Performance improvement of thin-film silicon solar cells using transversal and longitudinal titanium nitride plasmonic nanogratings

Efficient broadband light absorption in thin-film a-Si solar cell based on double sided hybrid bi-metallic nanogratings

“…Recently, Z. Khezripour et al, proposed titanium nitride nanogratings on top and bottom of TFSC and obtain broadband absorption at longer wavelengths from 600-1100 nm. 24 However, they do not cover the rich energy visible portion of the solar spectrum.…”

Systematic Investigation of the Optical Characteristics of GaAs Solar Cells with Antireflection Coatings and Metallic Nanoparticles Using Finite Element Analysis

“…However, the efficiency of SCs is limited by transmission and thermalization losses . Different strategies are proposed by the researchers in order to enhance the efficiency of SCs through the minimization of these losses, which include the usage of different micro- and nanostructures, such as nanopyramids, nanocones, nanowires, antireflection coatings (ARCs), rough and textured surfaces, plasmonic metal nanoparticles (MNPs), diffraction gratings, and photonic crystals . Using plasmonic MNPs in SCs has recently garnered potential research interest owing to the unique optical properties exhibited by these structures that result in efficient light trapping. , Plasmonic effects are considered to circumvent the transmission losses in thin-film SCs through an enhancement in light absorption with a reduced physical thickness of the absorber layer .…”

“…Using plasmonic MNPs in SCs has recently garnered potential research interest owing to the unique optical properties exhibited by these structures that result in efficient light trapping. , Plasmonic effects are considered to circumvent the transmission losses in thin-film SCs through an enhancement in light absorption with a reduced physical thickness of the absorber layer . The interaction of photons with the metallic nanostructures results in surface plasmon resonance effects, leading to concentrated near-field light, and MNPs improve the efficiency of SCs by increasing the optical path length via far-field scattering effect and surface plasmon resonance effect, causing near-field light concentration . Hence, it is evident that plasmonic enhancement occurs due to various mechanisms, including far-field scattering, near-field enhancement, and resonant energy transfer, and these processes are primarily dependent on the structural dimensions of the MNPs and their location within the SC structures .…”

Enhanced fluorescence of CsPbBr3/ZnO heterojunction enabled by titanium nitride nanoparticles

“…TiN NPs are among the most widely used nanomaterials in optoelectronic devices [24][25][26]. Because the electronic structure of TiN is composed of ionic bonds, covalent bonds, and metal bands, the p-orbital energy level of nitrogen is lower than the Fermi energy level, resulting in movement similar to that of the free electrons of precious metals such as Au and Ag [27,28].…”
