III-V Nanowire Solar Cells

Nano-Optoelectronic Materials and Devices
Single (left) and multi-junction (right) solar cells using InGaN/GaN nanowire heterostructures

 

We are developing single- and multi-junction InGaN nanowire solar cells on a Si platform. Nanowires will be grown directly on Si substrates under nitrogen rich conditions by MBE. By varying the indium and gallium compositions in the nanowire, the nanowire bandgap, or the absorption spectra, can be optimized to achieve solar cells with improved efficiency.
