A solar cell module includes a substrate, a lower electrode layer, a semiconductor layer and an upper electrode layer for an embodiment. The lower electrode layer may include a plurality of area-separating grooves separating the substrate into an active area and a peripheral area surrounding the active area, and a plurality of first cell-separating grooves formed in the active area. The semiconductor layer is formed on the lower electrode layer. The semiconductor layer includes a plurality of second cell-separating grooves that are spaced apart from the first cell-separating grooves. The upper electrode layer is formed on the semiconductor layer. The upper electrode layer includes a plurality of third cell-separating grooves that are spaced apart from the second separating grooves.

Solar cell module and method of manufacturing the same

A method of controlling an Automatic Guided Vehicle (AGV) system having a plurality of AGVs includes setting a moving path with task times of all the AGVs taken into account, and controlling the AGVs according to the set moving path. The setting the moving path includes calculating respective costs required for the AGVs to perform a plurality of tasks and calculating a number of cases occurring by allocation of each of the tasks to the AGVs. The setting the moving path also includes calculating respective total costs required for the AGVs to perform a corresponding task or corresponding tasks for all of the cases, determining a smallest and largest value out of the respective total costs for each of the cases, and setting the moving path of the AGVs according to the case having the smallest value.
