Researchers have used guanidinium thiocyanate as a chaotropic agent to modulate the crystal growth rate during perovskite crystallization. They compared different concentrations of the guanidinium thiocyanate. Champion device efficiency was 22.34%.

Scientists in India have designed a system that uses PV panels, a proton-exchange membrane fuel cell, battery storage, and a supercapacitor. It also relies on an adaptive neuro-fuzzy inference system-based MPPT that reportedly achieves an efficiency of 98.7%.

China’s SAJ has launched its HS3 6-in-one home battery series, available in single- and three-phase configurations with 1,000 W to 15,000 W of PV input and up to 40 kWh of lithium iron phosphate (LiFePO4) storage.

Scientists in Hong Kong have developed a patch that effectively cools down PV panels and utilizes waste heat for freshwater production. It has three layers: an atmospheric water harvester, a thermal regulation layer, and an adhesive layer. Maximum power density reportedly increased by over 28% in a folded version of the ultra-cooling patch.

Scientists in Canada studied romaine lettuce growth under cadmium telluride thin-film solar modules with varying transparency and photosynthetically active radiation, and found Germany’s regulatory framework most effective for maximizing agrivoltaic benefits.

Scientists have created a solar cabinet dryer for mango slices, with PV-powered forced convection. Placing mango slices of different thicknesses inside, they have measured the operation of their device against two reference methods and have found that thermal efficiency reached 30%.

New research from Poland has suggested installing 891 PV panels along the entire tram platform and inter-track spaces of four major transportation hubs. The analysis showed that the PV system could power all of the city’s tram stops, the passenger information system, and meet 10% of demand from service depots.

An international researc team has included an interlocked self-assembled monolayer in perovskite indoor PV to enhance its stability and durability. Fabricating cells, mini modules, and a prototype device of an electronic price tag, the novel structure was tested. It was found to exhibit a lifetime approaching 6,000 hours.

Researchers in Egypt have developed new control strategies for managing frequency fluctuations during deloading of a photovoltaic plant. The proposed methodology combines a proportional–integral controller along with a rate of change of frequency controller.

Scientists have designed a cocoa pod splitting device that runs on five monocrystalline PV panels. They have simulated its operation and have found it can achieve a splitting efficiency of 98.92%.
