1. INTRODUCTION Since Tang and Van Slyke invented the first efficient organic light-
emitting diode (OLED) based on small molecules in 1987, and Friend et al. in 1990, based …

We begin with a general description of the chemical, physical, and electrical properties of
organic semiconductors, OSCs, a class of materials that includes molecular semiconductors …

A graphene–semiconductor heterojunction is very attractive for realizing highly sensitive
phototransistors due to the strong absorption of the semiconductor layer and the fast charge …

This paper reviews the properties and phases of fullerenes and their derivatives and
compounds under high pressures. For obvious reasons most of the paper deals with C60 …

Organic solar cells are thought to suffer from poor thermal stability of the active layer
nanostructure, a common belief that is based on the extensive work that has been carried …

This review concerns the concept of multi-excitation entropy (MEE) and its consequences.
When a fluctuation involving a large number of excitations occurs, for example, when a large …

Carbon-based spin valves, composed of a C60 layer sandwiched between two magnetic
materials show room temperature spin transport for a fullerene thickness up to 30 nm. This …

A stable small-molecule organic photovoltaic device with structure of ITO⧹ donor⧹
acceptor⧹ buffer⧹ cathode is presented. A thin layer (∼ 60Å) of tris-8-hydroxy-quinolinato …

Organic solar cells (OSCs) are lightweight, have adaptable colors, and can be produced in
low‐cost procedures on transparent and flexible surfaces. This makes them attractive for …

Semi-transparent P3HT: PCBM (poly (3-hexylthiophene):[6, 6]-phenyl C61 butyric acid
methyl ester) solar cells with high conductivity PEDOT: PSS (poly (3, 4 …
