Abstract

A commercial lattice-matched InGaP/InGaAs/Ge solar cell has reached an average efficiency of 40% at 500 kW/m2. The design changes that lead to this result are discussed. These data are complemented with a presentation of the latest new solar cell development results from the laboratory. Inverted metamorphic multijunction solar cells have been prototyped with 42.4% efficiency at 325 suns for concentrator applications and 33.6% efficiency at 1 sun AM0 for space applications. Six subcell devices are now under development. These results are used, along with other experimental data and other industrial constraints, as input to a computer model to predict what practical efficiency might be achievable with this device approach. The computer model suggests that 45% and 50% efficiencies are technologically feasible with a three-junction and five-junction device, respectively, at an irradiance of 500 kW/m2 and 25 °C using known materials, device architectures, and manufacturing methods.
点阵匹配的太阳能电池在试点生产中平均效率为40%,路线图为50%
商用晶格匹配的InGaP/InGaAs/Ge太阳能电池在500kw /m2时达到了40%的平均效率。讨论了导致这一结果的设计变更。这些数据与实验室最新的新型太阳能电池开发结果的介绍相辅相成。倒置变质多结太阳能电池的原型在325个太阳下的效率为42.4%,在1个太阳AM0的空间应用中效率为33.6%。目前正在开发六种亚单元装置。这些结果与其他实验数据和其他工业限制一起被用作计算机模型的输入,以预测这种设备方法可能实现的实际效率。计算机模型表明,使用已知材料、器件架构和制造方法,在500 kW/m2和25°C的辐照度下,三结和五结器件的效率分别为45%和50%,在技术上是可行的。
