Sharp Introduces Space-Ready Solar Cells, Eyes Perovskite-Silicon Tandem Line

Sharp’s Space-Grade Solar Innovation

The Japanese technology manufacturer Sharp has unveiled three types of space-qualified compound solar cell designs intended for satellites and other spacecraft. These advanced cells are engineered to deliver high conversion efficiency and reliability under extreme conditions found beyond the Earth’s atmosphere.

Product Details

Sharp’s lineup includes:

Each model is designed to withstand mechanical vibration, radiation exposure, and temperature variations encountered during rocket launches and in orbit.

Perovskite-Silicon Tandem Plans

In addition to its space applications, Sharp is preparing for industrial-scale production of perovskite-silicon tandem solar cells. These high-efficiency, next-generation devices combine perovskite’s absorption strength with the proven durability of silicon, aiming to surpass current photovoltaic performance standards.

Industry Outlook

Sharp’s move reinforces its position in the high-efficiency solar technology sector, as competition in both terrestrial and space solar markets intensifies. The company’s expansion into tandem production reflects a strategic shift toward sustainable and advanced photovoltaic development.

“We see tandem technology as the next major leap that merges innovation from space and Earth-based solar applications,” the company noted.

Author summary:
Sharp launches three space-grade solar cell types and prepares to mass-produce perovskite-silicon tandem modules, marking a milestone in high-efficiency photovoltaic development.
