Barium Oxide as an Intermediate Layer for Polymer Tandem Solar Cell

Polymer solar cells (PSCs), a member of organic solar cell family, have attracted increasing research interest. PSCs possess significant advantages over their inorganic solar cell counter parts: mechanical flexibility, light weight, low expense, and the potential to achieve roll-to-roll large-scale production. Tandem solar cells, in which two solar cells are linked to take more use of the solar energy, were fabricated with each solution processed layer using Bulk Heterojunction (BHJ) materials comprising semiconducting polymers and fullerene derivatives. For years, tremendous efforts have been put in seeking for an efficient intermediate layer to successfully connect two sub-cells together in the tandem structure. Even though many kinds of intermediate layers such as ZnO/MoO3 etc. have been explored, most of them suffer from the low conductivity or complicated manipulation disadvantages. Barium oxide (BaO) is both high conductive and wide bandgap n-type semiconductor. We successfully fabricated the polymer tandem solar cell using all thermal vacuum deposition fashion with BaO/Ag/MoO3 as an intermediate layer. VOC of the tandem structure is the sum of the component cells demonstrating our proposed intermediated layer can efficiently connect sub-cells with no potential/energy loss.
