PHOTOVOLTAIC POWER GENERATION APPARATUS HAVING IMPROVED PHOTOELECTRIC CONVERSION EFFICIENCY AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A photovoltaic power generation apparatus and a manufacturing method thereof are provided to prevent recombination of electrons by controlling bandgap energy of an optical absorption layer into a harmonic type.;CONSTITUTION: A rear electrode layer is arranged on a substrate. An optical absorption layer is arranged on the rear electrode layer. A front electrode layer is arranged on the optical absorption layer. The rear electrode layer includes a first region(311), a second region(312), a third region(313) and a fourth region(314). The optical absorption layer includes a fifth region(315), a sixth region(316), a seventh region(317) and an eighth region(318).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Optical absorption level; (BB) Buffer level
