Microquanta launches 26%-efficient colored perovskite-silicon tandem modules for building-integrated PV

Chinese perovskite solar specialist Microquanta has unveiled this week a new perovskite silicon tandem solar module for building-integrated PV (BIPV) applications at the Smarter E event in Munich, Germany.

“We developed the new colored tandem modules as part of a broader push into the BIPV market,” a spokesperson from the company told pv magazine. “The product combines the company’s four-terminal perovskite-silicon tandem technology with customizable colored finishes aimed at façade applications.”

According to the manufacturer, the tandem architecture helps offset the power losses typically associated with colored solar modules, enabling higher energy yields than conventional decorative BIPV products. “Unlike many BIPV suppliers that rely on externally sourced colored glass, Microquanta performs the coloring process in-house, allowing it to tailor colors and finishes to architects’ specifications,” the spokesperson went on to say. “We are initially showcasing a marble-effect design but the technology can be adapted to a wide range of colors and appearances. The current product uses TOPCon silicon cells in a four-terminal configuration, although the architecture is compatible with other silicon technologies.”

Microquanta describes the module as a fully commercial product rather than a prototype and says it is already in discussions with developers for future projects. While the modules are expected to cost more than conventional single-junction BIPV products, the company believes they remain competitive within the premium BIPV segment, where aesthetics, customization, and building integration are often more important considerations than module price alone.

The 26%-efficient MQ-α² tandem module series offers a power range from 65 W to 165 W. Microquanta backs the product with a 25-year linear power output warranty and a 12-year product and workmanship warranty. The company specifies an initial-year degradation rate of 2%, followed by annual degradation of 0.7%, resulting in a guaranteed 80% of original output after 25 years.

From a mechanical perspective, the modules are rated for front and rear static loads of 2,400 Pa and have passed hail resistance testing with 25 mm hailstones at velocities of 23 m/s. The products are designed for systems operating at up to 1,500 V and carry a rated current of 15 A.

The spokesperson highlighted the product’s suitability for customized projects, with module dimensions, electrical characteristics, and aesthetic finishes available on a make-to-order basis.

The company, headquartered in Hangzhou, China, is among the early commercial developers of perovskite photovoltaic technology. In January 2025, its 810cm² perovskite module achieved a 21.86% efficiency certification from China’s National PV Industry Measurement and Testing Center. The company is currently constructing a gigawatt-scale perovskite production line in Quzhou, Zhejiang province, aiming for mass production.
