The utility model relates to a photonic crystal light tripping structure for thin -film solar cell, characterized by: mainly constitute by sunken photosphere of two -dimensional photonic crystal and one -dimensional photonic crystal reflection configuration, wherein: two -dimensional photonic crystal falls into the photosphere and constitutes at the upper and lower side's of thin -film solar cell absorbed layer two -dimensional photonic crystal by setting up respectively, and two -layer two -dimensional photonic crystal's structural parameters is the same. The utility model discloses a double -deck two -dimensional photonic crystal light tripping structure make full use of the optical characteristic of two -dimensional photonic crystal decline angle scattering incident light, upper and lower two -layer two -dimensional photonic crystal with the incident light with the decline corner reflection to the battery absorbed layer inside, great extension the transmission route of photon, and simultaneously, the total
