Recently, scientists have been interested in developing advanced techniques for technological applications using sustainable biochar (BC) Wooden Car materials.In this study, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate, PEDOT/PSS, was doped with 5 wt.% and 10 wt.

% of Activated biochar (A-BC) obtained from Chlorophyta (green Algae) using a microwave combustion process.XRD, FTIR, TGA, BET, and SEM were used to analyze the structural properties of PEDOT/PSS@BC.The XRD results demonstrate that A-BC impacts the amorphous nature of PEDOT/PSS, causing the doped composite to have a higher crystalline structure.

While measuring dark current density-voltage, it was found that PEDOT/PSS@BC/n-Si showed better-rectifying characteristics compared to pristine PEDOT/PSS/n-Si, with a higher rectification ratio.When A-BC was used, the power conversion efficiency (PCE) was 13.02%, with a short circuit current density (Jsc) of 34.

37 mA/cm2, open-circuit voltage (Voc) of 0.65 V, and fill factor (FF) of 58%.These findings demonstrated that using A-BC improved the characteristics of PEDOT/PSS/n-Si devices, and the increase in performance was helmets affected by the concentration of A-BC.

A-BC can act as an efficient electron acceptor, facilitating charge transfer and reducing recombination losses.
