Porous Silicon Oxide Anti‐Reflection Coating for Solar Cells

Abstract

A very useful anti‐reflection (AR) coating, having characteristics quite similar to silicon monoxide, has been grown on P+N solar cells by a simple technique. ESCA, infrared absorption, and ellipsometry analysis of the films indicated that they consist of silicon oxide with some bound hydrogen. Some added advantages of the new AR coating are described.

Correlation between reflectivity and photoluminescent properties of porous silicon films

“…numerous interesting silicon nanostructures such as PS. the arrays of nanocone, nanopillars, nanorods and nanowires have been developed by traditional or newly invented methods, and many interesting optical or electrical properties were obtained, but the space remained for constructing and developing novel silicon nanostructures is still tremendous [8], The first application of photoelectrochemically formed PS layers grown on Si wafers as an ARC was reported by Prasad et al [9].…”

Porous Silicon and Solar Cells

“…Formation of porous silicon (PS) on the surface of silicon solar cells provides a promising approach to minimize reflection ( Fig. 1) and replace conventional ARC layers on cells (Prasad et al 1982;Menna et al 1995;Yerokhov and Melnyk 1999;Dzhafarov 2013).…”
