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.

Twoforone（2FOR1）的目的是将分子间隔剂在SF-Strategies中的作用在基于机制的设计中，以在最大的可达到的电动电力最大程度上提高实用太阳能电池的光转换效率至200％。 基于所有设备开发的基本问题是如何优化高SF效率的分子结构。 我们的方法是结合超快光谱（即超快电子吸收和红外线）和新定制的SF材料（即实施广泛的多功能分子间隔仪），以提供有关载流子乘法和优化的概念概念。 只有对SF分子机制的有针对性的深入理解才能为实现在能量转化方案中证明载体乘法所需的复杂水平铺平道路，并优化其能量产量。
