An electronic glue-based lamination process combined with interface modification is presented as a one-step process for semitransparent polymer solar cell fabrication. The device is metal-free, semitransparent, flexible, self-encapsulated, and highly efficient, with a maximum external quantum efficiency of 70 % and a power efficiency of 3 % under AM 1.5 global 1 sun solar illumination conditions. This approach represents a critical step towards the ultimate goal of low-cost polymer solar cells.
