I HIGHLY doubt that Lenovo has put solar panels with 24.3% efficiecy on the back of this, but I would like to be wrong.
Submission statement:
The laptop uses back-contact cell technology, which is slightly more efficient than typical solar panels. Lenovo says the panels on the Yoga Solar have a 24.3% conversion rate — higher than [the average of 21% ](https://css.umich.edu/publications/factsheets/energy/solar-pv-energy-factsheet#:~:text=Though%20the%20average%20efficiency%20of%20solar%20panels%20available%20today%20is%2021%25)— and can absorb ambient light, sunlight, or any light source above 0.3 watts, equivalent to an LED night light.
The environmental impact of laptop production, due to mining rare earth minerals for batteries, is not insignificant. Powering laptops with clean energy instead of electricity can offset some drawbacks of laptop production and the associated e-waste.
