Imagine a world where every window, glass facade, or even your smartphone screen not only serves its primary function but also generates electricity. South Korea is turning this vision into reality with its groundbreaking advancements in transparent solar technology. By integrating energy-harvesting capabilities into transparent surfaces, Korea is setting the stage for a sustainable future where design and functionality coexist harmoniously.
What is Korean Invisible Solar Technology?
Korean Invisible Solar Technology refers to the development and implementation of transparent or near-invisible solar panels by South Korean companies and researchers. These panels are designed to generate electricity while remaining see-through, making them ideal for applications where aesthetics and natural lighting are crucial—like windows, glass buildings, and mobile devices.

Key Innovations and Companies in Korea
1. Ubiquitous Energy Korea
In collaboration with U.S.-based Ubiquitous Energy, this venture focuses on developing fully transparent solar coatings. These coatings can be applied to windows, allowing them to generate electricity without obstructing the view. The technology is particularly suited for smart windows in office buildings and consumer electronics.
2. LG Electronics and LG Chem
LG is exploring perovskite-based solar films with partial transparency. Their focus is on integrating these films into glass panels and rooftops for both commercial and residential buildings, aiming to combine energy efficiency with aesthetic appeal.
3. Korea Institute of Energy Research (KIER)
KIER has developed semi-transparent perovskite solar cells achieving over 21% efficiency. These cells maintain high transparency while generating substantial electricity, making them suitable for building-integrated photovoltaics (BIPV).
Applications of Transparent Solar Technology
1. Smart Windows
Transparent solar panels can be integrated into windows, allowing buildings to generate electricity while maintaining natural lighting. This application is particularly beneficial for skyscrapers and urban buildings where space for traditional solar panels is limited.
2. Greenhouses
In agricultural settings, transparent solar panels can be used in greenhouses to generate electricity without compromising the light needed for plant growth. This dual functionality supports sustainable farming practices.
3. Mobile Devices
The technology can be applied to the screens of smartphones and tablets, enabling them to charge through ambient light exposure, thus extending battery life and reducing reliance on external power sources.
4. Automotive Glass
Car sunroofs and windows equipped with transparent solar panels can generate electricity to power vehicle systems, contributing to the development of more sustainable automotive technologies.
