Simultaneous enhancement in open circuit voltage and short circuit current of hybrid organic-inorganic photovoltaics by inorganic interfacial modification
Here, we investigate the model poly(3-hexathiophene)/ZnO system and show that by introducing a caesium carbonate interlayer, a simultaneous increase in all photovoltaic parameters can be achieved.We kindly acknowledge Prof. Uwe Bunz and Prof. Annemarie Pucci for access to device fabrication facilities and AFM measurements, respectively.
