The utility model discloses a homojunction perovskite thin film solar cell, a serial communication port, solar cell's structure does from supreme down in proper order: transparent conductive coating 1, P type perovskite thin film 2, N type perovskite thin film 3, anti -reflecting layer 4, metal electrode 5. The utility model has the advantages of: (1 )Utilize homojunction perovskite thin film to constitute the good smooth absorption property of solar cell full play perovskite, avoided the carrier compound because the material crystalline grain mismatches in transport process, improved carriermobility, (2 )Utilizing the hydrophobic anti -reflection effect of anti -reflecting layer, increasing on the one hand the battery to the absorption of sunlight, physical contact between effective separation metal electrode of on the other hand and the perovskite thin film prevents compound energy that causes of interface charge and electric charge loss to water oxygen in effective separation air gets into and leads to the
