Silicon (Si) films were deposited on low-cost graphite substrates by the electrochemical reduction of silicon dioxide nanoparticles (nano-SiO) in calcium chloride (CaCl), melted at 855 °C. Cyclic voltammetry (CV) was used to analyze the electrochemical reduction mechanism of SiO to form Si deposits on the graphite substrate. X-ray diffraction (XRD) along with Raman and photoluminescence (PL) results show that the crystallinity of the electrodeposited Si-films was improved with an increase of the applied reduction potential during the electrochemical process.

- Chalcopyrite CuInSe (CISe)-based thin-film solar cells have gained attention since the 1970s, with established technology now leading to commercial products.
- Despite advancements, there are still many unexplored aspects of the materials science and defect physics in CISe-based films and devices that need further research.
- The paper reviews critical issues in CISe materials and devices, including Cu-deficient phases, alkali-metal effects, flexible solar minimodules, and open circuit voltage loss analysis.
Iron pyrite [cubic FeS (cFeS)] is considered as an earth-abundant and low-cost thin-film photovoltaic material. However, the conversion efficiency of cFeS-based solar cells remains below 3%. To elucidate this limitation, we evaluate the optical and electrical characteristics of cFeS single crystals that are grown using the flux method, thus providing us an understanding of the electron transport behavior of cFeS single crystals.
