The preparation of flexible polymer solar cells on plastic substrates demands the development of suitable processing conditions. Here we want to compare plastic solar cells prepared by spin coating and by doctor blading. Both, solar cells prepared by only one film formation technique, but also mixed approaches for the processing of the individual hole conducting (PEDOT:PSS) and photoactive (P3HT:PCBM) layers have been tested. After a comprehensive optimization of the blading parameters, the solar cells prepared by this technique achieve very comparable performance than those prepared by traditional spin coating. Further obstacles in the processing of flexible substrates in view of the brittle ITO-layer and thermal stability are discussed.
