Abstract

An effective approach was presented to enhance photoelectric conversion efficiency of Cu(In,Ga)Se₂ (CIGS) solar cells by using modified SiO₂ antireflection coatings (ARCs) to harvest more incident sunlight. Polyethylene glycol (PEG) and polyvinyl pyrrolidone (PVP) used as additives were introduced into silica sols to prepare SiO₂-PEG and SiO₂-PVP coatings in the sol-gel dip-coating process, respectively. The different effects of PEG and PVP additives on SiO₂ coatings were analyzed and the antireflection performance of SiO₂-PEG and SiO₂-PVP coatings was investigated. The transmittance over 97% ranging from 450nm to 700nm with a maximum transmittance over 99.40% at about 550nm was achieved for both SiO₂-PEG2000A and SiO₂-PVP0.5 coatings. The relative efficiencies of CIGS solar cells coated with SiO₂-PEG2000A and SiO₂-PVP0.5 ARCs were increased by 7.27% and 8.33%, respectively. The modified SiO₂ ARCs possessed the advantages of the low manufacturing cost, good adhesion, superior antireflective performance and the feasible method for large area fabrication.
