The foundation of a colloidal lithography system is the electrostatic attachment of colloids in a reasonably ordered pattern on a charged surface. However, as the colloids dry, capillary pressures cause them to cluster into aggregates.
Large hydrophilic particles are particularly susceptible to these capillary forces. The aggregation of large silica particles deposited on glass substrates that had previously been treated with polyallylamine (PAH), a polycation, is examined using a variety of experimental techniques in this research.
These methods involve sandwiching smaller colloids between the larger ones or covering the deposit with a layer of macromolecules (such as albumin or PAH). SEM measurements reveal that adding PAH and much better adding albumin on top of adhering colloids improves the results.
It’s interesting to note that while surfaces obtained through calcination have very hydrophilic surfaces, those obtained through silica colloid deposition and albumin adsorption have very high water contact angles (95°). In light of the Wenzel and Cassie-Baxter models, this is discussed. To sum up, the suggested technology enables the creation of a soft and low-cost soft nanoscale topographic pattern with controllable wettability on vast surface regions.
The Global Colloidal lithography system Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The development of nano/micro-technological solutions capable of improving photovoltaic (PV) performance without considerably raising costs has been pushed by the pursuit of ever-more efficient, dependable, and economical solar cells. One of the most pertinent methods relies on light management through photonic wavelength-sized structures because they enable significant efficiency gains by lowering reflection and trapping light inside the devices.
Additionally, by effectively repelling water, improved microstructured coatings provide self-cleaning capabilities, which lowers the buildup of dust and other particles that produce shadowing.
However, when it comes to commercial adoption, nano/micro-patterning solutions can only be used in the PV sector if integrating them doesn’t result in significant additional costs or delays in the production of high-throughput solar cells.
Colloidal lithography system , a low-cost, highly scalable soft-patterning technology that enables nanoscopic precision over infinitely large areas, and hence regarded as the preferred structuring method for PV.
With the help of fine-tuning particular factors, such as colloidal size, form, monodispersity, and final arrangement, CL makes it possible to create a variety of templates and masks for use in diverse contexts. This review aims to combine a number of current, well-known publications on this issue and how they may affect the development of solar power in the future.
