• 88 mm2 cell, independent of the initial JSC value. The linear decrease of JSC during aging in light or dark conditions correlates with the general trend in organic PV [9], meaning the stability of Sb2S3 hybrid solar cell hinges on the stability of the chosen HTM. The FF increased slightly in the 88

• integrating semitransparent thin films of Sb2S3 with optimized thickness of 100 nm in the planar ITO/TiO2/Sb2S3/P3HT/Au hybrid solar cell, a PCE of 5.5% and an AVT of 26% in ITO/TiO2/Sb2S3 were achieved. The PCE and AVT combinations obtained in this study are similar to those reported for other

• hole conductor coupled with inorganic materials leads to the notation of a hybrid solar cell [13]. Based on dense TiO2 covered by mesoporous TiO2 and then impregnated with a light harvester, the resulting solar cells are commonly referred to as mesoscopic solar cells [14] the first of which, based on

• ]. In this work, we report the first results on growing Sb2S3 by ultrasonic chemical spray pyrolysis (ultrasonic CSP), and on the application of ultrasonic CSP grown Sb2S3 as an absorber in a hybrid solar cell. The aim of this work is to obtain a single-phase Sb2S3 absorber by ultrasonic CSP, and to

• photovoltaics [5][6]. To this day, numerous inorganic semiconductors such as ZnO, TiO2, CdSe, CdS, PbSe and PbS have been studied. Particular focus has been put on the investigation of selenides or sulfides in conjunction with organic polymers (MEH-PPV, P3HT) for hybrid solar cell applications [6][7]. However

In order to achieve an efficient hybrid solar cell performance, it is imperative to control the morphology of both organic and inorganic components without any phase separation at macroscopic scale. The implementation of such a control of the
