Attachment of eosin Y onto TiO2 electrode was carried out using super critical CO2 as a solvent. The solar cell composed of an electrode which prepared under the condition of 493 K and 25 MPa in super critical CO2 , showed an efficient fill factor as high as 95% (a Xe lamp with a 517 nm band pass filter). The dye was supposed to keep its structure under such sever conditions. Super critical CO2 made possible to carry out the attachment of dye at high temperature in a uniform phase.
使用超临界
CO2作为溶剂,将
曙红Y附着到TiO2电极上。在超临界 中,在493 K和25 MPa条件下制备的电极组成的太阳能电池显示出高达95%的有效填充因子(带517 nm带通滤波器的
氙灯)。
染料在这种苛刻的条件下应该保持其结构。超临界 使得在高温下以均匀相附着
染料成为可能。
