Technology and R&D

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.

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.

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%.

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.

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.

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.

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%.

Tata Chemicals Ltd has collaborated with IITB-Monash Research Academy for research on the transformative potential of perovskite materials in the field of clean energy.

Scientists in Korea have developed a compressed air storage system that can be used as a combined cooling, heat, and power system and provide heat and power to solid-oxide electrolysis cells for hydrogen generation. It showed an overall roundtrip efficiency of 121.2% and over-unity efficiencies in the range of 100% to 120%.

Canada-based microinverter company SPARQ Systems has entered into a partnership agreement with JioThings, a fully owned subsidiary of Jio Platforms Ltd. of Reliance Industries, to supply the Indian conglomerate with PV microinverters.
