CHALLENGES

Space solar cells need to be improved in

the cost, delivery, design and power


High Cost

  

High costs of materials such as

germanium, rare earths


Long Delivery

  

Insufficient supply falling

to keep up with demand


Design Constraints

  

Satellite manufacturing

constraints due to SWaP


Low Power

  

Additional features can’t be equipped 

due to insufficient power

QUICK FACTS


01

  

Low Cost

 

Low material cost and

optimized production lines 

60% or more cost savings 


02

 

High Efficiency 

 

CIGS/Perovskite tandem allows the

same level of efficiency as III-V cells

28~30%


03

  

Durable/Flexible

 

Durable & flexible thin film

substrate is applied

Over 90% weight reduction


04

 

Customization

  

Deployment modules to meet

the customer’s mission requirements

Customer-optimized modules

KEY TECHNOLOGY 

Radiation resistance and self-curing capabilities to maintain performance until EOLEnd-of-Life 

Radiation-resistant

compound semiconductor

Self-curing characteristics

as thin-film solar cells

Maximizing space with 

a versatile cell shape

VALUE PROPOSITION

New solar cells designed for New Space Age

APPLICATIONS 

Our cutting-edge technology, driving innovative

achievements in satellites, rovers, shelters, 

is gaining attention across space fields. 

From cubesats to large satellites, our technology provides customers with high power and low cost of manufacturing and operation. 

Providing a reliable power source for space rovers and shelters that are exposed to harsh environments.

Generates high power through our infinite level of deployment module, and can be used safely in collisions with space debris.
