The photovoltaic element has a solar power generation function and generates electric power used by the [controller].”
This innovation could solve one of the most frustrating problems in modern gaming—controllers dying at the worst possible moment. Whether you’re deep in a boss fight or halfway through a multiplayer session, the sudden low-battery warning is a universal nuisance. Sony’s design not only eliminates the need for USB charging cables but also addresses environmental concerns tied to disposable batteries.
Images included in the patent show several proposed configurations for the solar cells, suggesting that Sony is exploring multiple design options. These variations indicate a serious effort to make the technology both functional and aesthetically seamless—ensuring the solar panels blend into the sleek design of the PlayStation controller rather than disrupt it.
While this doesn’t guarantee that solar-powered controllers will hit the market any time soon, Sony has a history of filing patents that eventually influence its consumer products. Just in the past year, the company has patented ideas for temperature-changing controllers and even modular designs for different play styles. The solar-charging controller appears to be one of the more practical and feasible concepts.
The move also fits into a broader trend in tech toward renewable energy integration. As devices become more power-hungry and consumers more eco-conscious, solar technology offers a compelling solution. Sony’s proposal could position the PlayStation brand as a leader in green gaming innovation—something no other major console manufacturer has yet seriously pursued.
Of course, several questions remain. Will the controller charge efficiently in low-light indoor settings? How much power can realistically be generated through these built-in solar cells? And would gamers pay a premium for a controller that rarely, if ever, needs to be charged?
Still, even as just a patent, this idea has sparked considerable buzz among fans and tech analysts alike. If Sony follows through on this innovation, we might be looking at the next big leap in controller design—one where players can game longer, recharge less, and say goodbye to low-battery anxiety forever.
