Electron transport and back reaction in DSC are investigated under different illumination intensities. The modifications of anode, blocking layer and modified TiO 2 films, are performed by electrodeposition. It is found that short-current density J sc and efficiency η of DSC are improved, but different mechanisms are obtained: the optimization of TCO by coating a blocking layer can effectively extend electron lifetime τ n , but it has little influence on electron transport. On the other hand, the optimization of TiO 2 film can enhance electron transport, finally shorten transit time τ d and extend τ n .","claims":[{"public_id":"cl_7b7381f2551c024b1d7a0ccb74d4098a","status":"active","text":"Coating a blocking layer on the TCO extends electron lifetime τ_n but has little influence on electron
