Light manipulation using organic semiconducting materials for enhanced photosynthesis

Light Manipulation in Organic Photovoltaics

Organic photovoltaics (OPVs) hold great promise for next-generation photovoltaics in renewable energy because of the potential to realize low-cost mass production via large-area roll-to-roll printing technologies on flexible substrates. To achieve high-efficiency OPVs, one key issue is to overcome the insufficient photon absorption in organic photoactive layers, since their low carrier mobility...

Amplified Spontaneous Emission Properties of Semiconducting Organic Materials

This paper aims to review the recent advances achieved in the field of organic solid-state lasers with respect to the usage of semiconducting organic molecules and oligomers in the form of thin films as active laser media. We mainly focus on the work performed in the last few years by our research group. The amplified spontaneous emission (ASE) properties, by optical pump, of various types of m...

Phosphorescent materials for application to organic light emitting devices*

Organic phosphors have demanded the attention of the organic electroluminescence community because they enable ef®ciencies quadruple that of ̄uorescent materials. In this work, we review the categories of organic phosphors: lanthanide complexes, organic phosphors and metal-organic complexes. The characteristics necessary for ef®cient phosphorescence are considered and conclusions are drawn as t...
