Icomponent Supplies 'Barrier Film Samples for Space Solar Cells' to Leading Global Space Companies

icomponent will supply barrier film samples for space solar cells to leading global companies in the space industry.

According to icomponent on September 17, the supplied samples are multilayer barrier films for space solar cells, developed for application in space environments. Based on existing barrier film technology for terrestrial use, the company has added functions to protect solar cells in the harsh space environment, including extreme temperature fluctuations, atomic oxygen (AO), ultraviolet rays (UV), and radiation. The company plans to continuously improve product performance by reflecting customer evaluations in the future.

Currently, gallium arsenide compound-based solar cells are mainly used in space solar cells. However, the high manufacturing costs limit their large-scale application. As a result, flexible perovskite solar cells—with lightweight and flexible structures that reduce weight and volume while providing high efficiency—are emerging as a next-generation candidate for space solar cells.

icomponent plans to proactively develop barrier films for space solar cells from the early stage of market formation, following its success in terrestrial solar cell barrier films, to foster new growth engines for the future. Since multilayer barrier films can be applied to various solar cell materials, the company aims to target the space solar cell market by developing and supplying products tailored to the needs of client companies.

A representative from icomponent stated, “We have established a roadmap for developing products suitable for space environments, based on our existing technology for perovskite solar cell barrier films for terrestrial use, and we are actively responding to the relevant market. Through testing with global clients, we will enhance product completeness, secure patents, and advance our technology to proactively address the early-stage space solar cell market.”
