The US Navy has funded Danish research on preventing biofouling while maintaining visible light transmission on underwater solar cells. The top solution uses ultra-low concentrations of nano-sized, seawater-soluble pigments. Power generation stayed close to 100% after 13 weeks underwater.

Scientists have used hydrometallurgical and electrochemical processes to recover pure silver from solar cells. The proposed technique also utilizes a method known as electrodeposition-redox replacement, which reportedly increases the silver recovery rate.

EDF Renewables says it has won a tender to build and operate Israel’s largest PV plant, a 300 MW project near Dimona, with a bid under $0.019/kWh – the lowest price ever in the Israeli market.

Researchers have covered part of a rooftop solar plant with a different numbers of shading cloth layers to measure their power, current, and voltage. They have been able to identify a point after which the value of system current and maximum power is no longer sensitive to shading heaviness.

Scientists have simulated dozens of electron transport layer-free cell structures and have identified the optimal design with a Zr:In2O3 front transparent electrode, a CuSCN hole transport layer, and a NAN rear transparent electrode. They have also optimized its thickness and bandgap.

Using a range of machine-learning techniques, a group of scientists found that PV systems can significantly increase the value of a property in the United Kingdom. The analysis was based on property data from Zoopla, one of the leading providers of UK property listings, and price paid data sourced from the government’s Land Registry from 2012-2018.

The Israeli authorities have introduced new regulations requiring rooftop PV on new large buildings, with plans to install 3.5 GW by 2040. The minimum production capacity has been set at 5 kW.

Researchers have designed a new tracking system that utilizes an arithmetic optimization-based PID controller. The proposed tracker uses two different sensor types – a UV sensor and a micro-electromechanical solar (MEMS) sensor. The first one calculates the intensity of UV radiation received from the sun, and the second one forecasts the sun’s path across the sky.

The Chinese manufacturer’s new battery energy storage system consists of an inverter ranging in size from 5 kW to 13 kW and a storage system of 10 kWh to 30 kWh. Up to five units can be connected in parallel.

Trina Solar says it has launched mass production of 430 W to 455 W full-black PV modules. The Vertex S+ panels have efficiencies of up to 22.8% and weigh 21 kg, with a 1.6 mm x 1.6 mm dual-glass design.
