Molecular solar cells. Part 1: Devices based on easily doped insulators

The fabrication of molecular (organic and metallo-organic) solar cells necessitates to at least partly master fundamental solid state physics of molecular materials as well as the chemistry of dyes and conjugated compounds. This multidisciplinary approach allows to envisage practical applications. This publication is divided in two parts depending on the type of molecular materials used: easily doped insulators or intrinsic molecular semiconductors. It is important to distinguish between these two types of materials since the electrical properties of easily doped insulators are as dependent of the concentration and type of the impurities present as of the chemical nature of the molecular compound itself.
