The utility model discloses a printing carrier plate and a photovoltaic cell, and belongs to the technical field of photovoltaic cells. The printing support plate comprises a support plate body and a film layer arranged on the surface of at least one side of the support plate body, and the film layer comprises at least one of a metal film layer and a polymer film layer; the printing carrier plate further comprises a groove array, and the groove array penetrates through the film layer and extends to the carrier plate body in the thickness direction of the printing carrier plate. According to the utility model, the quality of groove laser etching can be improved.

This invention provides a method, apparatus, device, and medium for landing unmanned aerial vehicles (UAVs). The method includes: determining whether the UAV meets the necessary set of conditions for landing in the hangar based on the hangar health status vector and the UAV's own self-sensing status vector, and generating landing control commands for the UAV, including landing commands at the original hangar or at an alternate landing site; controlling the UAV to fly to the original hangar and land according to the landing procedure based on the original hangar landing command and a preset landing procedure at the original hangar; and generating flight path information for the UAV from its current position to the alternate landing site based on the alternate landing site landing command and alternate landing site information, so that the UAV can fly to the alternate landing site and land according to the flight path information. This solution can significantly improve the safety of UAV return landing and reduce the risk of crash and damage when the return point is unavailable.
