在金属上卷对卷生产染料敏化太阳能电池的一个限制步骤是二氧化钛烧结(10-30 分钟)。近红外(NIR)加热是一项新的工艺创新，它直接加热钛基板，从而快速去除粘结剂并进行烧结。在不同功率的近红外加热(12.5 S)下，钛的温度分别为545、685和817°C，电池的效率分别为2.9、2.8和2.5%。在常规烤箱(1800 S)中，在500、600和800°C下制备相同的电池，效率分别为2.9%、2.6%和0.2%。近红外烧结速度超快，工艺窗口宽，是金属快速制造的理想选择。版权所有©2010 John Wiley&Sons，Ltd.
A limiting step to roll‐to‐roll production of dye‐sensitized solar cells on metals is TiO2sintering (10–30 min). Near infrared (NIR) heating is a novel process innovation which directly heats titanium substrates giving rapid binder removal and sintering. NIR heating (for 12.5 s) at varying power gave titanium temperatures of 545, 685 and 817°C yielding cells with efficiencies of 2.9, 2.8 and 2.5%. Identical cells prepared in a conventional oven (1800 s) at 500, 600 and 800°C gave 2.9, 2.6 and 0.2% efficiency. NIR sintering is ultrafast and has a wide process window making it ideal for rapid manufacturing on metals. Copyright © 2010 John Wiley & Sons, Ltd.
