The thinner thickness of compressed thin film is helpful to the reduction of electron transfer way, and reduces resistance and increases adsorbability toward dye relatively. However, the efficiency of zinc oxide thin film after compression becomes worse due to disarrangement of its structure, hole reduction on thin film structure, and disordered pileup format of reuniting dye molecules. Above reasons lead to the deactivation of electron-injection efficiency and the loss of current, thus compressed ZnO thin film reduces the cell efficiency.
