Flexell Space is developing a portfolio of advanced CIGS/Perovskite tandem space solar technologies to deliver high-efficiency and cost-effective power solutions for satellites and future space infrastructure. Designed to overcome the limitations of conventional III-V space solar cells, the company's solutions focus on reducing launch mass, shortening production lead times, lowering manufacturing costs and providing greater design flexibility for the rapidly expanding New Space industry.

Its satellite product portfolio includes BLUESHELL, BLUETACK and BLUESAIL, each designed for different spacecraft integration requirements. BLUESHELL is a rigid Plug & Play solar solution that allows satellite manufacturers to integrate advanced solar technology into existing spacecraft designs with minimal modification. BLUETACK is a lightweight Stick & Peel product that uses a flexible polyimide substrate, enabling solar cells to conform to curved spacecraft structures and compact satellite platforms. For satellites requiring higher onboard power, BLUESAIL combines flexible tandem solar cells with deployable array technology to provide customer-optimised power generation while minimising launch volume.

These products are powered by Flexell's proprietary CIGS/Perovskite tandem solar cell technology, which is designed to achieve 28–30% conversion efficiency while reducing system weight by more than 90% and manufacturing costs by over 60% compared with conventional III-V space solar cells. The technology supports large-area solar cells up to 20 × 20 cm, incorporates radiation-resistant and self-healing thin-film characteristics for long-duration missions, and is supported by a planned 15 MW annual production capacity to meet increasing demand from the satellite industry.

Flexell's products are designed to support a wide range of satellite applications, from CubeSats and small satellites to larger spacecraft requiring deployable power systems. The lightweight construction of BLUESHELL, BLUETACK and BLUESAIL helps increase available payload capacity while reducing launch costs, making them suitable for Earth observation, communications, scientific and other commercial satellite missions. Their flexible and deployable architectures also provide greater design freedom for next-generation satellite platforms.

Beyond conventional satellites, Flexell is extending its technology to space exploration, Space-Based Solar Power (SBSP), and High-Altitude Pseudo Satellites (HAPS). The company's solar solutions are designed to power lunar and planetary rovers, space shelters, and future orbital infrastructure, while deployable solar modules support concepts for harvesting solar energy in orbit for wireless power transmission. The lightweight, high power-to-weight characteristics of the technology also make it suitable for HAPS supporting communications, surveillance and Earth observation. In addition, Flexell is exploring terrestrial applications across air mobility, ground mobility, marine mobility, concentrated photovoltaics (CPV) and building-integrated photovoltaics (BIPV), expanding the reach of its thin-film solar technology beyond the space sector.
