Aluminum-doped zinc oxide (AZO) thin film is a promising candidate for low-cost transparent conductive oxide applications. AZO thin films have good electrical and optical properties; however, their reliability must be carefully considered in manufact

Zinc sulfide has gained popularity in the last few years as a cadmium-free heterojunction partner for thin film solar cells and is seen as a good replacement for cadmium sulfide due to better blue photon response and non-toxicity. In this work, zinc

Cu-doped ZnO film in nanowire structure is synthesized by a closed space flux sublimation and periodic oxidation method at ∼300°C over Si substrate. Oxidative process controlled selfcatalytic VLS mechanism is proposed for the film growth. X-ray di

With a band gap of 0.95 eV and high absorption coefficient (∼105 cm−1), FeS 2 is ideal for use as a p-type heterojunction partner in a solar cell. Although pyrite is abundant in nature, getting the right phase for thin films is difficult due to t
