Lenovo has introduced the Yoga Solar PC Concept at MWC 2025, a laptop featuring built-in solar panels that utilize Back Contact Cell technology for enhanced energy conversion. Weighing 2.6 pounds and equipped with an OLED display, 32GB of RAM, and a 50.2 WHr battery, this laptop shows that advancements in solar technology can integrate into consumer electronics. Capable of gathering power even indoors, the laptop can play an hour of videos with just 20 minutes of sunlight. Despite its promising design, Lenovo currently has no plans for commercial release.
However, all those components aren't nearly as important as the solar cells embedded in its lid. Lenovo says the panels use Back Contact Cell technology so that its mounting brackets and gridlines can be placed on the rear of the cells.
The PC also supports Dynamic Solar Tracking to automatically adjust the cells' settings to maximize the amount of energy they can gather.
Lenovo says this means the Yoga Solar PC can generate enough juice to play an hour of videos after only 20 minutes in the sun.
Unfortunately, Lenovo doesn't have any plans to turn this concept into a full commercial device.
