Apparently, this figure was achieved by positioning much of the cell's support structure behind it, maximizing the available surface area for light absorption. There's a visible bezel around the edge of the solar panel on the lid of the laptop, but basically all other space is devoted to the actual sunlight-absorbing parts.

The company announced a thin-and-light solar-powered laptop at MWC 2025, and it's way more useful than I assumed. Here's how it works.

At Mobile World Congress (MWC) 2025 in Barcelona, Lenovo unveiled a groundbreaking innovation: the Solar Yoga PC, a laptop that charges itself by harnessing sunlight. This pioneering device marks a significant leap in sustainable technology, integrating advanced solar energy conversion features to extend battery life — even in low-light conditions.
