In the present study, a new technology that coupled constructed wetland (CW) with microbial fuel cell (MFC) (CW-MFC) was developed to convert solar energy into electricity on the principles of photosynthetic MFC by utilizing root exudates of Ipomoea aquatica as part of fuel. he maximum power density of 12.42 mW m鈭? produced from the CW-MFC planted with Ipomoea aquatica was 142% higher than that of 5.13 mW m鈭? obtained from the unplanted CW-MFC. he maximum power output for the planted CW-MFC could be divided into two parts: the maximum power yield from COD in the water body was 66.05 KJ Kg鈭? COD , and 肀 肀 the maximum power transformation from plant photosynthesis was 2.31 GJ ha鈭? year鈭? . he average COD removal eiciencies were 92.1% and 94.8% in the unplanted CW-MFC and
