Herein, the open-circuit voltage (V-oc) loss in both polymer solar cells and perovskite solar cells is quantitatively analyzed:by measuring the temperature dependence of Voc to discuss the difference in the primary loss mechanism of V-oc between them..As a result, the photon energy loss for polymer solar cells is in the range of about 0.7-1.4 eV, which is ascribed to temperature-independent and-dependent loss mechanisms, while that for perovskite solar cells is as small as about 0.5 eV, which is ascribed to a temperature-dependent loss mechanism. This difference is attributed to the different charge generation and recombination mechanisms between the two devices. The potential strategies for the improvement of Voc in both solar cells are further discussed on the basis of the experimental data.
