Hybrid III-V optoelectronic devices nano-fabrication: application to concentrated photovoltaics

在2016年和未来十年，效率超过50%的太阳能电池有很大的潜力，以进一步发展人们的能源获取，同时减少我们对化石燃料和二氧化碳排放的严重依赖。然而，在超过高浓度CPV的50%效率的实验室记录与在真实的世界中具有成本效益和工业兼容方法的等同成就之间存在巨大差异。* 通过这项研究计划，我们将致力于为50%的电池效率铺平道路，同时开发CPV器件技术，尽可能多地借鉴其他工业领域现有的技术，如用于3D集成的微电子和先进的低成本封装，以及已知的如何从LED行业中获得非常低成本的GaN基高带隙能量材料的大批量生产。* 由于在光电子器件方面拥有20年的专业知识，包括III-V激光二极管，基于锗的CPV和基于GaN的光电子器件的III-V，该计划的独创性将是开发器件级概念，并从工业化的角度强调最终产品特性，作为实验设计的一部分。这将涉及锗/III-V异质结构与GaN/InGaN器件的混合集成，以及关键的混合集成/封装和热管理开发，为该领域开发此类架构开辟道路，产生最有效的太阳能光伏能源。Universite de Sherbrooke独特的纳米纤维基础设施和基于CNRS国际联合单位“Nanotechnologies Nanosystèmes（UMI-3463 LN 2）”的非常强大的国际合作网络对于该研究计划的成功至关重要。这也将使我们能够获得最先进的材料Ge/III-V和GaN/InGaN，这对这项研究计划至关重要。该项目的协作环境融合了卓越的研究和工业专业知识的独特组合，并将开辟以具有成本效益的方法记录高效率系统的道路。利用USherbrooke太阳能试验场，我们还将开发专用于现场测试的测试车辆，使用现成的CPV电池技术和混合动力设备来验证我们的设计。最后，作为该研究计划的一部分，未来5年将开发的各种创新当然将有利于CPV部门，但也会影响周围的工业部门，包括LED照明行业和微电子/光电子未来集成电路，这些集成电路将在未来十年内装备大多数高性能计算机。从而提供独特的技能，以高素质的个人通过该计划的培训，并反过来提供人才资源，为加拿大产业的利益。

In 2016 and for the next decade, there is a lot of potential for beyond 50% efficiency solar cells in order to further develop energy access to the people while reducing our strong dependence on fossil fuels and CO2 emissions.***However, there is a vast difference between a laboratory record beyond high concentration CPV at 50% efficiencies and an equivalent achievement in the real word with a cost-effective and industrially compatible process. ****With this research program, we will work intensely on paving the road to 50% cell efficiencies while developing CPV device technologies inspired as much as possible from existing technological bricks available in other industrial sectors such as microelectronics for 3D integration and advanced low-cost packaging as well as know-how from the LED industry for very large volume production at very low cost for GaN based high bandgap energy materials. ****Thanks to 20 year expertise on optoelectronics devices, both III-V laser diodes, III-V on Germanium based CPV and GaN based optoelectronics, the originality of this program will be to develop device level concepts with a strong emphasis on the final product characteristics from the industrialization point of view as part of the Design of Experiments. This will involve hybrid integration of Germanium/III--V heterostructures with GaN/InGaN devices and key hybrid integration/packaging and thermal management developments to open the way to the development of such architectures in the field, producing the most efficient solar Photovoltaics energy.***Universite de Sherbrooke unique nanofabrication infrastructures and a very strong international collaborative network based on the CNRS international joint unit "Laboratoire Nanotechnologies Nanosystèmes (UMI--3463 LN2)" will be essential for the success of this research program. This will also give us access to state of the art materials both Ge/III-V and GaN/InGaN that will be essential for this research program. The collaborative environment for this project blends a unique mix of excellence in research and industrial expertise and will open the way to record high efficiency systems with a cost-effective approach. Using the USherbrooke solar test site, we will also develop test vehicules dedicated to on-site testing with both off the shelve CPV cell technologies and hybrid devices to validate our designs.***Finally, as part of this research program, the various innovations that will be developed over the next 5 years will of course benefit to the CPV sector but also impact the surrounding industrial sectors including LED lighting industry and microelectronics/optoelectronics future integrated circuits who will equip most high performance computers over the next decade, thus offering unique skillsets to highly qualified personal trained through this program and in turn provide talented resources for the benefit of the Canadian industry.
