Flexible Triple Junction GaAs Epitaxial Wafer / Solar Cell 3.1 Product Name: 32% Efficiency, 4 inch Flexible 3J GaAs Epitaxial Wafer / Solar Cell Applications: Power systems for spacecraft across multiple orbits, deep space exploration missions, space stations, and solar array skins for near-space solar-powered UAVs. Description: Our flexible 32% space solar cell adopts a GaInP/GaAs/InGaAs triple-junction structure. It employs inverted metamorphic epitaxial growth with advanced MOCVD, where the subcells are connected by tunnel junctions in an inverted stacking sequence, to improve current matching and reduce thermal loss. Substrate transfer technology relocates the epitaxial layers onto a flexible metallic substrate, resulting in a lightweight, bendable, and highly efficient solar cell.
