Microlink Devices

What Microlink Devices does

MicroLink Devices is a privately held U.S. semiconductor and photovoltaic company founded in 2000 by Dr. Noren Pan and headquartered in Niles, Illinois, operating from a 30,000 sq-ft facility that includes a 3,000 sq-ft class-1000 clean room. The company designs and manufactures III-V compound semiconductor devices — primarily GaAs-based — built around two technology pillars: (1) Metal Organic Chemical Vapor Deposition (MOCVD) epitaxy of GaAs and InP materials, and (2) a proprietary Epitaxial Lift-Off (ELO) process that releases thin-film multi-junction solar cells from their growth substrate so the substrate can be reused, with an exclusive license from NREL for inverted metamorphic multi-junction (IMM) device architectures. This stack has produced NREL-certified 37.75% power conversion efficiency on 6-inch GaAs and >3,000 W/kg specific power under AM0 — described as world records for triple-junction ELO solar cells.

The product portfolio spans high-efficiency ELO solar cells and flexible solar sheets for UAVs, HALE platforms, satellites, and concentrated photovoltaic (CPV) applications; InGaP and BiFET epitaxial wafers for heterojunction bipolar transistors (HBTs) and power amplifiers used in high-volume cellular phones (cumulative install base exceeding 100 million phones); and contract engineering services. MicroLink has been a prime U.S. federal contractor on more than 30 programs since 2003 for NASA, DARPA, AFRL, NRL, NREL, and NSF, and was recognized by Airbus Defence and Space as a key supplier for the Zephyr HAPS UAV in October 2019 following its first production solar array contract with Prismatic Ltd. for the PHASA-35.

The business model combines custom hardware sales (solar cells/sheets and RF epitaxial wafers, quote-based pricing on multi-year contracts) with professional services revenue from federal R&D contracts. Go-to-market is enterprise field sales led by a VP of Business Development, targeting a small set of aerospace primes (Airbus, Prismatic), major wireless phone OEMs, and U.S. government agencies. The company has been ISO 9001 certified since 2005, is founder-controlled, and has no disclosed external funding, M&A activity, or institutional investors.

Core offering

MicroLink Devices designs and manufactures high-efficiency GaAs-based solar cells and solar sheets for UAVs, spacecraft, and terrestrial applications using proprietary Epitaxial Lift-Off (ELO) technology. The company also produces InGaP and BiFET epitaxial wafers for heterojunction bipolar transistors (HBTs) and power amplifiers used in high-volume cellular and WLAN applications. Engineering services for custom solar cell and RF device development round out the offering, with the company serving as a U.S. federal prime contractor since 2003.

Product overview

MicroLink Devices offers a portfolio of semiconductor and photovoltaic products centered on III-V epitaxial materials and epitaxial lift-off (ELO) technology. The product line includes UAV Solar Cells (single, dual, and triple-junction variants with up to 31% efficiency), Space Solar Cells (triple-junction IMM cells at 29% efficiency), Solar Sheets for UAVs (>30% efficiency), and CPV Solar Cells for concentrated photovoltaic applications. Complementary RF Semiconductor Materials include InGaP Epitaxial Wafers (for HBTs used in cellular phones) and BiFET Epitaxial Wafers (for power amplifiers and switches), with material used in over 100 million mobile phones. Engineering Services support custom RF device structure development and contract R&D for government agencies. All photovoltaic products leverage the proprietary Epitaxial Lift-Off (ELO) technology platform, which enables thin, flexible, lightweight solar cells while allowing GaAs substrate reuse to reduce costs.
