Abstract: A method for diagnosing an internal loss mechanism of a solar cell is provided. The solar cell includes an anode and a cathode. An electron transport layer, an active layer and a hole transport layer are arranged in sequence from top to bottom between the cathode and the anode. The solar cell is modeled through a solar cell multi-physics simulation platform. Current density-voltage (JV) curves respectively of type A, type B, type C and type D are simulated by regulating a bulk defect and a surface defect of the active layer and a voltage scan rate. The solar cell is subjected to forward voltage scan and reverse voltage scan to obtain forward and reverse JV curves. According to the forward and reverse JV curves, whether the JV curve type of the solar cell is the type A, the type B, the type C or the type D is determined.
