HERALD aims to instigate a step-change in how smart devices are powered by developing new classes of pnictogen-based semiconductors to more efficiently collect the widely-available energy from lighting inside buildings. Such energy can be renewably harvested with indoor photovoltaics (IPV), which is highly appealing for powering the billions of autonomous smart devices driving the fourth industrial revolution. However, industry-standard IPV (hydrogenated amorphous silicon; a-Si:H) have efficiencies up to only ~20%, with most commercial devices <10% efficient.HERALD will develop IPV from novel classes of rudorffites and chalcohalides, which have potential to reach >48% efficiency under indoor lighting. These are low-toxicity, high-stability materials based on the pnictogens bismuth and antimony, and their considerable potential for indoor light harvesting is just starting to emerge. HERALD will transform these novel compounds into leading IPV using a hierarchical characterisation approach, from the macro- to near-atomic-scale. Along the way, fundamental understanding will be gained to learn what the performance-limiting factors are and how they can be systematically mitigated. The endpoint will be high-performing, durable test devices with low environmental impact. The materials will be rapidly grown at scale using a novel plasma-spray technique, and the IPV prototyped in commercial smart devices.The pnictogen-based IPV developed can have a transformative impact on smart devices by decreasing their reliance on being powered only by batteries, which need to be regularly replaced, creating significant waste. The new IPV can be deployed without harming the environment and will harvest more power than a-Si:H IPV to sustain smart devices with more advanced capabilities. The pioneering development of pnictogen-based semiconductors will also push them forward for numerous PV, from clean solar fuel production to radiation detection for medical imaging.

HERALD 旨在通过开发新型磷元素半导体来推动智能设备的供电方式发生重大变化，以更有效地从建筑物内的照明中收集广泛可用的能源。这种能源可以通过室内光伏（IPV）进行可再生收集，这对于为推动第四次工业革命的数十亿自主智能设备提供动力非常有吸引力。然而，行业标准 IPV（氢化非晶硅；a-Si:H）的效率仅为 20% 左右，大多数商业设备的效率<10%。HERALD 将从新型红铜矿和硫卤化物中开发 IPV，这些产品具有潜力在室内照明下达到 >48% 的效率。这些是基于产烟剂铋和锑的低毒、高稳定性材料，它们在室内光收集方面的巨大潜力刚刚开始显现。 HERALD 将使用从宏观到近原子尺度的分层表征方法将这些新型化合物转化为领先的 IPV。在此过程中，我们将获得基本的了解，以了解性能限制因素是什么以及如何系统地缓解这些因素。终点将是高性能、耐用且对环境影响较小的测试设备。这些材料将使用新型等离子喷涂技术快速大规模生长，并且IPV将在商业智能设备中原型化。开发的基于pnictogen的IPV可以通过减少智能设备对仅由电池供电的依赖来对智能设备产生变革性影响，需要定期更换，造成大量浪费。新的IPV可以在不损害环境的情况下部署，并且将比a-Si:H IPV获得更多的电力，以支持具有更先进功能的智能设备。基于磷元素的半导体的开创性发展也将推动它们在众多光伏领域的发展，从清洁太阳能燃料生产到医学成像辐射检测。
