Abstract

We present a new design of high sensitivity, multi-spectral capability AlGaAsSb/InGaAsSb phototransistors for infrared sensing and solar energy conversion applications. These devices are grown by molecular beam epitaxy (MBE), which exhibit high responsivity at room-temperature. The 50% cutoff wavelength of spectral photoresponse is 2.2 μm. Similar structures are also investigated for solar cell applications. The possibility of increasing the solar energy conversion is explored by incorporating nano-antenna array into the solar cell. The broad-band nano-antenna is designed using Ansoft HFSS. The results indicate high solar energy conversion can be achieved for highly efficiency, flexible, lightweight solar power generations for the applications such as aircraft, airbase and special operations.
