As new cell and module concepts move into large-scale production, and efficiencies are pushed ever higher, manufacturers of flash testing equipment must innovate to ensure their tools can provide reliable measurements, and cope with ever expanding production throughput. The expansion of bifacial technology beyond niche applications in particular raises new issues for flash testing standards. pv magazine spoke with several flasher manufacturers to shed light on the latest developments in this segment.
Azure Power has raised the capital since June 30th, and says it is “the largest amount of financing raised by a solar power company in India during this period”. Azure says the fund leaves it well positioned to deliver a 2 GW project pipeline.
A new report published by business consultants Frost & Sullivan expects around 90 GW of new solar installations by the end of 2018, in line with the predictions of other leading analysts. It further notes that PV remains the world leader in renewable energy capacity, and that markets are moving away from feed-in tariffs to make increasing use of auction models and private PPAs.
A team of researchers from the Okinawa Institute of Science and Technology (OIST) has developed a new process for the production of perovskite solar devices; and reports a 5x5cm² device with an efficiency above 15%. The researchers worked with a 1 micron thick active layer, considerably thicker than in many other perovskite devices, and state that this helped achieve better long-term stability.
As backsheet manufacturers aim to keep up with cost reductions up and down the PV supply chain, new processes and materials are appearing, with claims to offer better performance as a moisture barrier, as well as better acetic acid permeability and higher reflectivity, among other features. pv magazine examines the state of the market for PV backsheets, and takes a look at some of the new material innovations that are gaining ground with module manufacturers.
Researchers from the University of California, Los Angeles, have set a new record 22.4% conversion efficiency for a tandem cell combining a lead-based perovskite layer with CIGS technology. The record has been confirmed by the U.S. National Renewable Energy Laboratory.
Research conducted over several years by scientists at the Massachusetts Institute of Technology (MIT) demonstrates that air pollution in cities can put a dampener on the performance of PV panels which, if not taken into account, can threaten a project’s viability.
Indian energy company Azure Power recently announced that it has connected a 50 MW PV project in the Indian State of Andhra Pradesh. The company states that the completion of this project brings its portfolio of operational solar assets past the 1 GW mark.
U.S. technology company Microlink Devices has achieved a record efficiency of 37.75% on its triple junction thin film cells. The lightweight cell achieves a power density of more than 3000 W/kg, and is designed for use in satellites and unmanned air vehicles (UAVs). The new efficiency record is confirmed by the National Renewable Energy Laboratory.
A new report published by the United Nations Food and Agriculture Organization outlines the benefits of solar powered irrigation systems to both large and small scale farming operations in developing countries. The report also stresses the need for comprehensive management and regulation of such systems, to avoid unsustainable water use.
