NOVELTY - An article comprises a first electrode, a second electrode, a photoactive layer between the first electrode and the second electrode, and a hole carrier layer between the first electrode and the photoactive layer, where the hole carrier layer comprises an oxidizing agent and a hole carrier polymer.    USE - As an article including photovoltaic cell (claimed) used to transfer energy in form of light into electricity.    ADVANTAGE - The photovoltaic cell has high conversion efficiency and improved life span.    DETAILED DESCRIPTION - An article comprises a first electrode, a second electrode, a photoactive layer between the first electrode and the second electrode, and a hole carrier layer between the first electrode and the photoactive layer, where the hole carrier layer comprises an oxidizing agent and a hole carrier polymer, where the oxidizing agent is selected from compound of formula (I), NOPF6 (II) and compound of formula (III) and their blends.    R1-R4=H, fluoro, chloro, bromo, iodo, NO2, COOH, or CN;    X1 and X2=O, S, Se, or NR9;    R5-R8=H, fluoro, chloro, bromo, iodo, NO2, COOH, CN, or groups of formulae (i)-(iii) or their blends;    R9=phenyl (optionally substituted with 1-10C alkyl) or 1-10C alkyl;    R10=H or F (preferably F);    n and m=0-10 (preferably 0-5, especially 1 or 2).    Where the asterisk represents the bonds to other monomeric units of the polymer. Provided that:    (1) at least two of R1-R8 are different from H;    (2) one of R5-R8 is -Sp-Pol selected from compound (i)-(iii); and    (3) at least two of R5-R8 are selected from H, F, Cl, NO2, COOH or CN.    An INDEPENDENT CLAIM is included for manufacturing the article, either involving (a1) mixing the hole carrier polymer and the oxidizing agent and dissolving them together in a solvent, or dissolving the hole carrier polymer in a first solvent and the oxidizing agent in a second solvent and then mixing the two solutions, and (b1) subsequently coating the resulting solution from step (a1) over a layer underneath; or (a2) dissolving the hole carrier polymer in a first solvent to obtain a first solution, (b2) coating the first solution over a layer underneath, (c2) drying the resulting layer of hole carrier polymer, (d2) dissolving the oxidizing agent in a second solvent to obtain a second solution, and (e2) coating the second solution over the layer of hole carrier polymer obtained in step (c2), where the first and second solvent may be the same or different, and where the article is a photovoltaic cell.
