en.Wedoany.com Reported - Flexell Space is developing a series of CIGS/perovskite tandem space solar technologies, aiming to provide efficient and cost-effective power solutions for satellites and future space infrastructure. The products launched by the company are designed to overcome the limitations of traditional III-V space solar cells, with a focus on reducing launch mass, shortening production cycles, lowering manufacturing costs, and offering greater design flexibility for the rapidly expanding new space industry.
Flexell Space's satellite product portfolio includes BLUESHELL, BLUETACK, and BLUESAIL, each designed for different spacecraft integration needs. BLUESHELL is a rigid plug-and-play solar solution that enables satellite manufacturers to integrate advanced solar technology into existing spacecraft designs with minimal modifications. BLUETACK is a lightweight peel-and-stick product using a flexible polyimide substrate, allowing 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, offering customer-optimized power generation while minimizing launch volume.
These products are powered by Flexell's proprietary CIGS/perovskite tandem solar cell technology. This technology aims to achieve a conversion efficiency of 28–30%, while reducing system weight by over 90% and manufacturing costs by over 60% compared to traditional III-V space solar cells. The technology supports large-area solar cells up to 20 × 20 cm, featuring radiation-resistant and self-healing thin-film properties suitable for long-term missions. Flexell plans to build a production capacity of 15 MW per year to meet the growing demand from the satellite industry.
Flexell's product design supports a wide range of satellite applications, covering everything from CubeSats and small satellites to large spacecraft requiring deployable power systems. The lightweight structure of BLUESHELL, BLUETACK, and BLUESAIL helps increase payload capacity while reducing launch costs, making them suitable for Earth observation, communications, scientific, and other commercial satellite missions. Their flexible and deployable architecture also provides greater design freedom for next-generation satellite platforms.
Beyond conventional satellites, Flexell is expanding its technology into areas such as 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 habitats, and future orbital infrastructure, while deployable solar modules support the concept of collecting solar energy in orbit for wireless power transmission. The technology's lightweight, high power-to-weight ratio also makes it suitable for supporting high-altitude pseudo-satellites (HAPS) for communications, surveillance, and Earth observation. Additionally, Flexell is exploring terrestrial applications such as aerial mobility, ground mobility, marine mobility, concentrator photovoltaics (CPV), and building-integrated photovoltaics (BIPV), extending the use of its thin-film solar technology beyond the space sector.
