NOVELTY - An inverted polymer photovoltaic cell comprises an anode, an anodic interlayer (buffer layer) (L1) based on (poly(3,4-ethylenedioxythiophene):polystyrene sulfonate), an active layer comprising at least one photoactive organic polymer as an electron donor and at least one electron acceptor organic compound, a cathodic interlayer (buffer layer), a cathode, an anodic interlayer (buffer layer) (L2) comprising at least one heteropolyacid, and optionally at least one amino compound placed between layer (L1) and active layer. USE - Inverted polymer photovoltaic cell i.e. solar cell. ADVANTAGE - The inverted polymer photovoltaic cell has excellent electronic characteristics and optical characteristics such as improved highest occupied molecular orbital level and lowest unoccupied molecular orbital level, molar absorption coefficient, solubility in solvents, and mobility of the electron holes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the inverted polymer photovoltaic cell (or solar cell), which involves forming the cathode by sputtering or by electron beam assisted deposition or by depositing a transparent conductive polymer through spin coating, or gravure printing, flexographic printing, or slot-die coating, depositing grids in the conductive material through evaporation, screen-printing, spray-coating, or flexographic printing, or depositing an ink based on metal nanowires through spin coating, gravure printing, flexographic printing, or slot-die coating, forming the cathodic interlayer by spin coating, gravure printing, flexographic printing, or slot-die coating above the cathode, forming the active layer by spin coating, gravure printing, or slot-die coating above the cathodic interlayer, forming layer (L2) by spin coating, gravure printing, screen-printing, flexographic printing, or slot-die coating above the active layer, forming layer (L1) by spin coating, gravure printing, screen-printing, flexographic printing, or slot-die coating above layer (L2), forming the anode by vacuum evaporation, screen-printing, spray-coating, or flexographic printing above layer (L1), or by deposition of the transparent conductive polymer through spin coating, gravure printing, flexographic printing, or slot-die coating, depositing grids in the conductive material through evaporation, screen-printing, spray-coating, or flexographic printing above layer (L1), or depositing an ink based on metal nanowires through spin coating, gravure printing, flexographic printing, or slot-die coating above layer (L1).
