“…When considering that the cost per unit area can be very high for high efficiency modules, the importance of such approaches becomes prominent. As an alternative to the vacuum-processed SiN x ARC, TiO 2 and its multilayer structures have been introduced in earlier decades [13][14][15], due to its good optical properties and high refractive index to enhance the light absorption capability of silicon solar cells. In our previous studies, TiO 2 , Al 2 O 3 /TiO 2 , and ZrO 2 /TiO 2 ARC films were introduced [16][17][18] based on spin coating and spray deposition techniques.…”

Abstract:In this work, we introduce a totally vacuum-free cost-efficient crystalline silicon solar cells. Solar cells were fabricated based on low-cost techniques including spin coating, spray pyrolysis, and screen-printing. A best efficiency of 17.51% was achieved by non-vacuum process with a basic structure of CZ-Si p-type solar cells. Short circuit current density (J SC ) and open circuit voltage (V OC ) of the best cell were measured as 38.1 mA·cm −2 and 596.2 mV, respectively with fill factor (FF) of 77.1%. Suns-Voc measurements were carried out and the detrimental effect of the series resistance on the performance was revealed. It is concluded that higher efficiencies are achievable by the improvements of the contacts and by utilizing good quality starting wafers.

“…Antireflective coatings (ARCs) are of great interest of a wide range of industries and applications especially including ophthalmics, optics, flexible displays, bio−engi− neering, energy generation, decorative and barrier coatings for pharmaceutical and food products [1][2][3][4]. Coatings made from thin films can modify electrical, mechanical and/or optical properties of a solid base material in a cost−effective way.…”

In this paper designing, preparation and characterization of multifunctional coatings based on TiO2/SiO2 has been described. TiO2 was used as a high index material, whereas SiO2 was used as a low index material. Multilayers were deposited on microscope slide substrates by microwave assisted reactive magnetron sputtering process. Multilayer design was optimized for residual reflection of about 3% in visible spectrum (450–800 nm). As a top layer, TiO2 with a fixed thickness of 10 nm as a protective film was deposited. Based on transmittance and reflectance spectra, refractive indexes of TiO2 and SiO2 single layers were calculated. Ultra high vacuum atomic force microscope was used to characterize the surface properties of TiO2/SiO2 multilayer. Surface morphology revealed densely packed structure with grains of about 30 nm in size. Prepared samples were also investigated by nanoindentation to evaluate their protective performance against external hazards. Therefore, the hardness of the thin films was measured and it was equal to 9.34 GPa. Additionally, contact angle of prepared coatings has been measured to assess the wetting properties of the multilayer surface.

“…The approach of fabricating AR films splits into two broad categories i-Bottom up and ii-Top down approach. The bottom up fabrication includes methods such as sol-gel processing [55][56][57][58] , chemical vapour deposition (CVD) techniques [59][60][61] , magnetron e-ISSN: 2321-6212 p-ISSN: 2347-2278 sputtering [52,62] , plasma-enhanced chemical vapour deposition [63][64][65] or physical vapour deposition (PVD) techniques [66,67] . The top down approach is limited to wet and dry etching methods.…”

Antireflective coatings (AR) are widely applied to eliminate the unwanted surface reflections from the AR coated substrate. In different optoelectronic devices, AR coatings have potential usage in photovoltaic solar cells, sensors, display devices, automobile industries to reduce reflectance, glare and enhance light transmittance. Natural phenomenon inspires researchers, and they generate bionic AR coatings copying the nature such as moth eyes, or cicada wings to fabricate efficient light harvesting AR coatings. In the current review article, we analyse and evaluate critically the progress and recent development in the fabrication of AR thin films comprising organic coatings, inorganic coatings, polymer AR coatings and bionic AR coatings. We predominantly emphasise the AR coatings fabrication by different methods and pinpoints the technological challenges in their real-world reliability. Finally, we address the future challenges and potential strategies for their upcoming prospect.
