Scientists in the Middle East designed a flexible two-terminal organic/CIGS tandem solar cell for wearable applications. The device achieved an open-circuit voltage of 1.89 V, a short-circuit current density of 17.55 mA/cm2, and a fill factor of 82.79%.

US-based Thornova said its new panel features a power conversion efficiency spanning from 22.4% to 23.2% and a temperature coefficient of -0.29% per C. The company is a subsidiary of China-based manufacturer Sunova Solar and is currently planning a cell and module factory at an unspecified location in the United States.

An international research team explained that, although inverter clipping is initially effective in mitigating soiling losses, these losses could become more visible with time, as solar module degradation makes clipping less frequent. They also warned that inverter undersizing alone may not be enough to mitigate soiling losses and suggested cleaning as an additional way to reduce them.

The Turkish government has decided to impose a tariff of $25 per square meter on solar modules imported from Vietnam, Malaysia, Thailand, Croatia, and Jordan.

The new panel has a white backsheet and a temperature coefficient of -0.34/C. It weighs 4.1 kg per m2 and, according to the manufacturer, supports all types of installation methods, including roof adhesive and removal mechanical mounting.

The International Renewable Energy Agency (IRENA) released a new report on the sidelines of the Berlin Energy Transition Dialogue this week describing the actions needed so the world complies with targets set at the recent COP29 conference in the United Arab Emirates. IRENA President Francesco La Camera says renewables are the only energy sources with the speed and scale to achieve the ambitious targets set in Dubai.

A Spanish group of researchers has investigated how much agricultural production may be hosted by existing ground-mounted PV plants using dual-axis trackers. They outlined a new methodology that reportedly enables to quantify how much space around and beneath the panels can be uses for agricultural purposes.

Researchers in Bangladesh have designed a dual-junction tandem solar cell with a bottom device based on iron disilicide (FeSi2), an emerging absorber material know for its high thermal stability and good optoelectronic properties. Their simulation showed the advantage of combining the larger bandgap of the top cadmium telluride cell and the smaller bandgap of the bottom FeSi2 cell.

The researchers simulated an all perovskite solar cell offering the advantage of effectively harnessing sunlight across a wide range of wavelengths. The device has the potential to achieve an open-circuit voltage of 3.76 V, a short-circuit density of 10.70 mA/cm², and a fill factor of 69.00%.

The novel methodology is reportedly able to track global maximum power point and reduce power losses in partially shaded PV systems by up to 33%. It uses a backstepping controller (BSC) algorithm to adjust the pulse width modulation signal and a genetic algorithm to compute the BSC gains to achieve an optimal PV system outcome.
