This Centre-to-Centre collaboration addresses a set of research opportunities that require the close integration of optoelectronic materials and device engineering with state-of-the-art light management for large area solar cells and LEDs. The collaboration brings the AMOLF LMPV group, recognised for its work in 'light management' for solar cells, to work closely with the Cambridge research programme on thin-film perovskite and organic solar cells and LEDs. The AMOLF activity is centred in the very strong 'national laboratory' framework of solar cell research in the Netherlands, and brings strengths that have not been systematically developed in the UK. Thin-film diodes made with lead halide perovskites now support solar cells and LEDs with excellent electronic properties, but challenges with light in/outcoupling can limit performance. This is a particular challenge for perovskite LEDs for which light outcoupling is currently limited to 20%. By harnessing the special luminescent properties of perovskites, including photon recycling, with engineered optical structures, the outcoupling in the forward direction will be raised towards 100%.One way to improve a solar cell beyond the single-junction limit is to harvest the high-energy part of the solar spectrum with an organic material capable of singlet fission, a process by which the energy from one high-energy photon is shared between two lower-energy triplet exciton states. Cambridge has pioneered the science of singlet fission and developed the concept of the Photon Multiplier. In this all-optical thin-film device, incident high-energy photons (<540nm) will be converted into two low-energy photons, each at around 1000 nm, which can then be absorbed by a silicon solar cell underneath. The challenge to be undertaken here is to develop suitable photonic designs that direct the emission of these IR photons towards the Si solar cell without introducing optical losses in the module.

这种中心对中心的合作解决了一系列研究机会，这些机会需要将光电材料和器件工程与大面积太阳能电池和LED的最先进的光管理紧密结合起来。此次合作使AMOLF LMPV小组与剑桥薄膜钙钛矿和有机太阳能电池和LED研究计划密切合作，该小组因其在太阳能电池“光管理”方面的工作而受到认可。AMOLF活动集中在荷兰非常强大的太阳能电池研究“国家实验室”框架内，并带来了英国尚未系统开发的优势。用卤化铅钙钛矿制成的薄膜二极管现在支持具有优异电子性能的太阳能电池和LED，但光输入/输出耦合的挑战可能会限制性能。这对于钙钛矿LED来说是一个特别的挑战，因为光耦合目前被限制在20%。通过利用钙钛矿的特殊发光特性，包括光子再循环，以及工程光学结构，向前方向上的外耦合将提高到100%。改进太阳能电池超过单结极限的一种方法是利用能够单线态裂变的有机材料收集太阳光谱的高能部分，一个高能光子的能量在两个低能三重态激子之间共享的过程。剑桥是单态裂变科学的先驱，并提出了光子倍增器的概念。在这种全光学薄膜器件中，入射的高能光子（<540 nm）将被转换为两个低能光子，每个光子的波长约为1000 nm，然后可以被下面的硅太阳能电池吸收。这里要面临的挑战是开发合适的光子设计，将这些IR光子的发射导向Si太阳能电池，而不会在模块中引入光学损耗。
