Abstract
- In this work, we have fabricated hybrid heterojunction solar cells with structure ITO/ZnO/P3HT:PCBM:CTSe NCs (optimized weight percentage 10 wt%)/MoO<subscript>3</subscript>/Ag (device SM10). A thin layer of molybdenum oxide MoO<subscript>3</subscript> prepared by peroxomolybdic acid organosol as the precursor was used as hole transport layers (HTLs). The performance of the device was compared with ITO/ZnO/P3HT:PCBM:CTSe NCs/Ag(device S10). The important parameters such as global charge carrier mobility (µ), effective charge carriers lifetime (τ<subscript>n</subscript>) and charge diffusion time (τ<subscript>d</subscript>) have been extracted from electrochemical impedance spectroscopy (EIS) performed at the bias of 0.1 V in the dark. The Nyquist plot obtained from EIS has demonstrated effective carriers lifetime, global mobility and charge diffusion time for a device SM10 as 6.46 ms, 12.6 × 10<superscript>−4</superscript> cm<superscript>2</superscript> V<superscript>−1</superscript> S<superscript>−1</superscript> and 5.2 µs and for device S10 as 5.65 ms, 9.58 × 10<superscript>−4</superscript> cm<superscript>2</superscript> V<superscript>−1</superscript> S<superscript>−1</superscript> and 6.8 µs, respectively.
