Apple could be planning to embed solar cells beneath its touchscreens, according to a new patent. The firm was recently granted a US patent for solar panel technology hidden beneath touch-sensitive surfaces, like those used in a Macbook trackpad, iPhone, iPad or Apple Watch display. According to the patent filing, the hidden solar panel would recharge the device throughout the day. Unfortunately, the Apple patent is very vague about the technology – which could provide a welcome battery boost to the firm's slew of power-hungry devices.
