In this review, we focus on the field of organic photovoltaic cells based on small molecular
weight materials. In particular, we discuss the physical processes that lead to photocurrent …

After efficiency, lifetime is the second most important parameter for organic devices.
Interfaces play a major role in that lifetime. This article reviews the current state of the art with …

Due to their low production costs, small weight, printability, solution processing, and the
possibility of using flexible substrates, organic solar cells (OSCs) exhibit strong potential to …

The effect of bathocuproine (BCP) on the optical and electrical properties of organic planar
heterojunction photovoltaic cells is quantified by current–voltage characterization under 1 …

We report the synthesis, structural identification, and electrical properties of the first one-
dimensional (1-D) nanomaterials of a semiconducting higher manganese silicide (MnSi2− x) …

The interface formed between fullerene (C60) and cathode is a potential limiting factor to the
performance of organic photovoltaic (OPV) cells based on copper phthalocyanine …

This paper introduces the fundamental physical characteristics of organic photovoltaic (OPV)
devices. Photoelectric conversion efficiency is crucial to the evaluation of quality in OPV …

We report the synthesis, structural characterization, and magnetotransport of single-
