Cell Performances of Inorganic-Organic Hybrid Solar Cells Using Fluorosilicate/Phosphorus Oxide Composite Microparticles

Abstract

We report on the structural characterization and the photovoltaic performances of novel photoelectric conversion materials fabricated by simplified and cheap procedures based on a chemical approach. Our prepared composite microparticles were composed of fluorosilicate/phosphorus oxide holding together by ammonium. When such composite microparticles were used in the active layer of the hybrid solar cells, the relatively high Jsc was obtained by causing the adequate carrier transport from the active layer to each electrode, attaining the best photovoltaic performance with a PCE of 4.45 %. These findings indicate that the fluorosilicate/phosphorus oxide composite microparticles have sufficient ability as the photoelectric conversion materials.

Configuration Effect of Antireflection Layer on Photovoltaic Performance of Silicon/PEDOT:PSS Hybrid Solar Cells

“…To investigate the effect of the texture of the antireflection layer on the photovoltaic performance of the micro-textured hybrid solar cells, two types of micro-tex-J Nanotech Mater Sci | volume 4: issue 1 Silicon/PEDOT:PSS Hybrid Solar Cells www.ommegaonline.org tured structures were fabricated on the substrate's surface. The first structure was the micro-desert textured configuration, which was produced on the substrate's surface at room temperature by using a simplified and cheap version of the vapor acid chemical etching (VACE) technique, in which only one piece of substrate and 2 mL of a HF/HNO 3 mixed solution were hermetically sealed in a polymeric container (without a vacuum) for 24h [13] . When using the VACE technique, ammonium hexafluorosilicate ((NH 4 ) 2 SiF 6 ) microparticles were formed on the micro-desert textured configuration [13] .…”

In this study, the micro-desert textured configuration was obtained by dissolving the microparticles in pure water for 10 min.…”

“…This was prepared on the substrate's surface at room temperature by using the two-step metal-assisted chemical etching (MACE) technique [12][13][14] . First, the substrate was dipped in an aqueous solution containing 0.02 mL of 40% AgClO 4 , 0.02 mL of 50% NaOH and 100 mL of pure water for 20 min to deposit the Ag nanoparticles.…”
