Panasonic Corporation is a Japan-based worldwide leader in the development of diverse electronics technologies and solutions in the consumer electronics, housing, automotive, enterprise solutions and more.
Panasonic is focusing on the development of perovskite solar cells and takes part in various research activities like the Solliance program (as part of a research program concerning the development of roll-to-roll manufacturing processes aimed at large scale production of flexible perovskite solar cells where it will be one of the industrial partners), research work with EPFL, and more.
In March 2018, Panasonic and Sekisui Chemical announced the development of perovskite-based solar cells that can be attached to walls and curved surfaces.
In September 2023, it was reported that Panasonic is planning to sell windows made of “power-generating glass”, with perovskite solar cells integrated into transparent panes, to deliver power for homes.

Panasonic to present an artistic prototype based on perovskite solar cells at the Osaka Kansai Expo
Panasonic has announced it will exhibit an artistic prototype based on glass-type perovskite solar cells at the Panasonic Group Pavilion "Nomo no Kuni" at the 2025 World Expo in Japan (Osaka-Kansai Expo). For this Expo, Panasonic has collaborated with Heralbony, which has worked on many projects to decorate towns with artworks drawn by artists with disabilities, to express "Kaede no Scissors" by Wajima Kaede, a contracted artist of the company.

Panasonic's glass-type perovskite solar cells are characterized by their high degree of freedom in size, transparency, and drawing, achieved by combining unique material technology, inkjet coating methods, and laser processing technology. The company is currently developing the technology to commercialize the "power-generating glass". This prototype makes use of these features, broadening the scope of design expression using perovskite solar cells and demonstrating the possibility of creating a world where electricity is generated in a more natural way. This is the world's first case (according to Panasonic research as of February 14, 2025) where art has been expressed using perovskite solar cells.
Japan to launch public-private group to promote use of perovskite solar cells
Last week, it was reported that the Japanese government estimates the need for electricity output to rise 35% to 50% by 2050 due to growing demand from semiconductor plants and data centers backing artificial intelligence (AI). Now, Japan's industry ministry has said that it will launch a public-private group this month with the aim of commercializing perovskite solar cells, which are thin, light and bendable. The consortium will see 150 public and private entities, including local governments, working together to accelerate the adoption of flexible perovskite solar panels.
Perovskite solar cells, which can be installed flexibly in various places, such as on walls, are believed to hold the key to Japan's push for renewable energy. As the first step, the consortium will set a target for perovskite cell capacity by 2040. Current projections point to 38.8 GW, with the possibility of exceeding the capacity of conventional solar panels (70 GW) in the next decade, reaching 84.2 GW in 2050.
Panasonic launches power generating windows with perovskite solar cells
According to reports, Panasonic is planning to sell windows made of “power-generating glass”, with perovskite solar cells integrated into transparent panes, to deliver power for homes. The module reportedly has a conversion efficacy of 17.9%, which is said to be the second highest worldwide for a perovskite cell larger than 800 sq. centimeters, ( after China’s UtmoLight - 18.6%).
Panasonic has been developing the cells since 2014 but only recently completed a test project, which consisted of installing the innovative glass on the balcony of a model home in its smart-town project in Kanagawa prefecture.
Solliance partners reach new efficiency record with four terminal tandem configurations
Solliance partners TNO, imec/EnergyVille and the Eindhoven University of Technology, have reported a 18.6% efficient highly near infrared transparent perovskite solar cell. When combined in a four terminal tandem configuration with an efficient Panasonic crystalline silicon (c-Si) cell or with a Miasolé flexible CIGS cell, the configuration delivered new record power conversion efficiencies of 28.7% and 27.0%, respectively.
The researchers explained that four terminal tandems allow to build on experience and practices already available in the industry. In addition, four terminal perovskite/c-Si tandems can be applied broadly and are, for example, very beneficial in combination with bifacial c-Si solar cells which, depending on the actual albedo, can readily achieve a total power generation density as high as 320 W/m2.
Japan’s NEDO and Panasonic achieve 16.09% efficiency for large-area perovskite solar cell module
Panasonic Corporation has achieved an energy conversion efficiency of 16.09% for a perovskite solar module (Aperture area 802 cm2: 30 cm long x 30 cm wide x 2 mm thick) by developing lightweight technology using a glass substrate and a large-area coating method based on inkjet printing.
This was carried out as part of the project of the New Energy and Industrial Technology Development Organization (NEDO), which is working on the "Development of Technologies to Reduce Power Generation Costs for High-Performance and High-Reliability Photovoltaic Power Generation" to promote the widespread adoption of solar power generation.
