抗反射涂层

Abstract(#br)Several developing solar cell technologies—including perovskite cells, thin-film cells, epitaxially grown cells, and many tandem cells on silicon—have fabrication constraints that require a planar front surface. However, flat front surfaces result in large reflection losses and poor light trapping within the cell. We investigate scattering layers made from polydimethylsiloxane (PDMS) polymer carrying a random-pyramid texture to reduce such losses.

Abstract(#br)A low-cost antireflection (AR) coating of polydimethylsiloxane (PDMS) with wrinkle surface structure is demonstrated. The surface modulations with controllable amplitude and period are experimentally performed by plasma surface oxidation of a pre-stretched PDMS followed by removal of the applied mechanical strain. The period and the aspect ratio of the PDMS wrinkle are dependent on plasma treatment time in the process of surface modification.

Abstract(#br)Multiscale array (MSA) structures are present to reduce the front-side surface reflection loss of solar cells, which consists of nanostructure patterns spanned across the curved surface of micrometer-sized plano-concave cylindrical arrays. The MSAs are fabricated using flexible polydimethylsiloxane (PDMS) polymer by simple template replication together with surface modification technique and characterized by atomic force microscopy (AFM) and scanning electron microscopy (SEM).
