The invention relates to an integrated solar battery based on a perovskite solar battery and a bulk heterojunction solar battery and a preparation method thereof. The integrated solar battery comprises a transparent electrode, a hole transport layer, a perovskite light absorbing layer, an organic substance blending layer, a random hole block layer and a metal electrode in sequence from the bottom to top. Through preparing the perovskite solar battery and the bulk heterojunction solar battery into the integrated battery, the integrated solar battery based on the perovskite solar battery and the bulk heterojunction solar battery overcomes the disadvantages of narrow light absorbing range of the perovskite solar battery and weak visible light region absorption of the narrow-gap bulk heterojunction solar battery, improves the sunlight use range and improves the energy conversion efficiency. The integrated battery has the similar features to a parallel battery, the conversion efficiency is capable of breaking through the theoretical boundary of the energy conversion efficiency of the single-junction solar battery, and the application prospect is good. |
