There is a polymeric photovoltaic cell (or solar cell) with inverted structure having an anode; an anodic buffer layer; an active layer having at least one photoactive organic polymer as electron-donor and at least one electron-accepting organic compound; a cathodic buffer layer; and a cathode. The at least one photoactive organic polymer is selected from conjugated polymers comprising an anthraditiophenic derivative having a general formula (I): The polymeric photovoltaic cell (or solar cell) with inverted structure shows good values of power conversion efficiency (PCE) (η) and can be advantageously used in the construction of photovoltaic modules (or solar modules), either on a rigid support or on a flexible support.
