A partnership between PXP Inc and Tokyo Gas Co is working on developing film cells of the Filmtype Chalcopyrite for industrial roofs with a low tax capacity. Elsewhere, a coalition of partners inner windows with perovskiet solar cells in Tokyo’s Telecom Center building installs.
A project between the Japanese Green Tech Startup PXP Inc and Tokyo Gas CO develops a film type Solar cell for installation on industrial roofs with a low tax -bearing capacity.
A statement released by the two companies says that the work combines PXP’s chalcopyrite solar cells, which weigh less than 1 kg per square meter, with the construction methods of Tokyo gas to use the cells on low tax roofs, such as slate roofs.
It added that the capacity on such roofs in Japan is estimated at around 169 gigawatts by 2050, more than double the current installed capacity of the country.
The project, invoiced as the first time that chalcopyrite solar cells are installed on roofs with a low tax -bearing capacity in Japan, works on determining panel structure and construction methods and determining the performance, sustainability and safety of such solar panels.
The two companies want to launch the service in the tax year 2026.
Elsewhere in Japan, a group of Tokyo-based partners is working on a building-integrated photovoltaic (BIPV) pilot project.
In the project inner windows with perovskite solar cells will be installed in the Telecom Center building in the AOMI district of Tokyo.
The Tokyo Metropolitan Government’s Bureau of Port and Harbor has signed an implementation agreement with Toshiba Energy Systems & Solutions Corporation, YKK AP Corporation, Director’s Corporation and Tokyo Teleport Center to deliver the project.
It is subsidized by the Tokyo Metropolitan Government’s Bureau or Environment via a support program for developers.
Toshiba said that 10 solar cells from the next generation of film type are installed. The performance of the power generation of the cells will be analyzed to support their implementation in other existing buildings.
Installation work have been set to start at the beginning of August, planned with the pilot until January 2026.
