NOVELTY - An ink composition comprises hole transport materials and a fluorosurfactant.    USE - As ink composition for forming the hole transport layer of an inverted photovoltaic device e.g. light emitting diodes (LED), an organic light emitting diodes (OLED), an organic photovoltaic devices (OPV), an electrochromic device, a supercapacitor, a battery, an actuator, or a transistor; and inverted solar cell (claimed).    ADVANTAGE - The composition provides improved wettability. The device demonstrates an increase in power conversion efficiency of at least 20% (preferably at least 50%) compared to a substantially analogous device having a hole transport layer composition which does not include the fluorosurfactant. The method reduces or eliminates the need for pretreatment of active or electrode layers, which involves additional steps and can be deleterious to device performance. The device shows better stability and lifetime; and improved adherence and film uniformity. The device controls properties of hole injection and transport layers such as adhesion, solubility, thermal stability, and electronic energy levels such as highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO), so that the materials can be adapted for different applications and to function with different materials such as light emitting layers, active layers, and electrodes.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a device comprising a substrate (110), at least one cathode, at least one anode (120), at least one active layer (140) disposed between the cathode and anode, and at least one hole transport layer (130), where the hole transport layer (A1) comprises a composition comprising i) at least one hole transport material, and ii) at least one fluorosurfactant;    (2) forming an inverted photovoltaic device involving forming a first electrode on a substrate, forming a hole blocking layer on the first electrode, forming an active layer on the hole blocking layer, forming a hole transport layer (A1) on the active layer, and forming a second electrode on the hole transport layer; and    (3) forming an ink usable for deposition as the hole transport layer of a photovoltaic device involving a) providing a first solvent, b) providing a conjugated polymer, c) providing an organic polymer different from (b), d) providing a fluorosurfactant, e) providing a second solvent, and f) combining in any order (a), (b), (c), (d) and (e) to form an ink composition.
