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.

Microquanta has announced the completion of what it claims to be the world's largest building-integrated photovoltaic (BIPV) project based on perovskite solar panels. Installed on the translucent roof of the University Student Entrepreneurship Center in Shenchi County, Shanxi Province, the project has a capacity of 17.92 kWp. 

Microquanta specified that its custom-designed double-glass perovskite modules measure 1,200 mm x 1,000 mm and achieve a light transmittance of around 40%, allowing daylight into the building interior while generating electricity.

Researchers from Singapore's Nanyang Technological University and France's University of Lille (CNRS) have developed a biomass-derived furan-based conjugated polymer, PBDF-DFC, enabling a simplified direct precursor integration fabrication method for hybrid perovskite solar cells (HPSCs). 

Unlike traditional thiophene-based polymers, PBDF-DFC reportedly exhibits high solubility in perovskite precursor solvents, allowing direct incorporation into the precursor solution. This direct precursor integration approach could significantly streamline the fabrication process, reducing steps and potentially lowering production costs. 

India-based P3C has announced a partnership with the National Institute of Solar Energy (NISE). 

P3C and NISE have signed a Memorandum of Understanding (MoU) to accelerate India’s transition to a low-carbon, sustainable future. This partnership will focus on advancing perovskite solar technology and powering next-generation solar solutions, including glass and flexible perovskite modules, tandem solar cells, and advanced PV innovations for both urban and rural environments. The two parties' shared goal is to make clean energy accessible, efficient, and scalable across India, from rooftops and farmlands to smart cities and remote villages.

Solaires Entreprises, a Canadian clean technology company pioneering perovskite-based photovoltaic solutions, has announced that it has received CAD$1,550,000 (around US$1,092,000) in non-dilutive funding from Sustainable Development Technology Canada (SDTC). 

This funding will support the continued advancement and commercialization of Solaires’ innovative perovskite photovoltaic technology, allowing their PVModules to be brought into new applications like transportation and building-integrated solutions. These advancements will enable more sustainable solutions for low-power electronic devices and will catalyze massive GHG savings in the transportation and energy markets.

Researchers from Linköping University, Cornell University, Westlake University and the University of Toledo have reported a low-cost, green-solvent-based holistic recycling method to restore all valuable components from perovskite solar cells (PSCs) waste.

The scalable, aqueous-based method to recycle perovskite solar cells could offer an environmentally friendly solution that minimizes end-of-life waste while maintaining performance. This addresses various sustainability concerns – such as toxicity, limited recycling options, and resource depletion – that pose significant challenges to the widespread adoption of PSCs.

An international team, including researchers from EPFL, CNR SCITEC, Fujian Normal University, Southern University of Science and Technology (SUSTech) and others, has used an n-type polymeric additive to stabilize C60 molecules for use in inverted perovskite solar cells. The researchers reportedly designed a solar cell with the highest efficiency value ever recorded for perovskite devices based on solution processed C60 electron transport layers.

The team explained that C60 is currently the best-performing type of ETL for perovskite solar cells, although it suffers from “significant” aggregation in solution, which makes a high-cost and complex thermal evaporation method necessary for its development. To solve this issue, it utilized an n-type polymeric additive to stabilize C60 molecules for solution processing. “We introduced an n-type polymeric additive, TPDI-BTI, constructed from the strongly electron-deficient dithienylpyrazinediimide (TPDI) and the imide-functionalized bithiophene (BTI) co-unit and applied it into the C60 ETLs,” the researchers explained. “By controlling the TPDI-BTI addition, we can systematically regulate the ETLs, including film formability and morphological stability, energy levels and electron transport dynamics, intermolecular interacting behaviors and interfacial contacts, and finally, the photovoltaic performance and long-term stability of the cells.”

Early bird pricing is still available for the 2025 Perovskite Connect Event, that will take place on October 22-23, 2025, in Berlin, Germany. The discount expires on February 15 (this Saturday), so this is the last chance to secure your ticket or exhibition package for the excellent industry-facing trade show.

This in-person event will unite leading experts from academia and industry to explore the latest advancements and challenges in perovskite technology. Distinctively, the conference will focus on an industry-oriented approach, emphasizing networking opportunities and strategies for market entry rather than solely technical discussions. Attendees can look forward to engaging activities such as tours, masterclasses, exhibition and more. Confirmed speakers and exhibitors include Microquanta, CEA Leti, Perovskia, Sofab Inks, PV-ART India, Heliatek, Aerosolar, SALD, Solaires, FOM Technologies, Solaveni, Noctiluca, and CHOSE.

Perovskite solar modules developer WattByWatt has raised CAD$975,000 (around USD$682,000) financing from the Canada's federal government, which will enable the company to increase its production capacity.  

WattByWatt offers its technology as a more efficient and less expensive alternative to traditional silicon-based solar cells, particularly to recharge or power batteries in electronic devices and smart card readers. The company claims its modules can function both indoors and outdoors. It can produce customized solar panels up to 400 cm². WattByWatt’s current portfolio comprises Perovton mini-PV modules to power electronic devices in the Internet of Things (IoT) for home and industry (IIoT). These can power smoke alarms, remote controls, keypads, locks, cameras, etc.

Perovskite solar cell developer, SolaEon Technology, has announced that its all-perovskite tandem solar cells, co-developed with Shanghai Jiao Tong University, have achieved a certified conversion efficiency of 30.58%. 

SolaEon says this achievement has been verified by the China Photovoltaic Testing Center (CPVT). The maximum power point tracking (MPPT) stabilized efficiency for these cells reached 30.49%, which the company claims is a new efficiency record for this technology.
