The goal of TwoforOne (2FOR1) is dissecting the role of molecular spacers in SF-strategies towards a mechanism-based design to boost the light-conversion efficiencies in practical solar cells to 200% at a maximum attainable electromotive force. The essential question, which underlies all device development is how to optimize molecular structures for high SF-efficiency. Our approach is to combine ultrafast spectroscopies (i.e., ultrafast electronic absorption and infrared) and newly tailored SF-materials (i.e., implementing a broad scope of multifunctional molecular spacers) to offer proof-of-concept regarding carrier multiplication and optimization thereof. Only the targeted in-depth understanding of the molecular mechanism of SF can pave the way to accomplishing the level of sophistication needed for demonstrating carrier multiplication in energy-conversion schemes and optimizing their energy yield.

TwofOne（2FOR1）的目标是剖析分子间隔物在SF策略中的作用，以实现基于机制的设计，从而在最大可达到的电动势下将实际太阳能电池的光转换效率提高到200%。 作为所有器件开发基础的基本问题是如何优化分子结构以获得高SF效率。 我们的方法是将联合收割机超快光谱（即，超快电子吸收和红外）和新定制的SF材料（即，实现宽范围的多功能分子间隔物）以提供关于载体倍增及其优化的概念验证。 只有有针对性地深入了解SF的分子机制，才能为实现在能量转换方案中演示载流子倍增和优化其能量产额所需的复杂程度铺平道路。
