Vacuum deposited organic and composite charge transport layers for photovoltaic devices

Abstract:

This thesis studies the mechanisms by which charge transport layers influence photovoltaic device performance.

Organic hole transport layers of pentacene (Ptn) are employed in quantum dot (QD) photovoltaic devices to improve performance. Device operation mechanisms are studied through current-voltage (IV) testing, complemented by Kelvin Probe measurements of QD and Ptn layer Fermi levels. The results reveal that space-charge effects initially cause s-shaped IV curves and identify Pt...
