The Bangladesh Standards and Testing Institution (BSTI) says its new solar module testing laboratory in Dhaka marks a major step toward enforcing quality standards and supporting the nation’s export ambitions.

Scientists in China have developed a new deep learning model based on the so-called “You Only Look Once” algorithm, which requires only one forward propagation pass through the neural network to make predictions,

Researchers at Nanyang Technological University have demonstrated a method to integrate chemically inert low-dimensional interface materials into the fabrication of inverted perovskite solar cells. Their prototype solar cells retained over 93% of the initial power conversion efficiency of 25.1% after 1,000 hours of operation, and 98% after 1,100 hours at 85 C.

A group of scientists in China conducted a comprehensive review of existing low-cost photovoltaic monitoring approaches. They found that only 11 out of 88 studies related to PV monitoring incorporate machine learning. The researchers urge the scientific community to place greater emphasis on lightweight machine learning solutions and smartphone-based integration.

Researchers in India have developed a novel layout design tool to identify the optimal locations for solar panel installation on undulating terrain. The tool consists of two components: a filtering module that excludes unsuitable land patches, and an algorithm that determines the optimal distribution of panels across the remaining usable area. The approach was demonstrated on a test site in India.

IEC Standards help to make the grid more resilient as the impact of climate change intensifies.

Scientists in China have investigated how frame perforations can help reduce the operational temperatures of solar modules through air cooling. Their findings show that the number of perforations must be carefully calibrated, and that more is not necessarily better.

The cell reportedly exhibits only a 0.4% efficiency loss compared to a reference device that underwent full silver metallization.

Researchers in Spain reviewed six models used to calculate incidence angle modifier (IAM) losses in photovoltaic systems. They identified the Martín-Ruiz model as the most comprehensive, as it uniquely accounts for additional angular losses caused by soiling.

UK researchers find that smart, centrally controlled air-source heat pumps could slash peak electricity demand. The technology not only keeps homes comfortable but also boosts grid flexibility and cuts emissions.
