The application of Acetonitrile (ACN) on Polymer Solar Cells (PSCs) was investigated in this paper. The conductivity of PEDOT: PS S was significantly enhanced compared with that of untreated samples. The PEDOT: PSS was mixed with freshly prepared co solvents of ACN and De Ionized water . Meanwhile, the Power Conversion Efficiency (PCE) of PSCs was improved by a freshly prepared co sol vent treatment. The PCE of co solvent treated devices achieved 1.27% while the untreated one was only 0.3%. However, expired co solvents were found to be negative to PSCs because of ACN hydrolysis. The PCE of PSCs based on hydrolyzed co solvents was lower than 0.01%. It was found that the H and NH 4 ions generated from ACN aggregates the PEDOT: PSS and roughs the surface of PEDOT: PSS thin films. Meanwhile , Indium ion s was dissolved and transported to the PEODT: PSS surface by the acetic acid could be anot her possibility of the performance decrease . Although the conductivity dramatically increased to 230S cm 1 the series resistance simultaneously increased over 1.5×103 Ω·cm2, leads to a great loss of current output. Because of that, charges could not be transport ed to the electrodes since they are recombined at the PEDOT: PSS surface..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
