Research & Development

Indian scientists have developed a hybrid production method combining metal mesh and a metal-oxide layer over a glass substrate which they say brings down production cost by 80% compared to the tin-doped, indium oxide-based technology currently in use.

Light- and elevated temperature-induced degradation (LeTID) of PV cells can have far-reaching impacts on the efficiency of modules. Alison Ciesla and Brett Hallam of the University of New South Wales argue that accelerated testing, such as that included in the forthcoming IEC standards, is critical for LeTID identification and quantification in order to manage these impacts.

An Indian Institute of Technology research team analyzed around 300 studies about PV panel waste containing carcinogenic metals. The researchers said solar module recycling is not economically profitable and policy support is necessary to avoid panels being dumped in landfill.

December 5 is the last date to submit proposals for the joint research program on advanced materials for next-generation solar energy utilization and energy storage that will sponsor around 10 projects. The maximum funding available for all research projects approved is Rs40 million for the Indian side and 4,000,000 NIS for the Israeli side, for a period of two years.

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.
