The virtual 7th Asia-Pacific Climate Change Adaptation Forum was hosted in March by Japan’s Ministry of the Environment, together with the Asia Pacific Adaptation Network (APAN) Secretariat. The theme was “Enabling Resilience for All: The Critical Decade to Scale-up Action” with the goal of formulating National Adaptation Planning for science and technology, and energy and fiscal policies that consider the interlinkages between climate change, health, and biodiversity. These nature- and ecosystem-based policies will serve as the basis for the Asia-Pacific region’s contributions to the “Leaders’ Summit on Climate” in the United States; the United Nations Biodiversity Conference (COP 15) in Kunming, China; and the United Nations Climate Change Conference (COP 26) in Glasgow, United Kingdom.

Owners and operators of energy storage systems, as well as investors, need transparent ways to evaluate battery performance. They need certainty that the selected batteries for their ESS projects will perform reliably, have predictable life expectancies, and meet projected revenue and contractual obligations over their lifetimes. The economic viability of entire projects depend on this confidence, writes Michael Kleinberg of DNV.

This year will witness the end of the French program for PV tenders known as “CRE4”, which began in 2016. To date, they have enabled over 7.2 GW of solar capacity to benefit from a subsidized tariff (feed-in tariff or feed-in premium). A few months before the last CRE4 tenders and the launch of the PPE2 (or CRE5), Finergreen evaluates their impact on the French solar industry.

The performance ratio test is at the core of the handover from EPC to owner. Yet sometimes, even when best practice is applied – and without particularly demanding guaranteed values to be achieved – these tests fail good projects. This can lead to costly delays and wasted effort spent trying to find issues that might not exist. Everoze Partner Dario Brivio reviews the likelihood of this happening and considers ways to increase confidence in the precision of such tests, based on recent independent analysis of real-world projects.

The PV industry has experienced several rounds of price increases since the second half of 2020, from polysilicon to materials such as PV glass and films. Between July 2020 and February 2021, prices quoted for 3.2 mm and 2 mm glass surged by more than 60% per square meter. Prices for EVA and POE encapsulant films skyrocketed by more than 40% and 10%, respectively. Prices for silver paste also rose 7%, and have since remained stubbornly high. PV InfoLink Chief Analyst Corrine Lin examines the impact of silver’s recent price turbulence on PV cell manufacturing.

Scientists in the U.S. demonstrated a sodium-ion battery with no anode, that retained 99.93% of its initial capacity per cycle. Their design was able to overcome many of the stability issues associated with using ‘pure’ alkali metals in batteries, thanks to carefully minimizing water content in the liquid electrolyte.

The cell features an open-circuit voltage of 1.1 V and a short-circuit current of 26 milliampere per cm-2, which the research team described as the best performance for an inverted perovskite cell based on single-crystal methylammonium lead triiodide. The device was built with a microns-thick absorber layer placed between an electron transport top layer and a hole-transport bottom layer.

Scientists in China have developed a large-area perovskite solar panel by utilizing diphenyl sulfoxide (DPSO) as an electron acceptor. The device was fabricated via slot-die coating, and featured a parallel-interconnection architecture.

Scientists in China took a closer look at the role of defects in limiting the performance of perovskite solar cells, demonstrating a screening effect that could be tuned to make material defects “invisible” to charge carriers, greatly improving cell performance. Using this approach they demonstrate a 22% efficient inverted perovskite solar cell, and theorize several new pathways to even higher performance.
