“…However, both ZnO and Al 2 O 3 are also used as ARCs due to their better electrical and optical behavior including good optical transparency, appropriate refractive index and ability to form textured coating [13]. An earlier report also suggests that the TMO films deposited on Si wafer as ARC's demonstrated better device performance compared with a TiO 2 single layer as ARC [14]. However, comparative studies on TMOs as ARC on silicon-based solar cells are indeed fewer.…”

Herein, we report the study on RF-sputtered transition metal oxide thin films of Zinc oxide, Magnesium oxide, and Aluminum oxide as an antireflection coating on silicon-based solar cells and their influence on energy conversion. The transmission spectrum of all sputtered metal oxides was studied using a UV-visible spectrophotometer. The phase formation and microstructure analysis of these sputtered oxides were studied using glass for the destructive test along with the device. The x-ray diffraction and cross-section scanning electron microscopy of sputtered glass confirmed a singlephase structure along with nearly equal desired deposition thickness. The thicknesses of sputtered films were estimated using variable angle ellipsometry and the same was confirmed from cross-section scanning electron micrograph. The chemical composition and oxidation state of thin films deposited on glass were established from x-ray photoemission spectroscopy. The ability of a fabricated device deposited with the antireflection layer in converting photon energy to electrical energy was studied using a solar simulator under 1 sun condition. The ability to collect charge carriers of the antireflection coated device as a function of wavelength was also studied using quantum efficiency measurement.

“…Among the electron‐selective transport materials mentioned above, TiO 2 is one of the few materials that can spontaneously satisfy the dual functions of interfacial passivation and carrier‐selective transport. Many fabrication technologies have been developed to deposit high‐quality TiO 2 layers, such as chemical vapor deposition (CVD), atomic layer deposition (ALD), evaporation, and sol–gel processes . Benefiting from chemical and field‐effect passivation, the ALD/CVD‐deposited TiO 2 layers can effectively passivate a Si surface with a surface recombination velocity down to 10 cm s −1 .…”

Crystalline silicon (c‐Si) heterojunction solar cells featuring dopant‐free and carrier‐selective contacts have drawn considerable attention due to their potential in achieving high efficiency with extremely simple fabrication procedures. Here, a low‐temperature thermal oxidation process is developed to fabricate a titanium dioxide (TiO2) ultrathin layer directly from a titanium (Ti) film that was predeposited onto Si substrates, leading to a surface recombination velocity as low as 15 cm s−1. Detailed interfacial and structural characterizations show that the excellent contact passivation property was mainly attributed to the amorphous nature of TiO2 and the presence of a Ti‐contained SiOx interlayer. By applying this ultrathin TiO2 layer as a passivating‐contact layer, test heterojunction solar cells employing a core structure of poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/n‐Si/TiO2 obtained an efficiency as high as 14.6% (only 13.0% for the reference device), demonstrating the potential for applications of this thermal oxidation‐derived TiO2 layer in dopant‐free heterojunction solar cells.

“…AR films themselves are well known for uses in many optical systems including photovoltaics and displays which require reduced reflection and hence higher transmission of light. For example Hocine et al [8] showed a 3% (absolute) increase in solar cell efficiency on addition of an AR film. In addition the use of silica films has included dual functionality AR with both superhydrophobic [9] and superhydrophilic [10] surfaces.…”
