Mott-Schottky Analysis of the P3HT:ZnScubic and P3HT:ZnShexa Bulk Heterojunction Solar Cells

摘要

Bulk heterojunction solar cells of sphalerite and wurtzite ZnS incorporated P3HT were fabricated and their Mott-Schottky analysis was performed to find the conduction mechanism of the devices. The analysis shows the formation of a Schottky junction and band unpinning at the P3HT:ZnS-Al contact and it confirms the hole conductivity in the active material.
