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.

Microquanta has reportedly announced that its 810 cm² medium-sized perovskite module has achieved a certified full-area power conversion efficiency of 21.86% (average of forward and reverse scan: 21.83% forward, 21.89% reverse), as verified by the National PV Industry Measurement and Testing Center (NPVM).

The company called this a new efficiency record for perovskite modules of this size. Microquanta stated that the module incorporates its proprietary cryogenic laser repair technology, which in addition to significantly enhancing module efficiency also greatly improves module stability. Microquanta plans to apply this technology to its upcoming GW-scale perovskite production line, set to commence operations in March this year. The company has set a target of surpassing 20% conversion efficiency and achieving a 25-year lifespan for large-area modules with a size of 2.88 m².

Toyoda Gosei, part of the Toyota Group, has announced its plans to start a trial of smartwear fitted with perovskite solar cells, as clothing that can generate power.

Toyoda Gosei has been conducting joint development with Enecoat Technologies, a startup specializing in perovskite technology, since investing in the company in 2023. Now, as a product application of perovskite solar cells, the companies have made prototype smartwear that can be fitted with these solar cells manufactured by Enecoat Technologies for functions such as health management with various sensors and heating/cooling, using the generated power.
