Nanoimprint Lithography for Solar Cell Applications

Nanoimprint lithography (NIL) has emerged as a noteworthy technology in the realm of fabricating micro- and nanostructures with anti-reflective characteristics for diverse solar cell applications. This advanced technique presents a cost-effective approach, accompanied by a vast array of design versatility, thereby facilitating enhanced flexibility in optimizing the efficiency of photovoltaic systems. NIL boasts a multitude of applications across nearly all solar cell types. This article delves into the utilization of NIL and its influence on power conversion efficiency within various solar cell categories, encompassing silicon-based solar cells (including monocrystalline, polycrystalline, amorphous, microcrystalline, and silicon heterojunction solar cells), third-generation solar cells (such as copper indium gallium diselenide, dye-sensitized, perovskite, and organic solar cells), compound solar cells, nanowire-based solar cells, and bio-inspired solar cell structures. By capitalizing on the multiscale textures achievable through the NIL process, substantial advancements can be made in further elevating the performance of solar cells.
