PURPOSE: A photovoltaic power generation apparatus is provided to reduce the areas of through grooves by forming first through grooves corresponding to the separation grooves. CONSTITUTION: Separation grooves (130) are formed in a substrate. A back electrode layer is arranged in the separation groove. A base layer (110) supports a protrusion part (120). A front electrode layer is arranged on a light absorption layer. First through grooves correspond to the separation grooves. [Reference numerals] (AA) Second direction |
