“…Following previous research, physical information regarding the constituent materials, including their refractive indices and extinction coefficients, was used in the numerical modeling of a CIGS solar cell. 24 All simulations were performed under a 1-sun standard air mass 1.5 global (AM1.5G, 100 mW cm À2 ) light spectrum. Theoretical calculations revealed the optimization of PS nanospheres on the CIGS solar cell.…”

Broadband and omnidirectional light harvesting is important in photovoltaic technology because of its wide spectral range of radiation and the sun's movement. This study reports the fabrication and characterization of zinc oxide (ZnO) dandelions on Cu(In,Ga)Se2 (CIGS) solar cells. The fabrication of dandelions involves the combination of self-assembled polystyrene (PS) nanospheres and the hydrothermal method, which is one of the simplest and cheapest methods of fabricating a three-dimensional, closely packed periodic structure. This study also investigates the optimization on dimension of the PS nanospheres using the rigorous coupled-wave analysis (RCWA) method. This study uses an angle-resolved reflectance spectroscope and a homemade rotatable photo I-V measurement to investigate the omnidirectional and broadband antireflections of the proposed dandelion structure. Under a simulated one-sun condition and a light incident angle of up to 60°, cells with ZnO dandelions arrays enhanced the short-circuit current density by 31.87%. Consequently, ZnO dandelions are suitable for creating an omnidirectionally antireflective coating for photovoltaic devices.

“…b), ZnO nanorod arrays are electrodeposited onto the Al‐doped zinc oxide (AZO) window layer of CIGSe solar cells to serve as an anti‐reflection coating (ARC). The successful use of ZnO nanorods, acting in this role as a sub‐wavelength structure, has already been simulated and experimentally proven . Here, we have applied the ZnO nanorods as an ARC on industrially produced CIGSe solar cells (a cross‐section SEM image of such a prepared solar cell is shown in the abstract) and examined how beneficial and plausible it is to incorporate such a coating as a solar module manufacturing step.…”

ZnO nanorod arrays placed within the architecture of the Cu(In,Ga)Se2 solar cell present promising concepts to maximize photoconversion by optical and electrical enhancement. Three different Cu(In,Ga)Se2 solar cell architectures utilizing ZnO nanorods are introduced. New technological insights are given for electrodeposited ZnO nanorod anti‐reflection coatings, examining the reflectance of devices before and after encapsulation. For the first time, device results from superstrate and bifacial CIGSe solar cells incorporating ZnO nanorods are presented. The potential benefits as well as technological aspects of fabricating these new architectures are discussed. Scanning electron microscope picture of the cross‐section of an industrially produced CIGSe solar cell with a ZnO nanorod anti‐reflection coating.

These ordered nanostructures increase light capture via diffused reflections between nanostructure arrays, enhancing the charge separation and transport via their unique inherent morphological, electrical, and optoelectronic properties (e.g., their high surface‐to‐volume ratio).…”

In this work, pneumatic spray pyrolysis was used to deposit Cu2ZnSnS4 kesterite thin film layers onto soda lime glass substrates/Mo coated substrates (substrate configuration). Furthermore, pneumatic spray pyrolysis was also tested as a potential way to grow kesterite thin film layers on ZnO nanorod arrays on SnO2:F coated glass substrates (superstrate cell configuration). In this case semi‐transparent samples were obtained. A summary of the process parameters optimization to effectively coat the ZnO nanostructures is presented. In both solar cell configurations, absorbers were selenized at 400–500 °C and compared. For the substrate configuration, we present a device with a power conversion efficiency of 1.86%, Voc = 292 mV, Jsc = 16.2 mA/cm2 and FF = 39.6%.
