organic photovoltaic devices

In response to the current challenges of organic photonics and the demand for organic photodetectors (OPDs) with a broadened spectral range and enhanced sensitivity, this work proposes hybrid non-fullerene systems that combine nickel(II) phthalocyanine (NiPc) metal complexes with boron–dipyrromethene (BODIPY)-based dyes. In this study, a heterostructure based on NiPc and a newly synthesised BODIPY derivative sensitiser (bThBODIPY) was developed and comprehensively evaluated.

An experimental perovskite solar cell (PSC) with the structure Au/Spiro-MeOTAD/CH3NH3PbI3/PEDOT:PSS/ITO was fabricated. The measurements of main photovoltaic characteristics were provided. The current-voltage dependences (I-V curves) were measured conducted in the voltage range from -1V to 1V. During the measurements, the corresponding values were calculated of the short-circuit current density(Jsc) and open-circuit voltage(Uoc) were obtained as 1.23 mA/cm² and 0.19 V, respectively. Subsequently, an analytical model corresponding to this structure was formulated.
