Technology and R&D

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.

Soltec has developed a floating PV tracker with pumps in the central tank for mobility and ballast, enabling operation in wind gusts above 100 km/h.

A research team including scientists from Italian module manufacturer 3Sun has tested new zirconium-doped indium oxide electrodes in commercial heterojunction solar modules. The new electrodes reportedly achieve the same performance as their counterparts based on indium tin oxide and paves the way for lower indium consumption in heterojunction products.

JinkoSolar says its 182 mm tunnel oxide passivated contact (TOPCon) solar module has achieved a conversion efficiency of 25.42%.

University of New South Wales researchers have created vortex generators that can reportedly reduce the operating solar module temperature by up to 2.5 C. They built two different prototypes, based on aluminum and a conductive 3D printable polymer, and tested them under several scenarios in an experimental setting deployed in Sydney.
