Abstract EN
Monodisperse CdS spheres of size of 40 to 140 nm were obtained by microwave heating from basic solutions.
It is observed that larger CdS spheres were formed at lower solution pH (8.4–8.8) and smaller ones at higher solution pH (10.8–11.3).
The color of CdS products changed with solution pH and reaction temperature; those synthesized at lower pH and temperature were of green-yellow color, whereas those formed at higher pH and temperature were of orange-yellow color.
A good photovoltage was observed in CdS:poly(3-hexylthiophene) solar cells with spherical CdS particles.
This is due to the good dispersion of CdS nanoparticles in P3HT solution that led to a large interface area between the organic and inorganic semiconductors.
Higher photocurrent density was obtained in green-yellow CdS particles of lower defect density.
The efficient microwave chemistry accelerated the hydrolysis of thiourea in pH lower than 9 and produced monodisperse spherical CdS nanoparticles suitable for solar cell applications.
