Lenovo solar-powered Yoga PC at MWC 2025 in Barcelona

At MWC 2025, Lenovo introduces its solar-powered Yoga PC concept that charges itself by directly absorbing sunlight. The Mobile World Congress (MWC) 2025, a major wireless technology trade show, runs between March 3rd and 6th, 2025 in Barcelona. It is here that Lenovo brings what it calls the Solar Yoga PC. At the back of the device lie several solar cells. They come with the company’s Back Contact Cell technology. It basically moves mounting brackets and gridlines to the back of the solar cells to maximize the active absorption of sunlight.

The technology operates alongside the Dynamic Solar Tracking system, which constantly measures the solar panel’s current and voltage. Then there’s the Solar-First Energy system. It automatically adjusts the charger settings of the Lenovo solar-powered PC to prioritize transferring and converting the harvested energy into the device. The system saves the energy use of the PC as well as the continuous absorption of natural light even in low-light conditions.

Laptop that converts direct sunlight in 20 minutes

Lenovo says its solar-powered Yoga PC still generates energy even in conditions with minimal lighting. It allows the device to sustain its battery charge when it is in idle mode. While the device is still a concept, the company says that its solar panel features an over 24 percent conversion rate, which it believes is one of the highest in the industry. 

So far, the Lenovo solar-powered PC can absorb and convert enough direct sunlight in 20 minutes. This means it can power itself up to one hour of video playback on the device. The design team makes the computer 15 mm thin and just 1.22 kilos to make it slim and lightweight, so users can bring it anywhere. The company adds that because of these features, the Lenovo device ‘is the world’s first ultraslim solar-powered PC.’
