Abstract: A refrigerator that is capable of enabling a user to easily introduce or remove goods into or from the refrigerator is described. Specifically, a refrigerator that is capable of enabling a drawer for receiving goods to be more conveniently used is described. The refrigerator includes a cabinet having a storage compartment with a food introduction port formed in the front thereof, a door hingedly connected to the cabinet for opening and closing the storage compartment, a plurality of drawers disposed in the storage compartment, the drawers being arranged vertically, a moving frame extending vertically so as to correspond to the height at which the drawers are disposed, the moving frame being configured to selectively push the drawers such that the drawers are moved toward the food introduction port, an electric driving unit coupled to the moving frame for moving the moving frame toward the food introduction port, and a controller for controlling the electric driving unit to move the moving frame when it is sensed that the door is open.

Abstract: A solar cell includes a substrate of a first conductive type, a plurality of first electrodes positioned on one surface of the substrate in parallel with one another, and a plurality of back surface field regions which are positioned respectively correspondingly to the plurality of first electrodes, are separated from one another, and are doped with impurities of the first conductive type at a concentration higher than the substrate. Each back surface field region includes discontinuous regions in a longitudinal direction of the first electrodes. An impurity concentration of the discontinuous regions is lower than an impurity concentration of the back surface field region.
