Special Issue Information

Dear Colleagues,

Currently, there is a growing demand for clean and renewable energy resources, due to their high efficiency, promising large-scale applications, and almost zero emissions, to replace fossil fuels as society develops rapidly. To meet the requirement of high performance of energy conversion and catalytic activity, various types of substances including organic, inorganic or hybrid materials have been extensively reported. Moreover, if the materials are realized in the nano-sized dimension, performances could be accelerated.

This Special Issue is open to contributions of nanomaterials for various energy conversion and catalytic applications including batteries, supercapacitors, solarcells, fucells, thermoelectrics, piezoelectrics, triboelectrics, and many other areas.

Plasma-Enhanced Atomic Layer Deposition of TiN Thin Films as an Effective Se Diffusion Barrier for CIGS Solar Cells

Plasma-enhanced atomic layer deposition (PEALD) of TiN thin films were investigated as an effective Se diffusion barrier layer for Cu (In, Ga) Se2 (CIGS) solar cells. Before the deposition of TiN thin film on CIGS solar cells, a saturated growth rate of 0.67 Å/cycle was confirmed using tetrakis(dimethylamido)titanium (TDMAT) and N2 plasma at 200 °C. Then, a Mo (≈30 nm)/PEALD-TiN (≈5 nm)/Mo (≈600 nm) back contact stack was fabricated to investigate the effects of PEALD-TiN thin films on the Se diffusion. After the selenization process, it was revealed that ≈5 nm-thick TiN thin films can effectively block Se diffusion and that only the top Mo layer prepared on the TiN thin films reacted with Se to form a MoSe2 layer. Without the TiN diffusion barrier layer, however, Se continuously diffused along the grain boundaries of the entire Mo back contact electrode. Finally, the adoption of a TiN diffusion barrier layer improved the photovoltaic efficiency of the CIGS solar cell by approximately 10%. Full article
