Power product manufacturer Hangzhou Kelin Electric (KLEC) has reportedly announced its plan to issue A-shares to raise up to RMB 1.46 billion ($201.65 million).
Of the proceeds raised, RMB 1.261 billion ($174.19 million) will be allocated to a 1 GW high-efficiency perovskite solar module plant and the remainder for working capital.
Researchers from the University of North Carolina at Chapel Hill and Hong Kong Polytechnic University have addressed the challenges hindering the reception of wide-bandgap (WBG) perovskite solar cells, which are expected to play a key role in next-generation multi-junction solar cells but suffer from large photovoltage loss, poor stability and scalable fabrication in ambient air.
The team incorporated a reductive methylhydrazinium cation into WBG perovskites, which not only reduced defect density but also suppressed iodide oxidation and halide demixing, enabling scalable fabrication of efficient and stable WBG solar cells and modules in ambient air.
Tokyo Chemical Industry (TCI), a global supplier of laboratory chemicals and specialty materials, has started offering n-Type SAM forming agents. These materials can be used to increase the efficiency of perovskite solar panels.
TCI says that these new PANDI materials can be used as an alternative to electron transport layers (ETLs) such as TiO2 and SnO2. TCI's PANDI materials offer several advantages to perovskite n-i-p type devices:
Inverted perovskite solar cells without pre-depositing a layer of hole-transport materials (HTL-free PSCs) are promising, yet currently suffer from non-irradiative recombination at the perovskite/electron-transport layer (ETL) interface. Recently, researchers from China's Southern University of Science and Technology (SUSTech) and University of Macau reported a molecular complementary passivation (MCP) strategy by employing propylphosphonic acid 3-ammonium bromide (PPAABr) to cooperate with phenethylammonium bromide (PEABr) to mutually passivate surface defects of I and formamidinium (FA) vacancies by multi-coordination.
This passivation led to an obvious decrease in interfacial defect-state density and greatly improved exciton and carrier lifetime for the perovskite film. Moreover, MCP surface treatment pushes the perovskite surface Fermi level closer to that of ETL, thereby enhancing interfacial electron extraction. As a result, MCP-based HTL-free PSC achieved a record efficiency of 26.40% (25.92% certified). The encapsulated device retained 94.8% of its initial efficiency after 1,000 h of light soaking. The generality of the MCP strategy also generated a competitive efficiency of 23.66% for 1.68 eV wide-band-gap PSCs.
Microquanta has announced that it has achieved a conversion efficiency of 24.12% on small perovskite solar modules with a size of 19.48cm², certified by Fujian Metrology Institute of China’s National PV Industry Measurement and Testing Center, an authorized third party testing organization.
The efficiency of this perovskite module reportedly reached 23.93% for MPPT under STC, and its conversion efficiency reached 23.62% for forward scan and 24.12% for reverse scan under STC.
At the recent MWC 2025 exhibition, Anker Solix presented a raincoat with perovskite solar panels for charging electronic devices outdoors. The wearable charging prototype resembles a rain jacket with a slippery surface.
The jacket, which Anker Solix calls a cloak, is covered in about two dozen sewn-on flexible perovskite solar cells. An attached cable with a 30-watt USB-C output connects to a power bank or directly into your device, so you can charge your electronics as you walk around or relax outdoors.
A research team from East China University of Science and Technology has unveiled a novel method to extend the lifespan of perovskite solar cells by developing an ultrathin protective layer for perovskite materials using graphene and a special transparent polymer. Experiments showed this "armor" doubles materials' stress resistance, reducing the expansion rate to 0.08 percent from 0.31 percent.
Perovskite materials expand by over 1 percent when exposed to light, the team noted, adding that they repeatedly expand and contract under sunlight, like an inflating and deflating balloon, causing the internal crystals to squeeze each other and generate destructive forces, ultimately leading to structural failure. Cells protected by the team's new "armor" maintained 97% efficiency after 3,670 hours, or about 153 days, of continuous operation under simulated real-world conditions of intense light and high temperatures, marking the longest-ever stable operation period for perovskite cells and providing feasibility for commercial use.
It was reported that UtmoLight reached 18.1% efficiency with its 0.72m² perovskite PV modules, according to results confirmed by the US National Renewable Energy Laboratory (NREL).
The module also showed over 950 seconds of zero degradation under maximum power point tracking (MPPT) conditions, setting a new global efficiency record for perovskite modules of this size, according to the company.
Researchers from University of Electronic Science and Technology of China (UESTC), CNRS, Guangzhou University and China Jiliang University have developed a slot-die coating strategy based on pyrrodiazole (PZ) additives in the perovskite precursor solution to simultaneously immobilize lead iodide and formamidinium iodide.

This approach is meant to enhance wet film stability by suppressing colloidal aggregation, retards the crystal growth process, and ensures a consistent growth rate across the films. These effects can promote the formation of large, monolithic grains, enabling large-area perovskite films with homogeneous structure, excellent uniformity, and low defect density under ambient conditions. Using this strategy, the scientists achieved 10 cm × 10 cm inverted perovskite solar modules with a certified efficiency of 20.3% and retained 94% of initial efficiency after 1,000 h in standard testing, along with good working stability and excellent application demonstration, showcasing its great potential for industrialization.
TandemPV has announced it has secured $50 million in Series A funding and debt, led by Eclipse, with participation from Constellation Energy, Planetary Technologies, Uncorrelated Ventures, Trellis Climate, Tom Werner (former CEO of SunPower), Stifel Bank, CSC Leasing, and other existing and new investors. This investment will enable TandemPV to construct a commercial-scale manufacturing facility in the U.S., accelerating the adoption of its high-efficiency solar panels and allowing the U.S. to reduce its dependency on foreign manufacturers while increasing its energy security.
According to the statement, TandemPV's tandem perovskite panels currently achieve 28% efficiency and are projected to surpass 30% by late 2025, proving to be 30% more powerful than the average silicon solar panel. Tandem PV's panels lower labor and land costs, offering customers a lower total cost of ownership and a sustainable path toward decarbonization.
