该协议提供了实现光子上转换增强DSC和细节上如何正确衡量这种装置的方法。 FOM的允许可以预料，在不同光照强度的预期ΔJSC改进了简单的计算，包括1太阳。这里示出的值是不变的光强度（ 图4的插图），为每期望当系统处于低于其饱和度阈值33。与FOM，我们可以标准化TTA-UC或其它非直线UC过程的增强效果，以允许容易地比较。 虽然在本研究中得?...

染料敏化太阳能电池（DSC）的已被宣布为一个有前途的概念，经济实惠的太阳能收集1-3。虽然如此热情，广泛的商业化还没有出现。有许多原因已提出了这一点，与一个迫切的问题是吸收发病的相对高的能量，限制了这些器件4的可实现的光捕获效率。虽然这是可以克服的，从而降低了吸收发病通常伴随着在开路电压的降低，过多地削弱了在电流密度为5，6的任何增益。 DSC中的一般操作涉及从光激发染料的半导体（一般为二氧化钛），其次是氧化染料通过氧化还原介体的再生的电子转移。这两个过程似乎需要大量的驱动力（电势），以进行高效率7 </suP&gt;。有了这样显著固有的损耗，它变得很明显，最佳的吸收发生在这些设备是相当高的能量。为有机光伏（OPV），由于所需的有效电荷分离的大的化学驱动力存在再次类似的问题。因此，上部太阳能到电的转换效率限制到基于这两种技术的单结器件的预测涉及吸收剂具有宽的（有效）的带隙4。 为了克服以上提出的光收获问题，一些方法已被采取。这包括“第三代”8的方法串联结构9，第10和光子上转换11-14。 最近11我们报道的DSC的工作和反电极组成的一体化设备，具有三重态-三重态湮灭基础上转换（TTA-UC）的注册系统到的结构。这TTA-UC元件是能收获穿过活性层发射的红光和化学转换（如在下面详细描述），以更高的能量的光子可能通过DSC的活性层所吸收，并产生光电流。还有要注意有关该系统的两个重要点。首先，TTA-UC比其他的光子上转换系统11许多潜在的优势;其次，它展示了一个可行的架构（证明型原则）为TTA-UC，还有所欠缺的TTA-UC文学到该点的结合。 TTA-UC 15-24的方法涉及“敏化剂”分子的激发，在此情况下钯卟啉，通过光与下面的设备发病能量的能量。单线激敏进行快速系统间跨越到能量最低的三重态。从那里，他们可以传递能量到基态三重接受“射＆＃8217;种类，例如红荧烯，只要传递被允许通过自由能25。红荧烯的第一三线态（T 1）大于它的第一激发单重态（S 1），但在T 2的不到一半的能量一半的能量，也就是说，两个三态激励rubrenes一遇到复杂的可以消灭到举一个单重激发发射剂分子（以及其他在基态）以相当高的概率。其他国家，统计预测，最有可能大力人迹罕至的红荧烯26。然后将单重激发红荧烯分子能够发射光子（按照荧光）与能量足以激发染料在DSC的工作电极。这个过程示于动画1。 TTA-UC提供了许多优点相比其他的UC系统，如广泛吸收范围和不连贯性27，28，使它成为一个有吸引力的选择腠用DSC耦（以及OPV）。 TTA-UC已被证实在相对低的光强度和在漫射照明条件下操作。无论是DSC和OPV是最有效的在低光强的制度。太阳能浓度是昂贵的且仅正当的高效率，成本高的设备。 TTA-UC系统，可在低强度光照条件下的相对高的性能，是由于涉及到与强，宽吸收带敏化剂的发色团在音乐会和长寿命的三线态，其能够扩散的顺序，以与相互反应的物质接触的过程。此外，TTA-UC已被发现具有高的固有效率从动力学研究26。 虽然TTA-UC工作在低的光强度，但仍然（至少在低光强度）与入射光强度和射出光之间的二次关系。这是由于该方法的双分子性质。考虑到对于这一点，报告的不同群体的不同实验条件（尤其是光的强度），择优录取（FOM）系统的数字应采用米乘上转换所提供的性能增强。这FOM被定义为ΔJSC /ʘ，其中ΔJSC是增加的短路电流（通常由积分入射光子的确定载流子的效率，IPCE，有和没有上转换效应）和ʘ是有效的太阳能浓度（基于在相关区域中的光子通量，即敏化剂的Q带吸收）2 29。 在这里，一个协议，用于生产和正确表征集成的DSC-TTA-UC设备被报道，特别关注在设备检测潜在的隐患。希望这将成为在这一领域的进一步工作的基础。

integrating a triplet-triplet annihilation up-conversion system to enhance dye-sensitized solar cell response to sub-bandgap light

染料敏化太阳能电池（DSC）的红色和红外光的反应冷淡是显著妨碍实现更高的光电流，从而提高效率。光子上转换用的三重态 - 三重态湮灭的方式（TTA-UC）是一个有吸引力的技术，对于使用这些否则浪费掉的低能量光子产生的光电流，而不是与以有害的方式将photoanodic性能的干扰。进一步向此，TTA-UC具有许多功能，从其它报道光子上转换技术截然不同，这使得它特别适合于用DSC技术耦合。在这项工作中，经过验证的高性能TTA-UC系统，包括钯卟啉敏化剂和红荧烯发射器，结合了高性能的DSC（利用有机染料D149）于一体的综合设备。该装置示出了一个增强的响应子带隙光随所得的最高网络连接的吸收范围的TTA-UC子单元的gure优异的上转换辅助DSC性能过时。

不同的测量条件下测量的三维显示增强的响应，以影响在下文中更详细地讨论- 图3A。从原始电流密度的增强，应当清楚，这些结果在图4A和4B是归属于上转换，与峰值电流的提高和IPCE增强与吸收光谱的敏化剂，通过在有源层衰减传输匹配良好DSC。 为了避免由激光施力泵浦光束引入测量工件已被调整到在UC层以较大的角度，以?...
