Embodiments of the disclosure include an electronic device comprising a first electrode, a second electrode, a first layer disposed between the first electrode and the second electrode, the first layer comprising a metal-halide perovskite material, and an adhesive layer disposed between the first layer and the second electrode, wherein the adhesive layer comprises an organic material. Embodiments of the disclosure generally relate to photovoltaic module products, such as photovoltaic cells, photovoltaic devices and photovoltaic modules that include an absorber layer that comprise a perovskite material. Embodiments of the disclosure include an improved perovskite solar cell architecture that includes one or more buffer layers disposed within the multilayer stack of thin films used to form a solar cell that can exhibit high solar cell performance, and provide stronger adhesion between adjacent layers and/or cohesion within a layer within the multilayer stack used to form the solar cell device.
