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 laptop is a concept PC showcased by Lenovo which can achieve an industry-leading solar conversion rate of over 24%.

Lenovo brought concept laptops with 3D screens, foldable OLED, and solar panels to Mobile World Congress, along with new ideas for 3D gestures and AI accessories.
