Textured Antireflection Sticker Film for Efficient Solar Cells

For highly efficient solar cell, it is necessary to understand all the light loss in the solar cell and develop broadband light harvesting. This thesis reports a polydimethylsiloxane (PDMS) film composed of random sized inverted pyramidal structure (RSIPS) fabricated by simple and cheap process that displays excellent optical properties. The RSIPS-PDMS film shows high optical haze which increase the light scattering and low reflection because of a linear grading of the effective refractive index profile from the air to glass or silicon layer. By applying the RSIPS-PDMS on Si solar cell, the current density and efficiency was improved (i.e., 35.9mA/cm^2, 16%) compared to those of reference device (i.e., 33.1mA/cm^2, 14.9%). Also, a polymer solar cell (PSC) with RSIPS-PDMS film has improved current density and efficiency. The RSIPS-PDMS film is suitable for an antireflection film of diverse solar cells.
