Abstract

Abstract: Inverted organic solar cell (IOSC) devices with different volume ratios of In2 S3 nanoparticles have been studied under local spectral irradiances in Malaysia with respect to that of AM1.5G. The J-V curves of encapsulated IOSC devices were measured outdoor using an Ivium Potentiostat and local spectral irradiances were acquired using an AVANTES spectrometer concurrently. All of the IOSC devices experienced significant improvement in power conversion efficiency (PCE) under the both local sunny and cloudy conditions with respect to the AM 1.5G, by 22–35% and 31–65%, respectively. From spectral analysis, the area under the graph of spectral irradiance in UV–visible region is significantly higher compared to infrared region for both local sunny and cloudy conditions, by 44.6% and 55.9%, respectively, while it is only recorded as 12.9% for AM 1.5G. Last but not the least, we have successfully verified the numerical analysis to predict device performance by comparing the simulated and measured PCE values for different irradiance intensities whereby the prediction of PCE is better under sunny condition with a deviation of 3.4–10.8% compared to cloudy conditions, with deviation of 28.9–30.5%. Graphical abstract: Image 10425 Highlights: Local solar spectrums matched well with light absorption band of 0.6 INPs-IOSC. UV–Vis region for cloudy, sunny and AM 1.5G illuminations are 56%, 45%, 13%. PCE improves under local sunny relative to AM1.5G condition with 22–35%. PCE improves under local cloudy relative to AM1.5G condition are 31–65%. Prediction of PCE is better under sunny condition as compared to cloudy condition.
