Diurnal efficiency degradation and overnight recovery was observed over the outdoor testing period. In addition, the performance recovery of the mini-modules was investigated after their removal from the field to detect differences in the reversible process mechanisms between the different module compositions. Light current-voltage (IV) scans, Resonance Raman spectroscopy techniques and spatially-resolved Electroluminescence (EL) measurements were utilized for this purpose.enPhotovoltaic systemsDegradationCurrent measurementRaman scatteringPerovskitesElectroluminescenceTestingconference paper
