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.

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.

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.

Green Climate Fund (GCF) has approved a $24.5 million investment in Avaana Capital’s Climate and Sustainability Fund for technology-driven climate solutions.

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.

Under the Net Zero Buildings Initiative, Mahindra Group and Johnson Controls have launched a cost-free toolkit that will help building and facility owners to learn about the best practices of sustainable buildings, implement tools to assess building parameters, identify and implement conservation measures, and understand building regulations in India, available incentives, technology, financing models, and more.

Delta Electronics, which has been present in India for the last 20 years, recently launched its containerized data center solution in the country. With all subsystems such as UPS, power distribution, battery, cooling, and racks well integrated, this plug-and-play solution ensures rapid deployment for edge computing applications in the IoT world. On the occasion, pv magazine spoke to Rajesh Kaushal, vice president of Delta Electronics India, about their containerized data center solution, lithium-ion battery and solar inverter business, and future plans for India. 

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.
