2D/3D perovskite solar cell based on dopant-free HTL achieves 25.9% efficiency
An international team of researchers has demonstrated a novel solvent process for pure and highly crystalline 2D perovskites, which they demonstrated in 2D/3D perovskite solar cells. A n-i-p champion perovskite solar cell had a power conversion efficiency of 25.9%, retaining 91% of the initial performance after 1,074 hours at 85 C using maximum power point tracking.
Chinese PV Industry Brief: Canadian Solar profit drops 92% in Q1
Canadian Solar says its net profit plunged nearly 92% in the first quarter of 2025 on falling margins, while China Energy Engineering Corp. (CEEC) says the Shanghai Stock Exchange has approved its targeted A-share issuance to raise up to CNY 15 billion (USD 2.09 billion) for energy projects.
Middle East, Southeast Asia wafer makers ramp capacity amid record-low prices
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Qcells tandem solar module passes critical stress tests
Qcells says its perovskite/silicon tandem solar modules have passed several independently verified stress tests. The South Korean module maker claims the results meet benchmarks for commercial acceptance of its tandem tech.
How to assess bifacial PV system performance on sloped terrains
Scientists have developed a precursor formulation for different PV simulation tools that can help calculate the expected performance of solar farms deployed on hilly slopes. Validation tests against an experimental setup showed an error of less than 3%.
All agrivoltaic system designs at a glance
Researchers in Sweden and Italy analyzed the economics of one-axis, vertical, and elevated PV systems for agrivoltaic applications, finding that overhead agrivoltaic systems may perform better the further south they are installed. The discounted payback period and levelized cost of electricity were also calculated and compared.

Three year old Space Solar has completed an 18-month engineering design and development project for key parts of its modular space-based solar power system.
Chinese PV Industry Brief: New solar capacity hits 59.7 GW in Q1
China’s wind and solar capacity rose to 1,482 GW in the first quarter of 2025, overtaking coal for the first time, driven by 59.7 GW of new PV additions, according to the National Energy Administration (NEA).
Halocell, Australian researchers to scale lead-free solar tech
Australian perovskite cell producer Halocell Energy is partnering with University of Queensland researchers to accelerate the commercial production of lead-free solar panels based on record-breaking tin-halide PV cell technology.
Tandem cell or tandem module?
At Intersolar Europe in Munich, several companies presented their concepts for high-performance perovskite tandem photovoltaics. The first modules are expected to be available in the second half of the year. The different approaches by manufacturers are evident.
