How to convert PV plants with dual-axis trackers into agrivoltaic facilities

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.

IIT Kanpur event focused on sustainable innovation and entrepreneurship starts today 

IIT Kanpur’s annual event Abhivyakti’24, scheduled for March 15 and 16, 2024, provides a platform for the startup ecosystem to collaborate and develop sustainable solutions for a better future.

Perovskite thin film: Out with the old, in with the new

Silicon-perovskite tandem solar requires optimization of both approaches, and embodies the weaknesses of each. Meanwhile, the use of pure thin-film devices offers a cheaper, simpler, and more sustainable PV solution for the United States.

Indian scientists design 26.24%-efficient triple-junction all perovskite solar 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%.

Battery prices collapsing, grid-tied energy storage expanding

From July 2023 through summer 2024, battery cell pricing is expected to plummet by more than 60% due to a surge in electric vehicle (EV) adoption and grid expansion in China and the United States.

New approach to improve MPPT in partially shaded PV systems operating at high temperatures

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.

New tech to remanufacture recycled perovskite solar cells

An international research team has developed a novel way to remanufacture fully encapsulated perovskite solar cells after recycling. The researchers say the devices can achieve 88% of the original efficiency of the products.

Triple-junction perovskite–perovskite–silicon solar cell achieves record-breaking efficiency of 24.4%

Developed by scientists in Germany, the triple-junction cell is based on a perovskite top cell with an energy bandgap of 1.84 eV, a perovskite middle cell with bandgap of 1.52 eV, and a silicon bottom cell with a bandgap of 1.1 eV. The device achieved an open-circuit voltage of 2.84 V, a short-circuit current of 11.6 mA cm–2, and a fill factor of 74%.
