Abstract We investigate the re-exciting process of a soliton, a polaron and a bipolaron in conjugated polymers. For a soliton case, the processes S0+ hυ=>S±+Pμ and S±+ hυ=>S0+P± will take place, where S0, S± and P±express a neutral soliton, charged solitons and charged polarons,respectively. For a polaron case, the processes P±+ hυ=> P^μ + BP±2 will occur, where BP±2 expresses a charged bipolaron with two electronic units. For a bipolaron case, the processes BP±2+ hυ=>P±+ P±and BP±2+hυ=> BP±2 +E0 are obtained.
