Abstract

A solution processed polymer tandem cell has been fabricated by using the organic layer coated crystalline $TiO_2$ nanoparticle inter layer. The highly dispersive OL-$TiO_2$ has several advantages in terms of excellent film forming property, crystallinity, optical transparency, and well defined chemical composition. The surface morphology of the $TiO_2$ thin film was found to play a crucial role in the performance of the polymer tandem cell. The stability of the tandem cell, utilizing dense $TiO_2$ nanoparticles inter layer, was superior to the stability of the single junction cell.
