Photonic power is emerging as a driver of next-generation energy systems, where R&D and uptake must accelerate to avoid the severest impacts of climate change, forming a new global clean energy economy critically coupled to higher efficiency, electrification, digitalization, and sustainability. Photovoltaic (PV) solar power is now the least expensive new electricity generator in many regions worldwide, transforming energy industries from global polluters into clean local providers. PV innovations can also be harnessed synergistically in very different applications in aerospace, health, and telecoms. This research program seeks breakthroughs in two photovoltaic themes: (1) PV materials & devices, and (2) system strategies & resource assessments. Research on versatile compound semiconductor (III-V) materials and devices identifies better efficiencies for multijunction solar cells, photonic power converters, and thermal photovoltaics (TPV). For systems, better solar field performance forecasting de-risks business buildout strategies for bifacial systems and structure-integrated photovoltaics, and novel photonic power converter systems revolutionize power and data transmission in free space or over optical fibre. This proposal grows our science capabilities in new directions: (a) accelerating accurate design of better multijunction III-V devices by grafting artificial intelligence (AI) techniques for complex optimizations onto standard numerical engines for solid-state physics; (b) novel ultrathin, textured multijunction architectures for PV devices; (c) new fabrication and epitaxy techniques for PV and TPV devices; (d) novel models for PV collection and conversion; and (e) green hydrogen production from water, powered by solar cells matched precisely to electrolyzer voltages. Program impact is foremost to accelerate transition programs to clean energy economies in Canada and worldwide, ramping faster cost reductions and efficiency improvements in campaigns mitigating fuel consumption, emissions, and waste. For example, each percentage point improvement in solar panel efficiency is equivalent to a proportionate cost reduction of the entire field and distribution network, not just the panels. Lightweight optical fibre systems moving power and data around aerospace vehicles will replace heavy copper cable bundles, reducing parts count and simplifying builds. TPV devices scavenge waste heat from industrial plants or propulsion engines, generating local electrical power. A program hallmark is to exploit similar materials science and device physics across many different applications and markets. The program will train four PhD students and two undergraduate students per year in leading-edge technologies, providing a grounding in semiconductor photonics design, fabrication, and performance testing, applied across renewable energy systems and information and communications products and services in Canadian and global markets.

光子功率正在成为下一代能源系统的驱动力，在该系统中，研发和吸收必须加速以避免气候变化的最严重影响，形成了一种新的全球清洁能源经济，并与更高效率，电气化，数字化和可持续性结合起来。光伏（PV）太阳能现在是全球许多地区最便宜的新电力发生器，将能源行业从全球污染者转变为清洁的本地提供商。在航空航天，健康和电信的截然不同的应用中，PV创新也可以协同利用。该研究计划寻求两个光伏主题的突破：（1）PV材料和设备，以及（2）系统策略和资源评估。多功能化合物半导体（III-V）材料和设备的研究确定了对多期太阳能电池，光子功率转换器和热光伏（TPV）的更好效率。对于系统，更好的太阳能田间性能预测降级风险的双面系统和结构融合光伏的业务建立策略，新型的光子电源转换器系统彻底改变了自由空间或光纤上的功率和数据传输。该建议在新方向上发展了我们的科学能力：（a）通过接管人工智能（AI）技术来加速更好的多式iii-V设备的精确设计，以在固态物理的标准数值发动机上进行复杂的优化； （b）新颖的超薄，纹理的多式式体系结构，用于光伏设备； （c）PV和TPV设备的新制造和外延技术； （d）PV收集和转换的新型模型； （e）由水生产的绿色氢，由太阳能电池驱动，与电解室电压完全匹配。计划的影响是加速到加拿大和全球清洁能源经济体的过渡计划，从而提高成本降低的速度和效率提高，以减轻燃油消耗，排放和废物的效率。例如，太阳能电池板效率的每个百分比提高等同于整个领域和分销网络的成本降低，而不仅仅是面板。轻巧的光纤系统移动电源和航空航天车辆周围的数据将取代重型铜线束，减少零件数量并简化构建。 TPV设备清除工厂或推进发动机的废物，从而产生当地电力。计划标志是在许多不同的应用和市场上利用类似的材料科学和设备物理。该计划将每年培训四名博士学位学生和两名本科生的领先技术，从而在加拿大和全球市场的可再生能源系统以及信息系统以及信息和通信产品和服务上应用半导体光子学设计，制造和绩效测试。
