High‐Efficiency Solar Cells Grown on Spalled Germanium for Substrate Reuse without Polishing Open
Radical reduction of III–V device costs requires a multifaceted approach attacking both growth and substrate costs. Implementing device removal and substrate reuse provides an opportunity for substrate cost reduction. Controlled spalling a…
(110)-Oriented GaAs Devices and Spalling as a Platform for Low-Cost III-V Photovoltaics Open
Here, we demonstrate the growth of GaAs solar cells by hydride vapor phase epitaxy (HVPE) on epi-ready and previously spalled (110) GaAs wafers as an advance towards a potentially low-cost (110)-based device platform. Controlled spalling o…
