摘要： An organic dye for a dye-sensitized solar cell (DSSC) comprising at least one electron-acceptor unit and at least one π-conjugated unit is described. Said organic dye is particularly useful in a dye-sensitized photoelectric transformation element which, in its turn, can be used in a dye-sensitized solar cell (DSSC).

摘要： Process for the preparation of a benzohetero-[1,3]diazole compound disubstituted with brominated heteroaryl groups which comprises reacting at least one dihalogenated benzohetero[1,3]diazole compound with at least one brominated heteroaryl compound. Said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used in the synthesis of compounds useful in the construction of solar concentrators (LSCs—“Luminescent Solar Concentrators”). Furthermore, said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used in the synthesis of photoactive polymers useful in the construction of photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), on both rigid or flexible supports. Furthermore, said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used as precursor of monomeric units in the synthesis of semiconductor polymers.

摘要： 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.
