Researchers in China found that PV plants in arid regions create a measurable cool island effect that varies strongly with season, location, and plant design, influencing surrounding vegetation in complex and spatially uneven ways. They showed that cooling intensity and distance differ widely across sites, are driven mainly by plant morphology,

Indian scientists have fabricated perovskite mini-modules with reduced graphene oxide interface engineering, achieving 16.6% efficiency and over 1,300 hours of stable operation. The graphene oxide layer improves film quality, reduces defects, enhances charge transport, and enables scalable fabrication, offering a promising route toward efficient and durable perovskite solar modules.

Solar energy, driven by excellent resource conditions and rapidly improving economic attractiveness, is expected to emerge as a bulk energy supplier in future energy systems. The self-limiting effects of solar power can be circumvented through solar-hybrid solutions, such as PV-geothermal hybrid configurations.

A review of 60 renewable energy studies finds that by 2050, solar PV and wind could supply 80–100% of electricity, but overly conservative Capex assumptions and simplified PV modeling often underestimate deployment potential. While future PV costs depend on supply chains and geopolitical risks, historical experience suggests medium-term risks are manageable, and material constraints are being resolved.

A Czech team developed an IoT system using MQTT to autonomously cool PV panels, boosting daily energy yield by 7.38% with a positive net energy balance.

The TOPCon solar cells with fabricated with screen-printed, fire-through copper rear contacts and silver front contacts, using laser-enhanced contact optimization (LECO) to significantly reduce contact resistivity. Optimized copper cells achieved 24.3% efficiency, comparable to Ag-contacted cells, with excellent stability.

A research team has developed a solvent-free method using ultrasonic cavitation to delaminate end-of-life crystalline-silicon PV modules, fully separating the glass and front EVA layer while partially releasing c-Si fragments. The proposed approach achieved an 82.2% mass-based delamination efficiency, highlighting ultrasonic cavitation as a sustainable alternative for PV module recycling.

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.

An international study has demonstrated that utility-scale solar PV paired with hydraulic hydro storage (HHS) could reach an LCOE as low as $0.022/kWh in select U.S. regions. The system could provide GWh-scale, cost-competitive, and highly reliable long-duration storage, capable of powering large commercial districts with minimal environmental impact.

A UNSW-led team found that annealing conditions significantly affect stress, strain, and microstructure in copper-plated heterojunction solar cell contacts, with fast annealing increasing microstrain in both copper and indium tin oxide.
