Abstract: A non-vacuum processing method for preparing polymer-based ZrO 2 /TiO 2 multilayer structure antireflection coating (ARC) films for crystalline silicon solar cells by spin coating is introduced. Initially, ZrO 2 , TiO 2 and surface deactivated-TiO 2 (SD-TiO 2 ) based films were examined separately and the effect of photocatalytic properties of TiO 2 film on the reflectivity on silicon surface was investigated. Degradation of the reflectance performance with increasing reflectivity of up to 2% in the ultraviolet region was confirmed. No significant change of the reflectance was observed when utilizing SD-TiO 2 and ZrO 2 films. Average reflectance (between 300 nm–1100 nm) of the silicon surface coated with optimized polymer-based ZrO 2 single or ZrO 2 /SD-TiO 2 multilayer composite films was decreased down to 6.5% and 5.5%, respectively. Improvement of photocurrent density ( Jsc ) and conversion efficiency (?) of fabricated silicon solar cells owing to the ZrO 2 /SD-TiO 2 multilayer ARC could be confirmed. The photovoltaic properties of Jsc , the open-circuit photo voltage ( V OC ), the fill factor ( FF ), and the ? were 31.42 mA cm ?2 , 575 mV, 71.5% and 12.91%. Efficiency of the solar cells was improved by the ZrO 2 -polymer/SD-TiO 2 polymer ARC composite layer by a factor of 0.8% with an increase of Jsc (2.07 mA cm ?2 ) compared to those of fabricated without the ARC.
