Abstract

Effects of the light-collecting solar cell with high polymer reflecting gratings and experimental accomplishment of periodical gratings on the solar cell surface are studied. It mainly discusses the way and advantage to enhance the solar cell efficiency by using holographic interference lithography to produce high polymer reflecting gratings on the solar cell. Based on the easy processing method, the theoretically calculated open-circuit voltage, Voc, can be raised from 2.62 - 3.618 V, and the maximum voltage, Vm, increases from 2.5 - 3.5 V for a standard commercial Si solar cell. From experiment, the power conversion efficiency for the solar cell is also enhanced from 27 - 35.67%, corresponding to the relative increase of efficiency up to 32.1%. The theoretical analyses are in good agreement with the experimental findings.

 

Key words: Polymer reflecting gratings, solar cell, holographic interference lithography, power conversion efficiency.
