suchSurfacePen will use solar cells to collect the light generated from the device displays that are paired with them, and then convert them into the energy charged for their built-in batteries. In the patent, Microsoft describes the solar cells in the pen. The company explains that the light of the screen is more effective than the rechargeable battery.

The Microsoft patent says that the stylus collects light when interacting with the touch screen, as the touch pen is very close to the touch screen during the harvest, and the intensity of the light collected from the electronic display is significantly higher than that of the indoor or outdoor lighting. Although solar cells are used internally, Surface Pen will not undergo much change in appearance, but will remain similar to existing models.

However, like all products that are still in the patent stage, we can not guarantee that Microsoft will eventually make them sell products on the market.
