Value proposition

Provides a 100x thinner and significantly lighter power source than legacy silicon or III-V solar cells, offering 32% higher efficiency and 15-year orbital durability without the need for heavy protective coverings.

Products and solutions

Flexible TMD (Transition Metal Dichalcogenide) Solar Modules, Radiation-Hardened Satellite Power Skins, AI-Optimized Semiconductor Material Designs, Deployable/Rollable Space Solar Arrays

Unique value

Utilizes 2D Transition Metal Dichalcogenides (TMDs) which are atoms-thick materials that maintain high efficiency and extreme radiation resistance without the weight of traditional glass shielding.

Target customer

Satellite manufacturers, commercial space station operators, space agencies (NASA/ESA), and developers of lunar/interplanetary missions.

Industries served

Aerospace & Space Technology, Renewable Energy, Deep Tech, Specialized Electronics (IoT & Wearables)

Technology advantage

Achieves a market-leading power-to-weight ratio (specific power) and utilizes AI-driven material discovery to optimize semiconductor layers for extreme orbital environments.

How they differentiate

Utilizes 2D Transition Metal Dichalcogenides (TMDs) to create solar cells that are 100x thinner than traditional silicon, inherently radiation-hardened without heavy glass shielding, and capable of being applied as a flexible 'skin' to spacecraft.

Main competitors

Solestial, mPower Technology, Spectrolab (Boeing)

Key partnerships

Breakthrough Energy (Fellowship Cohort 4), Stanford University (TomKat Center for Sustainable Energy & HIT Fund), Space Capital, SpaceCadet Ventures

Notable customers

NASA (Research/Grant partner), Satellite OEMs (Confidential)

Major milestones

Selected for Breakthrough Energy Fellows Cohort 4 (2024), Recipient of the Stanford HIT Fund and TomKat Innovation Transfer Award, Closed $4M Seed round led by Space Capital (Dec 2024), Demonstrated 2D material solar cells with 32% higher efficiency in lab settings

Growth metrics

Transitioned from Stanford University research to venture-backed startup; aiming for megawatt-scale production by 2028.

Market positioning

Deep-tech 'New Space' infrastructure provider focusing on high-specific-power (watts per kilogram) energy solutions.

Geographic focus

North America (Palo Alto, CA), targeting global commercial satellite constellations and lunar exploration missions.

Patents and IP

Proprietary technology developed through Stanford University's Pop Lab and Bent Research Group; includes IP related to 'Direct ALD of amorphous MoS2 thin films' for extraterrestrial applications.
