Cholesteric aggregation at the quinoidal-to-diradical border enabled stable n-doped conductor

Abstract

Semiconductor materials constitute the heart of solar cells since they are responsible of the photovoltaic effect. For this reason, the search of new materials to improve the efficiency and stability of these devices is on the focus of the organic electronics. These semiconductors are typically formed by p-doped materials. Despite the relative high abundance of molecules suitable for photovoltaic purposes, that is, able of absorbing light and allowing the transport of the new created charges through them, n-doped organic semiconductors are not plentiful due to their well-known ambient instability.
