A vehicular component, such as vehicular roof or vehicular hood or vehicular door or vehicular side-panel or vehicular trunk cover, has a plurality of electrically interconnected flexible solar cells, that are integrally embedded therein. Optionally, the vehicular component has curvatures or has non-planar regions or curved regions; and the integrally embedded flexible solar cells are arranged in a three-dimensional structure that follows or matches the vehicular contour. The embedded flexible solar panels are not directly in touch with the air that surrounds the vehicle; rather, they are infused or embedded within one or more layers of the vehicular component; optionally sandwiched between encapsulant layers; optionally further sandwiched between a topsheet and a backsheet; optionally further sandwiched between two thermoformed layers that are formed of polycarbonate or other thermoformable materials.
