Lenovo made waves at this year's Mobile World Congress (MWC) 2025 by introducing a groundbreaking laptop concept featuring built-in solar panels—a design that blends practicality with sustainability.

Showcased at MWC 2025 in Barcelona, the Yoga Solar PC is a prototype laptop equipped with solar panels on its lid, allowing it to recharge using sunlight. This innovative approach offers an eco-friendly and convenient solution for users who need power on the go.

The device incorporates advanced Back Contact Cell technology, which maximizes solar energy absorption, even in low-light conditions. Lenovo claims that with a solar energy conversion rate exceeding 24%, just 20 minutes of sunlight exposure can provide an extra hour of video playback. Users can track real-time energy absorption through a dedicated app to better manage battery life. Beyond its solar capabilities, the laptop functions as a standard 14-inch notebook.

A Step Towards Energy Independence

Integrating solar panels into a laptop marks a major leap forward in portable device autonomy, addressing the increasing demand for sustainable, off-grid computing solutions. However, Lenovo has yet to confirm if or when the Yoga Solar PC will be released commercially, leaving uncertainty about its potential for mass production.

Another Innovation: The ThinkBook Flip

Lenovo also unveiled another cutting-edge concept, the ThinkBook Flip, which features a flexible OLED display that can fold outward, transforming a 13.1-inch laptop into an 18.1-inch vertical screen. This adaptable design supports multiple usage modes, including laptop mode, tablet mode, and reading mode.

Additionally, the ThinkBook Flip integrates AI-enhanced features to boost productivity. However, Lenovo has not provided details on whether this futuristic device will become a commercially available product in the near future.
