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.

这种中心的合作旨在解决一系列研究机会，这些研究机会需要将光电材料和设备工程与针对大面积太阳能电池和LED的最先进的光管理密切整合。该协作使Amolf LMPV集团因其在太阳能电池的“光管理”方面的工作认可，以与薄膜钙钛矿和有机太阳能电池和LED的剑桥研究计划紧密合作。 AMOLF活动集中在荷兰太阳能细胞研究的非常强大的“国家实验室”框架中，并带来了在英国没有系统地发展的优势。现在，用卤化物钙钛矿制成的薄膜二极管现在支持具有出色电子特性的太阳能电池和LED，但是使用/超耦合的轻度挑战可以限制性能。对于钙钛矿LED来说，这是一个特别的挑战，目前轻度耦合限制为20％。通过利用钙钛矿的特殊发光特性（包括光子回收），并通过工程的光学结构来朝前方向上耦合，将提高到100％的向前耦合。一种将太阳能电池改善超出单一开关限制的一种方法是，从单层材料中获得了一个有机材料的高度摄影师，从而获得了一个能力的摄影师，从而获得了较高的摄影作品，这是一个能力的效果，这是一个能力的效果，这是一个能力，该过程是单一的摄影作品，这是一个能力，它是一个能力的，这是一个能力的，这是一个能力，可以通过单层的效果来提高单声道，这是一个能力，它是单一的能力，该过程是单一型号的效果。低能量的三胞胎激子态。剑桥已经开创了单线裂变的科学，并开发了光子乘数的概念。在这个全光薄膜设备中，入射的高能光子（<540nm）将转换为两个低能的光子，每个光子在约1000 nm左右，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，这些设计将这些IR光子发射到SI太阳能电池中，而无需在模块中引入光损耗。
