Modules & Upstream Manufacturing

InfoLink Consulting says global module shipments rose 10% to 247.9 GW in the first half of 2025, with JinkoSolar narrowly pushing past Longi and tunnel oxide passivated contact (TOPCon) tech accounting for more than 94% of the total.

Insolation Green Energy has commenced commercial operations at its new 3 GW PV module manufacturing plant in Rajasthan.

Chinese researchers, led by a research team from PV Technology Center of Tongwei Co., Ltd, used a sequential annealing process in the fabrication of tandem solar cells, featuring a wide bandgap perovskite top cell on a fully-textured commercial crystalline silicon heterojunction bottom cell. The resulting device had a certified power conversion efficiency of 31.4%, outperforming a 29.43%-efficient control cell.

Vikram Solar Ltd’s Initial Public Offering (IPO) received a strong response on Day 1, with the non-institutional investors’ portion subscribed 3.84 times and the retail portion 1.37 times.

Tindo Solar, Australia’s lone producer of PV modules, has officially released a new generation of TOPCon N-type solar panels, including an all-black version featuring an output of 475 W and conversion efficiency of 21.9%.

Indian researchers simulated a novel pairing of a CsGeI3 lead-free halide perovskite top cell with a copper-indium-gallium-selenide bottom cell. The resulting tandem device has the potential to achieve a power conversion efficiency of 26.06%

UNSW researchers have investigated the impact of two types of soldering fluxes on TOPCon solar modules under damp heat conditions and have found that “no-clean” soldering fluxes can cause severe corrosion of front silver-aluminum contacts. The researchers have also found that denser metallisation structures and lower aluminium content improve corrosion resistance.

Entrepreneur and investor Nikhil Kamath has invested INR 137.5 crore in Goldi Solar, a Gujarat-based solar PV module manufacturing company. The investment will enable Goldi Solar to expand its production.

The revised timeline for the implementation of the Approved List of Models and Manufacturers for Solar Cells (ALMM-II) offers temporary relief to solar developers amid persistent domestic cell supply constraints. However, it also introduces fresh regulatory challenges, particularly around tariff renegotiations for recently awarded projects, according to analysts at CareEdge Ratings.

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.
