Technology and R&D

US scientists have analyzed the impact of “seasoning” a formamidinium lead iodide solution with two-dimensional (2D) perovskites. They have found that the template improved the efficiency and durability of their solar cells.

Researchers from Chinese and Malaysian universities have compared studies demonstrating the use of artificial intelligence to solve PV integration problems. They say that AI will bring revolutionary improvements in the efficiency, reliability and predictability of solar power generation.

The European Solar Test Installation (ESTI) has confirmed Longi’s achievement of a world record-breaking efficiency rating of 34.6% for a perovskite-silicon tandem solar cell.

A UK-based research team has calculated the global potential of deploying floating solar arrays on almost 68,000 lakes and reservoirs. It found some countries could generate the majority of their electricity needs from floating solar panels, while five could meet all their electricity demand.

Conceived for use in wearable electronics, the micro-power system utilizes a MPPT structure based on a customized FOCV algorithm, a DC-DC converter, a load or a rechargeable battery, a flowchart of MPPT, and a microcontroller.

The Chinese manufacturer said its new photovoltaic air conditioner is available in three versions with a cooling capacity ranging from 12.1 kW to 16 kW and a heating capacity of 14 kW to 18 kW. It can be used for both residential and commercial applications.

The Chinese manufacturer claims its new MIT-5000-8T product is currently the largest and the most efficient microinverter on the market. It can accomodate eight solar modules and is said to be particularly suitable for large-size residential PV systems or commercial applications.

A team of researchers from two Chinese universities achieved a bifaciality factor of 99.1% with a semitransparent organic cell, the highest reported bifacial factor in such cells to date. The cell also achieved a power conversion efficiency of 12.5% and an average visible light transmittance of 22.9%.

Maxeon’s Interdigitated Back Contact (IBC) solar panels were found to disperse heat evenly, leading to lower operating temperatures in the shade and reduced degradation.

China’s Utmo Light showcased its first full perovskite PV module at this week’s SNEC PV trade fair in Shanghai, underscoring the technology’s ongoing shift toward commercialization.
