| Popis: | 8th World Conference on Photovoltaic Energy Conversion; 313-315 The aim of this work is the study of the degradation of two different PSCs. A PSC with undoped SnO2 ETL was compared to a PSC with ETL made of G-SnO2. Degradation was monitored by performing both impedance spectroscopy and dark I-V measurements. Experimental data were collected just immediately after fabrication and after one week. It was observed that the degradation of the solar cells affects both the AC behavior of the devices, modifying associated Nyquist plots, and the DC behavior, observable from dark current-voltage curves. From the Nyquist plots a quantitative analysis was performed by comparing the parameters of a proper equivalent circuit model. Results were coherent with those achieved with DC analysis, thus providing that the arising from these two techniques allows to gain a deeper knowledge of the degradation phenomena. |
