Satellite breakthrough enables accurate panel-scale temperature mapping for solar farms
A Chinese research team has developed a novel panel surface temperature retrieval model using moderate-resolution thermal infrared satellite imagery to accurately estimate the surface temperature of photovoltaic panels in utility-scale solar farms. The method accounts for the three-dimensional structure of PV arrays, changes in panel area with viewing angle, and the low emissivity of PV panels. By separating PV modules from inter-row gaps within each satellite pixel, the researchers were able to isolate the radiative signal attributable to the PV modules, resulting in a more accurate retrieval of panel surface temperature. Improvements in satellite-derived thermal data accuracy have led to a 3-5% decrease in bias in photovoltaic (PV) power simulation, with a focus on understanding and incorporating shaded gaps between rows of panels. The new approach was presented in the International Journal of Applied Earth Observation and Geoinformation by scientists from various institutions in China.

Using a bird’s structural-color trick to color solar modules
Researchers in China have developed a method for coloring PV modules using quasi-ordered photonic pigments that scatter light instead of absorbing it, increasing efficiency. Inspired by blue-feathered birds, the team created silica-polyacrylate structural color pigments for the modules. By varying the size of silica microspheres, different colors were achieved, with PCE enhancements of over 50% compared to traditional absorbing pigments. A new study shows that colored PV modules integrated into facades can deliver a high energy yield in both high and low latitude locations, with potential for building-integrated photovoltaics with visually appealing and efficient results.

View article, Scientists achieve 27% efficiency in a co-deposited inverted perovskite, Scientists in China have developed a new technique to prevent self-assembled molecules from clumping together and degrading co-deposited inverted perovskite cells. The approach enabled the highest certified power conversion efficiency reported for the architecture.
Researchers from China have developed a novel approach to improve the performance of co-deposited inverted perovskite solar cells by addressing the issue of self-aggregation of self-assembled molecules (SAMs). They designed an asymmetric SAM, PhBr-4PACz, to suppress aggregation and promote SAM accumulation at the bottom interface, enhancing adhesion and coverage. Additionally, they introduced a grain-boundary crosslinking additive, AVIMCl, to improve device stability by suppressing SAM diffusion. The research resulted in a certified power conversion efficiency of 27.03% in co-deposited inverted devices, the highest reported for this architecture to date. The approach also demonstrated versatility by achieving high efficiencies on different substrates and device architectures. Chen and his team are working on a co-deposition strategy to improve the efficiency of solar modules by suppressing SAM diffusion and optimizing crosslinking, with plans to scale this strategy to large-area modules and adapt it to industrial coating techniques. Collaboration with scientists from Shanghai Jiao Tong University and Shandong Normal University contributed to the study, aiming to increase open-circuit voltage and reduce recombination losses through further optimization of the SAM and crosslinker.

Storing renewables with compressed air in urban heating pipeline
Researchers in China have developed a heating pipeline compressed-air energy storage (HP-CAES) concept that repurposes urban district heating networks for storing surplus renewable electricity. The system stores compressed air and recovered compression heat within existing pipelines, improving efficiency and reducing infrastructure requirements. The method allows for simultaneous heating and energy storage functions without complex modifications, enabling widespread application in urban heating networks. The HP-CAES system was designed using thermodynamic modeling and simulations, with a total compressed-air storage volume of 38,334.69 m3 in three pipeline sections. A study compared an adiabatic compressed air energy storage (HP-CAES) system using a heating pipeline as storage with a metal tank-compressed air energy storage (MT-CAES) system. The HP-CAES system showed higher energy storage density and efficiency, especially when using sliding pressure mode. Optimizing pressure ranges and stage numbers is crucial for balancing energy efficiency, storage density, and ecological performance. The HP-CAES system also had lower investment costs and shorter payback periods compared to the MT-CAES system, making it a favorable option for urban heating networks.

China solar exports hit all-time record in March as Africa, Asia demand jumps
In March 2026, China exported a record volume of solar components, totaling 68 gigawatts in solar capacity, as fossil fuel prices rose and tax rebates for clean technology ended. This surge in demand led to 50 countries setting all-time records for Chinese solar imports, with African nations experiencing a significant increase in demand. Despite China's decision to end tax rebates, African countries are continuing to rapidly expand their solar energy capacity, with prices expected to rise but not reverse the clean energy transition. Asian nations, including India, also increased their imports of Chinese solar components, reflecting a global trend towards solar energy adoption.

Electric car sales race ahead in SE Asia and Latin America amid oil supply crisis
Global electric car sales are expected to reach 23 million this year, accounting for 28% of total car sales, with nearly 30% of cars sold being electric. The war in Iran has led to soaring petrol and diesel prices, prompting drivers to turn to electric vehicles as a cheaper alternative. Sales of battery electric cars and plug-in hybrids have seen significant growth in Asian countries outside of China, Latin America, and Europe. In Europe, one in three cars sold this year is projected to be electric, while in China, monthly sales have grown to over 60% of total car sales. Sales are also expected to rise by more than 50% in Asian countries and 45% in Latin America this year. The energy crisis caused by the Middle East war has highlighted the benefits of driving an electric car, leading to potential growth in EV sales. The road transport sector is the largest consumer of oil, and governments' response to soaring oil prices could shape the global car market. Electric vehicles are now seen as an alternative to oil dependence for transport, with a quarter of all new cars sold in 2025 being electric. Southeast Asia, heavily dependent on fuel imports, has seen spectacular growth in electric car sales in response to the energy crisis. Countries in the region are expanding EV tax incentives and implementing supportive policies to boost EV sales. In 2025, Chinese carmakers dominated the electric vehicle market, with technological advances and cheaper prices driving EV deployment in China. Nearly 40% of new car sales in Vietnam were electric, surpassing levels seen in most European countries. The cost of owning an electric truck in China is now competitive with owning a diesel one, leading to a doubling of the electric truck market in just two years. Cheaper EVs from China have led to a doubling of car exports in 2025, with Chinese automakers manufacturing 60% of electric cars sold worldwide. Intense competition domestically in China is pushing electric car manufacturers to seek export opportunities overseas.
