Lipophilic cosmetic compositions containing pelargonic acid esters

Aqueous cosmetic compositions comprising at least 20% by weight of an aqueous component and a lipophilic component characterized in that the lipophilic component comprises at least one ester selected from neopentylglycol dipelargonate, glycerol tripelargonate, pentaerythritol tetrapelargonate or mixtures thereof.

Aqueous cosmetic compositions containing pelargonic acid esters

Polymeric photovoltaic cell (or solar cell) with an inverted structure comprising: an anode; a first anode buffer layer; an active layer comprising at least one photoactive organic polymer as the electron donor and at least one organic electron acceptor compound; a cathode buffer layer; a cathode; wherein between said first anode buffer layer and said active layer a second anode buffer layer is placed comprising a hole transporting material, said hole transporting material being 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 at least an equivalent amount of a salt or a 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, preferably alcohols. Said polymer photovoltaic cell (or solar cell) with an inverted structure displays high photoelectric conversion efficiency values (&#x3b7;), i.e. a photoelectric conversion efficiency (&#x3b7;) greater than or equal to 4.5%, and good open circuit voltage (Voc), short-circuit current density (Jsc) and fill factor (FF) values. Furthermore, said polymer photovoltaic cell (or solar cell) with an inverted structure is able to maintain said values over time, in particular, in terms of photoelectric conversion efficiency (&#x3b7;).
