Improvement in optical and structural properties of ZnO thin film through hexagonal nanopillar formation to improve the efficiency of a Si–ZnO heterojunction solar cell

Combined effect of ZnO nanoripples and solvent additive on the nanomorphology and performance of PTB7-Th: PC71BM organic solar cells

“…As can be seen from figures S2(a), (b) and S3, a change was observed in the absorbance, reflectance and PL spectra for ZnO flat and ZnO NRPs. The obtained results are similar to previously reported results for sol-gel ZnO [13,14,37,38]. Surface composition and chemical states of ZnO NRPs film formed on ITO coated glass substrates were analyzed using XPS and are shown in figures 1(a)-(c).…”

Drastic evolution of point defects in vertically grown ZnO nanorods induced by lithium ion implantation

“…ZnO in the form of one-dimensional nanorods (NRs) has attracted increasing interest for their possible applications in optoelectronic, spintronic, and biosensing devices, such as photoelectrochemical water splitting, 1 ultraviolet (UV) light-emitting diodes, 2 UV photosensors, 3 solar cells, 4 piezoelectronics, 5 gas sensors, 6 and so on. 7–9 Moreover, ZnO NR-based nanodevices have many advantageous properties as compared to conventional devices like low power consumption, large integration density, ultrahigh-speed and frequency.…”

Modelling and analysis of temperature‐dependent carrier lifetime and surface recombination velocity of Si–ZnO heterojunction thin film solar cell

“…Those devices are fabricated by different methods such as spray pyrolysis, thermal evaporation, molecular beam epitaxial, sol–gel method and laser deposition [4]. In addition, some researchers showed improvement of thin ZnO film quality and hence overall performance of SC based on it at high temperature [2, 5]. In some other works in the art, temperature‐dependent diode parameters and current density–voltage (J–V) plot were investigated [6, 7].…”

“…1. Introduction: Heterojunction solar cell (SC) fabricated by deposition of transparent conducting zinc oxide (ZnO) on a single crystalline silicon (c-Si) is a burning topic of present days in photovoltaic industry, because of low-temperature handling and cheapness [1][2][3]. In this regard, superior blue response is a prominent characteristic of heterojunction ZnO-Si SC.…”
