A new UNSW study shows that laser-enhanced contact optimization (LECO) can boost industrial TOPCon solar cell efficiency by improving contact properties and reducing recombination losses. By combining optimized firing conditions with LECO “repair” of contacts, the approach balances recombination and resistance, offering a practical path for conventional TOPCon cells to compete with PV technologies offering higher efficiencies.

Figures from Singapore’s Energy Market Authority indicate that the country had a record year for solar deployment in 2025. Cumulative capacity surpassed 2 GW, leading to Singapore’s 2030 solar target being increased to 3 GW.

In its first monthly column for pv magazine, UK-based consultancy Ricardo, part of the WSP Group, explain how UK will soon allow low-cost plug-in solar panels under 800 W to be installed without a qualified electrician, making home solar more affordable and accessible. These portable systems, expected on sale by summer 2026, could significantly boost household solar adoption while complementing the country’s wider renewable energy growth.

Polysilicon prices have fallen sharply over recent weeks due to persistent oversupply and weakening demand, briefly dipping to low levels before stabilizing slightly above CNY 50 ($7.31)/kg, though still near historical lows and below production costs. OPIS analyst Summer Zhang tells pv magazine that despite policy signals and potential future regulations, unclear implementation and continued excess capacity mean market conditions remain weak, with further demand declines and possible production cuts or discounted sales expected in the near term.

Analysis from Wiki-Solar finds the world’s 33 largest utility-scale solar markets had a cumulative capacity of 1,008 GWac by the end of last year.

The Bangladesh Power Development Board plans to build a 442 MW solar plant near the Rampal Power Station with a $200 million investment, targeting the country’s largest installation and lower tariffs than comparable projects.

An international study found that the specific power of commercial silicon solar modules increased from 8.5 W/kg in the early 2000s to 23.6 W/kg today, driven by advances in module design, bifaciality, and temperature management. The researchers highlighted that glass and framing dominate module weight, and considering operating conditions like nominal operating cell temperature and rear-side illumination is essential for accurate PV system design.

Switzerland’s photovoltaic market slowed in 2025, with newly installed capacity falling 15% to 1,526 MW, according to Swissolar. Despite the decline, growth in residential storage, building electrification, and EV integration points to a gradual market recovery.

IT security firm Jakkaru has identified a vulnerability in microinverters from AP Systems that could enable a “kill switch” scenario, potentially shutting down tens of thousands of inverters simultaneously and disrupting grid operations.

Greece installed around 1.9 GW of new solar capacity in 2025, bringing total installed solar capacity to roughly 11.5 GW, according to industry estimates.
