Abstract |
水熱処理によって合成した水酸化物前駆体ナノシートを焼成して, 近紫外光照射により赤色に発光するY2O3 : Bi3+, Eu3+ナノシートを作製した。ポリエチレンイミンを吸着させて正に帯電したナノシートの分散液を調製した。一定の電圧を印加して透明導電性基板上に電気泳動電着によって蛍光ナノシートを堆積した。さらにポリビニルピロリドンをコーティングした。この膜試料が市販の単結晶シリコン太陽電池の特性に与える影響を評価した。
Y2O3 : Bi3+, Eu3+ nanosheets, which emit red light under near-UV irradiation, were obtained by calcining hydroxide precursor nanosheets synthesized through a hydrothermal method. An aqueous dispersion of positively charged Y2O3 : Bi3+, Eu3+ nanosheets with polyethyleneimine adsorbed to the surface was prepared for their deposition. Fluorescent nanosheets were electrophoretically deposited on a transparent conductive substrate under a constant voltage. Next, polyvinylpyrrolidone was coated on the film. The effects of the PVP-coated film samples on the properties of a commercial monocrystalline silicon photovoltaic module were evaluated.
