项目摘要

This proposal is aimed at developing a new solar cell or photovoltaic (PV) technology based on III-V semiconductor nanowires. The highest solar cell efficiencies achieved thus far use III-V semiconductor materials such as gallium arsenide, where research-grade solar cells have exceeded 40% efficiency under concentrated sunlight. These devices employ highly perfect semiconductor thin films in a multi-junction device structure, which consists of sub-cells connected electrically in series. However, these cells are not optimized due to the need to use materials of similar crystal lattice to avoid the generation of defects in the films that would otherwise reduce efficiency. Furthermore, the existing thin film technology is prohibitively expensive due to the materials used such as germanium. To overcome these limitations, this proposal proposes a two-junction cell comprised of nanowires on relatively inexpensive substrates such as silicon. The main advantage of nanowires is the greater freedom to combine materials of different crystal structure to optimize solar cell efficiency. As a result, a nanowire-based solar cell should have optimum efficiency that is comparable to that of commercial thin film cells (>40%), while the former would significantly reduce cost by using cheaper substrates. The efficiency of a nanowire PV device is greatest when the nanowire diameter, length, and spacing are optimized as shown by our recent theoretical work. Therefore, the main focus of this proposal will be the development of ordered nanowire arrays. Scientifically, this proposal will provide key aspects in the design of nanowire-based devices. The proof-of-principle devices produced by this proposal will catalyze a significant worldwide increase within the area of nanostructured III-V/Si solar cells, an area where Canada will then be a leading contender.
该提案旨在开发基于III-V族半导体纳米线的新太阳能电池或光伏(PV)技术。迄今为止,使用砷化镓等III-V族半导体材料实现的最高太阳能电池效率,其中研究级太阳能电池在集中阳光下的效率超过40%。这些器件采用多结器件结构中的高度完美的半导体薄膜,其由串联电连接的子电池组成。 然而,由于需要使用类似晶格的材料以避免在膜中产生否则将降低效率的缺陷,因此这些电池未被优化。 此外,现有的薄膜技术由于使用诸如锗的材料而过于昂贵。 为了克服这些限制,该提议提出了一种由相对便宜的衬底(例如硅)上的纳米线组成的双结电池。纳米线的主要优点是可以更自由地联合收割机组合不同晶体结构的材料,以优化太阳能电池的效率。因此,基于锗的太阳能电池应该具有与商业薄膜电池相当的最佳效率(>40%),而前者将通过使用更便宜的基板来显著降低成本。我们最近的理论工作表明,当纳米线的直径、长度和间距得到优化时,纳米线光伏器件的效率最高。 因此,这项提案的主要重点将是有序纳米线阵列的发展。 从科学上讲,该提案将为基于硅的设备的设计提供关键方面。该提案所生产的原理验证设备将在纳米结构III-V/Si太阳能电池领域促进全球范围内的显着增长,加拿大将成为该领域的领先竞争者。
