“…CEA has developed a proprietary process called Boostream [7][8][9] originally meant for colloidal lithography and here applied to the deposition of self-assembled GNS monolayers on large surfaces. This type of colloidal lithography is often applied to other areas, such as mechanics, sensors or photonics.…”

“…Along with periodical structures EOT exists in polycrystalline geometries, too. Such kind of structures naturally appears in colloidal self-assembly process, where a close-packed array of nano/micro spheres is deposited onto a substrate using one of numerous implementations of the Langmuir-Blodgett technique [18][19][20][21]. A number of works consider EOT-supporting plasmonic structures prepared via metal deposition into the interstices between colloidal particles [22,23] or by covering of a nanosphere mask with a thin metal film [24] with possible subsequent removal of particles [25,26].…”

The work considers the effect of extraordinary optical transmission (EOT) in polycrystalline arrays of nanopores fabricated via nanosphere photolithography (NPL). The use of samples with different qualities of polycrystalline structure allows us to reveal the role of disorder for EOT. We propose a phenomenological model which takes the disorder into account in numerical simulations and validate it using experimental data. Due to the NPL flexibility for the structure geometry control, we demonstrate the possiblity to partially compensate the disorder influence on EOT by the nanopore depth adjustments. The proposed experimental and theoretical results are promising to reveal the NPL limits for EOT-based devices and stimulate systematic studies of disorder compensation designs.

“…The fabrication of the textured glass substrates is based on the deposition of a monolayer of silica spheres on a SLG substrate followed by an annealing step to burry these spheres into the glass. An enhanced Langmuir-Blodgett technique oriented to very large planar or non-planar substrates (called Boostream) is used to deposit this monolayer of spheres as described in reference [12]. This method allows homogeneous deposition on large surface (N 1 m 2 ) at low cost (CEA estimation for spheres deposition is 3 €•m −2 ).…”

Influence of coevaporation process on CIGS solar cells with reduced absorber thickness and current enhancement with periodically textured glass substrates

et al. 2017

This study shows the fabrication of CIGS solar cells with various absorber thicknesses synthesized with two different methods: the classical 3-stages coevaporation process and a 1-stage coevaporation process. Structural characteristics and photovoltaics properties as function of absorber thickness are described. 1-stage coevaporation process gives lower efficiencies for CIGS solar cells with nominal absorber thickness (~2000 nm) but performs similarly or even better when the absorber thickness is decreased down to 600 nm. Periodically textured glass substrates with different feature sizes have been fabricated and used to increase current in 1-stage coevaporated CIGS solar cells. A current improvement up to 4.1 mA•cm −2 (6% relative) has been obtained leading to an increase in efficiency up to 5% relative. A maximum increase has been found when texturation size is similar to CIGS absorber thickness.
