A study of the optical properties of wide bandgap oxides for a transparent photovoltaics platform

Abstract

Transparent photovoltaics (TPVs), a see-through energy production platform that allows visible light to pass while absorbing harmful ultraviolet light, are the backbone of invisible onsite power generation. To improve the...

Ti‐Doped ZnO Thin Films‐Based Transparent Photovoltaic for High‐Performance Broadband and Wide‐Field‐of‐View Photocommunication Window

“…The visible transmittance values remain almost unchanged even after the Ti doping, and a sharp fall in the transmittance spectra was observed for all the films below 380 nm due to the materials' band edge absorption. The bandgap values of these films were estimated by using the Tauc plots, [19] as shown in Figure 1h. Bandgap values almost remain the same for TZ0, TZ10, and TZ15 films of about 3.24 eV and this value slightly increases to 3.25 and 3.26 eV for TZ25 and TZ35 films, respectively.…”

“…The highest n and k values of 2.35 and 0.07 were obtained in the UV region for undoped ZnO films, which is at par with our previous study. [19] The dielectric constant (ε r ) values for these films were estimated by using Equation ( 2), [19]…”

“…[7,17] Metal oxides with wide bandgap are essential for transparent photoelectric devices due to their high ultraviolet (UV) photon absorption ability. [18,19] Zinc oxide (ZnO), with a suitable bandgap value of 3.3 eV, strong light-matter interactions, earthabundant, non-toxicity, strong exciton, and tunable optoelectronic properties, is an ideal material for high-performance transparent photoelectric devices. [20,21] However, most ZnObased photoelectric devices reported so far show excellent performance in the UV region but poor performance in the visible region due to its wide bandgap.…”

From Flora to Solar Adaptive Facades: Integrating Plant-Inspired Design with Photovoltaic Technologies

“…Nevertheless, their transparency and aesthetics confine their integration into electronic devices and city landscapes. Dye-sensitized and organic PV devices offer more effective transparency but are restricted by low PCEs for large areas and poor stability [96,97] as cited in [98]. One action that has been taken to overcome these boundaries is the improvement of stable transparent PV (TPV) devices.…”

“…This capability facilitates on-site power generation and incorporates transparent device features. TPV devices exhibit considerable potential, making them a suitable choice for integration in building applications [99][100][101] as cited in [98], which can be the focus of future research for integration with biomimetic designs.…”
