Research & Development

A U.S. research team has used protein bacteriorhodopsin to improve the efficiency of what it called ‘bioperovskite’ solar cells. The scientists used Förster Resonance Energy Transfer to predict the strength of long-range excitonic transport between the perovskite and protein layers.

Research institutes have moved quickly to emulate the successes observed in a test installation at Jodhpur as India races to meet an ambitious target of doubling agricultural income by 2022.

The Department of Science & Technology, Government of India, and the Ministry of Science and Technology of State of Israel will fund joint research on advanced materials for next-generation solar energy utilization and energy storage. The deadline for the submission of proposals is December 5.

The ministry has invited proposals for high-efficiency perovskite solar cells, solar panel recycling, hybrid inverters and new applications that combine solar and storage, among others.

Few in the industry predicted the speed at which monocrystalline technology would develop, or the impressive cost reductions it would achieve by 2019. This has left producers of multicrystalline products facing rapidly shrinking market share and struggling to compete on a cost per watt basis. Many are now turning to cast mono processes, essentially creating a monocrystalline, or ‘mono-like’ silicon ingot in a multicrystalline furnace, to reach higher efficiencies and extend equipment lifetimes.

“Solar cells prefer to operate in a refrigerator,” says UNSW Professor Martin Green. His global research team is now identifying viable ways to cool down solar PV modules while amping up energy production to an unprecedented level.

The preliminary proposals must reach the ministry by June 30. These will be examined by a committee and the shortlisted parties will be invited to submit final proposal.

By 2030, according to the United Nations nearly half of the world’s population will be living in water-stressed areas if no preventive actions are taken. Water reuse technologies and measures to reduce water usage can only serve as temporary relief for the upcoming water crisis. Jiajun Cen, CTO at Desolenator, lays out the case for solar powered desalination as a solution.

And the analyst expects that annual new additions figure to rise to 10.6 GW in 2025. This year the U.S. will surpass South Korea as the largest storage market due to new capacity for solar-plus-storage projects. In Japan and Australia, growth will be spurred by the termination of FIT programs.

As the nation aims for 100 GW of solar capacity by 2022 it is staring at up to 1.8 million tons of PV waste by 2050. A solar waste management seminar organized by consultancy Bridge To India in New Delhi brought stakeholders together to discuss how a PV waste management system could help.
