Amorphous silicon thin film solar cells with engineered nanoparticles

This thesis explores the enhancement effects of plasmonic nanoparticles and dielectric SiO2 nanoparticles on the absorbance in amorphous silicon thin films solar cells. The nanoparticle imprinting technique has been developed in the ultrathin solar cell fabrication for the first time. At last, when this nanoparticle imprinting technique is used to imprint the optimized hetero-structured lumpy nanoparticles in solar cells, a 20 nm thick solar cell can achieve a comparative absorption to a 300 nm thick solar
