Organic photovoltaic solar cells potentially offer light weight, mechanical flexibility, and low cost roll-to-roll fabrication – especially when manufactured by vacuum-free processes in ambient air with polymeric electrodes. Transfer lamination is a dry process that avoids issues from wetting and film damage caused by solvents used in spin coating or other additive wet-deposition methods. Research funded as part of CISSEM at Georgia Tech (Kippelen) has demonstrated the first semitransparent, all-plastic solar cells prepared in ambient air using sequential dry film-transfer lamination of the photoactive layer and a high-conductivity polymeric top electrode. Current–voltage characteristics of our all-plastic cells were successfully measured as a function of light irradiance over five orders of magnitude; from the dark to the one-sun standard solar spectrum. By using dry film-transfer lamination we realize a very low density of defects for the active layer – much superior to a spin-coated active layer. Consequently, these all-plastic solar cells have a high photovoltaic dynamic range. They produce a photovoltaic response even when the one-sun incident irradiance is attenuated by as much as one million. The extremely low dark current under reverse bias shows the potential of dry film-transfer lamination to produce quality, well-interfaced, low-defect active layers, while easing solvent selection for organic electronics. Our results demonstrate the prospects of organic solar cells for light-weight, portable, stand-by power generation under room light, and even weaker, illumination.
