Fabrication of Hybrid Organic Photovoltaic Devices Using Electrostatic Spray Method

الملخص EN

Hybrid organic photovoltaic devices (OPVDs) are fabricated using the electrostatic spray (e-spray) method and their optical and electrical properties are investigated.

E-spray is used to deposit a hybrid film (P3HT: PCBM/nanodiamond) with morphology and optical characteristics onto OPVDs.

The root-mean-square roughness and optical absorption increase with increasing nanodiamond content.

The performance of e-spray is comparable to that of the spin-coating method under uniform conditions.

The device takes advantage of the high current density, power conversion efficiency, and low cost.

Nanodiamond improves the short-circuit current density and power conversion efficiency.

The best performance was obtained with 1.5 wt% nanodiamond content, with a current density of 7.28 mA/cm2 and a power conversion efficiency of 2.25%.
