Title: HOLE TRANSPORTING MATERIAL AND PHOTOVOLTAIC DEVICE THAT USES IT
Abstract:
Hole transporting material obtained through a process comprising: reacting at least one heteropoly acid containing at least one transition metal belonging to group 5 or 6 of the Periodic Table of the Elements; with an equivalent amount of at least one salt or one complex of a transition metal belonging to group 5 or 6 of the Periodic Table of the Elements with an organic anion, or with an organic ligand; in the presence of at least one organic solvent selected from alcohols, ketones, esters. Said hole transporting material can be advantageously used in the construction of photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), either on a rigid support, or on a flexible support. Furthermore, said hole transporting material can be advantageously used in the construction of Organic Light Emitting Diodes (OLEDs), or of Organic Field Effect Transistors (OFETs). In particular, said hole transporting material can be advantageously used in the construction of a polymer photovoltaic cell (or solar cell) with an inverted structure.
