Organic PV module based on ultra-narrow interconnections achieves record-breaking efficiency of 16.1%

New research from China shows that ultra-narrow interconnections may considerably improve organic PV performance. The scientists built a 11.08 cm2 panel with an impressive geometric fill factor of 98%.

PV fault detection method based on deep learning of aerial images

Conceived an international research group, the proposed model uses the convolutional neural network (CNN) architecture U-Net for image segmentation and the the CNN architecture InceptionV3-Net for fault classification.

University of the Western Cape launches 4 MW solar, storage tender

South Africa’s University of the Western Cape (UWC) has opened a 4 MW solar and storage tender, with proposals to include a PV carport system and an online monitoring and management platform. The tender follows a build, operate, and transfer model for up to 20 years.

PV-driven lighting solution for rural areas

Scientists have created a lighting system based on the AEM10941 solar harvester developed by Belgium-based E-peas. The system is reportedly able to provide a full brightness run time of 10 hours.

SolarEdge unveils inverters for smaller solar projects

Israel-based inverter maker SolarEdge has unveiled its new TerraMax Inverter, which boasts 99% efficiency and enables 200% DC oversizing. It features an integrated night-time PID rectifier and is paired with the company’s H1300 Power Optimizers.

Building-integrated photovoltaic system integrating PCM on sides

Scientists have designed a new building-integrated PV system that uses 30 mm of phase change material on each side of the wall. The array reportedly achieved superior thermoelectric coupling performance compared to reference BIPV systems without PCM.

Rotating, vertical floating PV system for offshore applications

An international group of scientists has designed a patented mooring tech and a vertical PV system that reportedly allows the bifacial solar panels to align with the prevailing wind direction to shed wind loads. Depending on a project’s latitude, the system can deliver different power yield.

Power-generating breakwaters for floating photovoltaics

Scientists from Singapore have designed new floating breakwaters integrating wave energy converters that can be used to reduce the impact of waves on offshore PV systems. Their analysis showed that the wave energy systems can achieve the highest additional power output when the wavelength is shorter.
