Modules & Upstream Manufacturing

The Düsseldorf Regional Court has agreed rivals of the Korean manufacturer illegally used its patented passivation technology. The judges granted Hanwha Q-Cells an injunction which requires Jinko, REC and Longi to retrieve all modules featuring the patented technology distributed in Germany since late January last year. Hanwha can also opt to have the offending products destroyed.

A team of researchers led by Nanchang University in China trialed a polymer based hole transport layer to flexible perovskite solar cells, using a glue to attach it to the active perovskite. The team was able to assemble the 19.87%-efficient cells into a small flexible module suitable for wearable solar applications, and says its design was inspired by the structure and movements of human vertebrae.

Despite the challenges to both the manufacturing and shipment of its products during the period, JinkoSolar today reported that it shipped 3.4 GW of modules in the first quarter of 2020, bringing its revenue for the quarter just over the billion dollar mark.

PV manufacturers unable to live with proposed new quality guidelines and project developers alike are set to be squeezed out by the state in the world’s biggest solar market, according to Frank Haugwitz, who has compiled a market update as preparations for the next five-year plan gather pace.

From the acquisition of IP to commercialization, the PV industry has witnessed a rapid rise of gallium-doped silicon. Researchers are testing the resulting cells’ stability while industry has begun the manufacturing phase. All this leads to a key question: Will gallium doped silicon solar modules will be the next big thing?

European scientists have developed mini modules with an active area of 14 cm² and a 3.68% efficiency rating. The panels also have a self-adjusting feature that can help to mitigate the amount of light when they are exposed to full sunlight, or to the temperatures of buildings with large windows and/or glass facades.

Longi will build 600 MW of unsubsidized PV in Datong, Shanxi province. The Shanghai Development and Reform Commission, meanwhile, has unveiled new 2020-21 FITs. Yingli is undergoing restructuring, while Trina had a solid listing debut in Shanghai.

Researchers in Malaysia have developed a new, cheaper method to assess PV cooling techniques. Designers and manufacturers of PV cooling systems could follow the parameters of the new approach to evaluate the performance and bankability of their own devices, the scientists claimed.

A new report from Rocky Mountain Institute in the U.S. explores the need for companies to disclose information about greenhouse gas emissions throughout their supply chains, and the most effective ways to do this whilst ensuring consistency and comparability of collected data across multiple industries.

Researchers at the Massachusetts Institute of Technology have developed a new approach to improve the electrical properties of monolayer graphene grown by CVD that could be used in the production of more efficient and stable ultra-light organic cells. They used parylene to develop transparent graphene electrodes through a roll‐to‐roll transfer technique.
