In this work, we propose poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) material to form a hybrid heterojunction with amorphous silicon-based materials for high charge carrier collection at the frontal interface of solar cells. The nanostructural characteristics of PEDOT:PSS layers were modified using post-treatment techniques via isopropyl alcohol (IPA). Atomic force microscopy (AFM), Fourier-transform infrared (FTIR), and Raman spectroscopy demonstrated conformational changes and nanostructural reorganization in the surface of the polymer in order to tailor hybrid interface to be used in the heterojunctions of inorganic solar cells.

- Thin-film hybrid organic-inorganic photovoltaic structures were developed using hydrogenated silicon, PEDOT:PSS polymer, and Al-doped ZnO films on flexible substrates.
- The compatibility of these materials and their deposition techniques was validated through morphological and electronic characteristic measurements.
- The best performance was achieved with structures on polyethylene naphthalate (PEN) substrates, showing a short circuit current density of 9.79 mA/cm² and a power conversion efficiency (PCE) of 1.3%.
