Power-Generating Windows: Panasonic's Perovskite Solar Cells

  • Panasonic's new power-generating window harnesses perovskite solar cells for a conversion efficacy of 17.9%. Learn how the see-through module utilizes inkjet printing and a horizontal stripe pattern to generate hundreds of millions of dollars.

Panasonic has recently developed a new type of power-generating window using perovskite solar cells. The module has a conversion efficacy of 17.9%, which is the second highest worldwide for a perovskite cell larger than 800 sq. centimeters. The tech behind the power-generating glass relies on inkjet printing technology that permits the material to be applied uniformly on a glass exterior. The challenge in creating the tech to still allow the glass to be see-through is overcome with a horizontal stripe pattern. Panasonic expects this new technology to generate hundreds of millions of dollars and may expand to working with construction companies to employ this new tech as a building material.

What Are the Benefits of Panasonic's Power-Generating Windows?

  • Solar cells made with perovskite have the highest energy conversion efficiencies to date
  • Panasonic's power-generating window has a conversion efficacy of 17.9%, second highest worldwide for a perovskite cell larger than 800 sq. centimeters
  • Inkjet printing technology allows the material to be applied uniformly on a glass exterior without obstructing the view
  • Horizontal stripe pattern allows for transparency while still creating a power-generating window
  • Can be used for construction materials, creating a new revenue stream for Panasonic
  • Can save energy costs for commercial and residential buildings and reduce reliance on non-renewable energy sources
  • Offers a sustainable and renewable energy solution for buildings
