The thermomechanical impact of plated copper contacts on heterojunction solar cells
UNSW researchers have found that annealing copper-plated contacts in heterojunction solar cells creates only localized stress. Their analysis also showed that, at typical annealing temperatures around 200 C, the probability of silicon fracture is very low.
Industry addresses UV degradation, hail risk in European solar modules
Industry leaders at pv magazine Week Europe 2025 said manufacturers are implementing measures to limit ultraviolet-induced degradation in tunnel oxide passivated contact (TOPCon) solar modules and strengthen resilience to hail damage to protect performance and reduce financial risk.
Solar powers the warfighter
2026 Defense authorizations highlight the need for U.S.-made photovoltaics in satellites to compete with foreign adversaries, writes Rob Gardner, vice president, congressional and regulatory affairs, for the SEMA Coalition.
Solar Stewardship Initiative publishes guide for solar supply chain
The Solar Stewardship Initiative’s (SSI) new buyers guide targets forced labor risk, supply-chain transparency, and compliance readiness in global solar procurement.
India’s Emmvee Energy signs 4.5 GWp TOPCon solar cell supply agreement
Emmvee Energy has signed a long-term supply agreement with a domestic buyer to deliver 4.5 GWp of tunnel oxide passivated contact (TOPCon) solar cells.
Perovskite-silicon tandem solar cell with steric complementary design achieves 32.3% efficiency
Researchers in China developed a monolithic perovskite-silicon tandem solar cell using a steric-complementary interface design, achieving a certified efficiency of 32.12% and enhanced long-term stability. This strategy optimizes molecular fit in the perovskite lattice, improving both charge transport and device longevity.
TNO offers mass customization line for integrated PV applications
The Dutch research institute’s highly automated research line offers customized, flexible solar semi-finished PV products to partners developing integrated PV applications.
How the world’s sunniest region tackles solar module soiling, cleaning
Researchers studying PV panels in Chile’s hyper-arid Atacama Desert found that cemented soiling can cause annual energy losses of up to 9.8%. Their combined field and laboratory work shows that dry cleaning leaves residue that accelerates future cementation, making wet cleaning the more effective long-term strategy despite higher costs and scarce water.
‘Back contact will reach cost parity with TOPCon before end of decade’
During a pv magazine Week Europe 2025 webinar, panelists forecast back contact (BC) solar cells’ market share will draw level with TOPCon towards the end of the decade, before tandem technology begins large-scale momentum in the early 2030s.
