Technology and R&D

Scientists in Thailand have assessed which technology between PV, wind, or piezoelectric energy is better for powering street lighting and have found solar is the winning tech, as it proved both economically and technologically feasible.

Switzerland’s WSL Institute for Snow and Avalanche Research (SLF) is investigating how solar yield can be optimized in snow-covered terrain. It is envisaged the results will help to place PV systems on mountains so they make use of light that is reflected from neighbouring slopes.

The PV-driven redox flow battery can reportedly achieve a maximum solar-to-output electricity efficiency of 3.11% during a 36-hour period. The system incorporates a 25 cm2 heterojunction photovoltaic device and is based on a neutral pH aqueous iodine-bromine redox couple.

Solar sheep grazing helps to create a beneficial dual-use environment, found American Solar Grazing Association in a two-year study conducted at 31 different solar sites.

Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a contactless method to measure the performance of back-contact solar cells, enabling in-line assessment of key parameters such as efficiency, fill factor, and current-voltage characteristics.

An international team led by the U.S. National Renewable Energy Laboratory (NREL) has used ionic salt for the electron transport layer of a perovskite solar cell to improve device stability and performance. Test results showed a 26% power conversion efficiency with 2% degradation after 2,100 hours of 1-sun operation at 65 C.

Solargik has announced the official debut of its SOma Pro AI-powered platform for solar tracking and system diagnostics. The company says one of its main advantages is the ability to support smarter, faster decision-making.

Experts set to speak at the NetZero Milan Expo-Summit 2025 on May 15 have told pv magazine that tunnel oxide passivated contact (TOPCon) will remain the dominant cell technology in the near term due to ongoing advancements, despite rising competition from back-contact and heterojunction technologies.

Scientists in India have built a solar-powered thermic solar geyser prototype based on a nichrome wire heating rod and a flexible pipe heat exchanger with aluminum fins. The system is designed to generate domestic how water and can reportedly achieve a levelized cost of energy of $0.051 per kWh.

The Japanese manufacturer said its new heat pump system features a coefficient of up to 5.42 and a seasonal energy efficiency ratio of up to 33.2
