Panasonic in Numbers: Perovskite Solar Cells

Imagine living or working in a building where nearly every exterior surface can generate renewable energy. Panasonic’s Perovskite solar cells* are produced using inkjet printing, allowing greater flexibility in terms of size and design, making it possible to expand solar power generation in ways that currently do not exist with traditional silicon-based solar cells. Perovskite cells also do not require high heat treatment and can be produced with much less energy than silicon-based solar cells, making them cheaper and more sustainable. In 2023, Panasonic achieved an energy conversion efficiency of 18.1% with an 804cm2 Perovskite solar cell, the world’s highest level of power generation efficiency in a practical size** module. Panasonic is now conducting a demonstration test of a prototype for building-integrated Perovskite photovoltaics glass at Fujisawa Sustainable Smart Town in Kanagawa Prefecture, Japan.

* Panasonic Perovskite solar cells are a development phase technology currently undergoing outdoor demonstration testing to confirm power generation performance and durability. Commercialization is expected within a few years.
** Practical size: refers to an effective area of power generation of 800 cm2 or larger.
