“…41,42) The reflectance curves also showed similar behaviors in all films, although the positions of the maxima and minima reflectance in the wavelength range of 400 1000 nm for the 50.4Te film shifted to low wavelength compared with those for 49.2Te and 47.9Te films. The reflectance of the ¡-MnTe films (10%³50%) was higher than that of CdTe (10%³30%) 43) and CIGS (5%³20%) 44) in the wavelength range of 4001100 nm.

The optical and electrical properties of MnTe films were investigated to ascertain the feasibility of their use in solar cell applications. Three ¡-MnTe thin films with different composition, i.e., Mn-47.9 at% Te, Mn-49.2 at% Te, and Mn-50.4 at% Te, were prepared using RF magnetron sputtering. All the films demonstrated a high light absorption coefficient (0.2 © 10 5 0.8 © 10 6 cm ¹1) and an optimal indirect band gap (1.37 1.52 eV) for solar cell applications. Furthermore, all of them exhibited p-type conductivity, with the Mn-47.9 at% Te film demonstrating three to four times higher carrier mobility (5.2 cm 2 •V ¹1 •s ¹1) than the Mn-50.4 at% Te film (1.6 cm 2 •V ¹1 •s ¹1).

“…Over the past years, several architectures (cones, domes, pillars, pyramids) have been used to mimic the moth‐eye texture. [ 159 ] In a previous work, [ 43 ] optical simulations through the FDTD method were performed to study the effect of pyramidal array trenches on the AZO layer in ultrathin CIGS devices, as shown in Figure a. Two different pitch sizes of the modeled array were studied, 1000 and 50 nm.…”

Light management strategies are of utmost importance to allow Cu(In,Ga)Se2 (CIGS) technology market expansion, as it would enable a conversion efficiency boost as well as thinner absorber layers, increasing sustainability and reducing production costs. However, fabrication and architecture constraints hamper the direct transfer of light management architectures from other photovoltaic technologies. The demand for light management in thin and ultrathin CIGS cells is analyzed by a critical description of the optical loss mechanisms in these devices. Three main pathways to tackle the optical losses are identified: front light management architectures that assist for an omnidirectional low reflection; rear architectures that enable an enhanced optical path length; and unconventional spectral conversion strategies for full spectral harvesting. An outlook over the challenges and developments of light management architectures is performed, establishing a research roadmap for future works in light management for CIGS technology. Following the extensive review, it is expected that combining antireflection, light trapping, and conversion mechanisms, a 27% CIGS solar cell can be achieved.

“…been extensively studied by numerous research groups. [2][3][4][5] Particularly, bioinspired micro-or nano-architectures can reduce the surface reflection in wide ranges of wavelengths and angles of incident light due to the formation of a gradient effective refractive index profile between air and the substrates. [6][7][8][9] Many techniques are available for fabricating micro-or nano-architectures, such as e-beam lithography, 10 photolithography 11 and laser interference lithography.…”

Fabricating omnidirectional low-reflection films by nano-imprinting method for boosting solar power generation of silicon-based solar cells

Low-reflection polyethylene terephthalate (PET) films are fabricated with nanoimprinting method. The films are then used to cover polycrystalline silicon solar cells. The morphological and optical properties of films are investigated. The films have periodic cylinder-like nanostructures and relatively low reflectivity in light incident angle ranging from 30 • to 60 • . The nanostructures are with a period of 600 nm and height of 90 nm. Besides, the polycrystalline Si solar cells covered with the films exhibit 12% more power generation than the cells covered with glass. Nano-imprinting method offers a cost-effective approach to fabricate omnidirectional anti-reflection films, which could boost the power generation of Si solar cells. Additionally, the films also have potential applications in different types of solar cells due to its facile fabricating process.
