Morgan Solar Inc. (MSI) is a Canadian company specialized in solar energy. They have invented an entirely new approach to the design and manufacture of solar concentrated photovoltaic (CPV) modules. Their low cost CPV technology is a market-disruptive product which is making solar energy less expensive. Their flagship product is the Sun SimbaTM CPV panel. The main component consists of a patented Light-guide Solar Optic (LSO), an ultra-thin solar concentrator, where sun light is guided using total internal reflection to be concentrated above 800x on high performance multi-junction solar cells (MJSCs). These MJSC cells convert over 40% of the sunlight into electricity. One strategy to reduce the overall system cost is to reduce the size of the CPV system, i.e. smaller lenses and MJSCs. The ability to reduce MJSC size to below 1 mm2 facilitates an increase in nominal module efficiency, from 29% to approximately 35% absolute. Shrinking cell sizes in the mm range and below is getting unpractical for industrial fabrication processes used in CPV cell production of larger sizes. Therefore innovative wafer scale approches to fabricate such small cells in a cost effective approach will be developed, specific device improvements will also be studied through III-V device material passivation.

摩根太阳能公司(MSI)是一家专门从事太阳能的加拿大公司。他们发明了一种完全 太阳能聚光光伏（CPV）模块的设计和制造的新方法。它们的低成本 CPV技术是一种市场颠覆性产品，它使太阳能变得更便宜。他们的旗舰 产品是Sun SimbaTM CPV面板。主要组件包括一个专利的光导太阳能光学 (LSO)超薄太阳能集中器，其中太阳光利用全内反射被引导， 在高性能多结太阳能电池（MJSC）上，这些MJSC细胞转化为 超过40%的太阳能转化为电能。 降低整体系统成本的一个策略是减小CPV系统的尺寸，即，更小的透镜， MJSC。将MJSC尺寸减小到1 mm 2以下的能力有助于提高标称模块效率， 从29%上升到35% 将单元尺寸缩小到mm范围和更小对于所使用的工业制造工艺变得不切实际。 在较大尺寸的CPV细胞生产中。因此，创新的晶圆级方法来制造这种小电池 在一个具有成本效益的方法中，还将通过III-V研究具体的器件改进 器件材料钝化。
