Research & Development

The tension between the cost cutting and performance boosting opportunities presented by new technologies and the tendency for risk aversion is never more evident than in PV module materials. This applies nowhere more than in backsheets, where new innovations are big on promise, but must convince manufacturers and the market of their long-term performance.

Kaco is launching a mass-produced string inverter with silicon carbide switches onto the market following 10 years of discussion about the technology within the industry. In the 100 kilowatt plus segment, the technology produces small, lightweight devices with few components.

Co-extruded backsheets are opening up novel circular possibilities for the solar industry, as well as driving durability and lowering costs, writes Netherlands-based materials specialist DSM.

As problems with component failure have already laid bare, there is a clear need for contract clarity at every stage of a PV project, from material and component sourcing to power purchase and operations agreements. Here, pv magazine investigates a little covered issue for module buyers, which could threaten insurance coverage and the overall success of a project further down the line.

The Indian Government plans to tender 60 GW of solar and 20 GW of wind capacity by March 2020. This would complete the planned auctions for its targets of 100 GW solar and 60 GW wind installations by 2022, leaving two years for project execution, according to an year-end review by the Ministry of New and Renewable Energy (MNRE).

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.

The iSTAR-C program of India’s International Solar Alliance (ISA) was adjudged an outstanding project during the Paris Peace Forum this month. The program is one of many ISA initiatives to develop solar resources in member countries. After the first assembly of the ISA, interim Director-General Upendra Tripathy tells pv magazine about the organization’s achievements and plans.

The first companies are demonstrating that today it can be worthwhile commercially to back electric vehicles in combination with solar generation and storage. Particularly in the case of public charging stations, solar power used for electric vehicle charging could become the basis for a profitable operator model in the future.

The research team was able to improve the cell efficiency by 2.1%. The cell silicon layer was etched on the back-side, while a a polymer light management (LM) foil was applied to the front-side of the device.

New research from institutes at the London School of Economics has found a significant gap between what countries declared they would be doing in compliance with the Paris Agreement, and what they have translated into national law three years later. As officials from around the world will flock to Poland next month to negotiate the implementation pathway of the Paris Agreement, this and other new studies draw a dark picture of current performance.
