Synthesis of Cu 2 ZnSnS 4 thin film solar cells by sulfurization of sputtered Sn/Zn/Cu precursors is studied. The sulfurization temperatures were varied, and the morphology, cross section, and composition of the CZTS were investigated by scanning ele

We report the reliability of aluminum-doped zinc oxide (AZO) thin films exposed to harsh environmental conditions of damp heat. Identical sets of the AZO films grown on float glass substrates were subjected to four different controlled environments o

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

Aluminum-doped zinc oxide (AZO) thin film is a viable alternative to tin-doped indium oxide, the dominant transparent conducting oxide used in solar cells. The durability of the AZO thin films grown by atomic layer deposition technique, which is know

We report transmittance and conductivity measurements of aluminum-doped zinc oxide films grown by atomic layer deposition. The results show that the films have 80–90% transmittance in the visible region and good transmittance in the infrared. To ou

High-quality Zn3P2 nanowires are synthesized at a temperature as low as 350 °C using Zn foil and trioctylphosphine by chemical reflux method. Scanning electron microscopy and transmission electron microscopy (TEM) images show their diameters vary fr

Chalcopyrites are important contenders among thin-film solar cells due to their direct band gap and higher absorption coefficient. Copper–Indium–Gallium Sulfide (CIGS2) is a chalcopyrite material with a near-optimum band gap of ~ 1.5 eV. Record e

In a p-n junction photovoltaic (PV) cell, a photon of light produces an electron hole pair if the energy of the photon is at least equal to the band gap of the material constituting the p-n junction. The electrons and holes first diffuse toward the r

In the present contribution, we report a simple and repeatable process for the synthesis of zinc phosphide on two different substrates, zinc foil and zinc evaporated on molybdenum-coated glass. Zinc phosphide has been an important candidate for optoe
