Sb2s3 Grown By Ultrasonic Spray Pyrolysis And Its Application In A Hybrid Solar Cell
BEILSTEIN JOURNAL OF NANOTECHNOLOGY(2016)
摘要
Chemical spray pyrolysis (CSP) is a fast wet-chemical deposition method in which an aerosol is guided by carrier gas onto a hot substrate where the decomposition of the precursor chemicals occurs. The aerosol is produced using an ultrasonic oscillator in a bath of precursor solution and guided by compressed air. The use of the ultrasonic CSP resulted in the growth of homogeneous and well-adhered layers that consist of submicron crystals of single-phase Sb2S3 with a bandgap of 1.6 eV if an abundance of sulfur source is present in the precursor solution (SbCl3/SC(NH2)(2) = 1: 6) sprayed onto the substrate at 250 degrees C in air. Solar cells with glass-ITO-TiO2-Sb2S3-P3HT-Au structure and an active area of 1 cm(2) had an open circuit voltage of 630 mV, short circuit current density of 5 mA/cm(2), a fill factor of 42% and a conversion efficiency of 1.3%. Conversion efficiencies up to 1.9% were obtained from solar cells with smaller areas.
