Researchers in Singapore have created a flexible framework for designing hotspot-resistant shingled modules. Their work is claimed to be perfectly compatible with existing manufacturing techniques.

The energy company will buy panels from JinkoSolar, Risen Energy, Canadian Solar, JA Solar, GCL Integration and Longi. Elsewhere, Xinyi Solar and Golden Solar have both announced new transactions to strengthen their business.

An international research team has tested a holographic film based on prismatic concentrators that was presented by Russian scientists last year and is claimed to significantly reduce the operating temperature of solar modules, including that of thermal-photovoltaic devices. According to the new findings, the film is able to lower the operating temperature by around 3.5 degrees Celsius.

The Chinese manufacturer has launched two new bifacial products based on its n-type TOPCon 2.0 cell technology. The JW-HD156N panel has a power output of 615W, a front side efficiency of 22% and is intended for utility scale projects. The second product, called JW-HD108N, is an all-black panel with a power rating of 425W, for the residential segment.

Israeli researchers have tested organic PV modules to power polytunnel greenhouses and have found that they might offer advantages over conventional crystalline silicon, despite their lower efficiency rates. They have lower operating temperatures but are subject to degradation, due to the mechanical stress caused by the wind-induced movement of tunnel sheeting.

Scientists in China have developed a cell with an open-circuit voltage of 0.673 V, a short-circuit current of 23.7 mA per cm2, and a fill factor of 66.8%. They improved the quality of the antimony selenosulfide films by using alkali metal fluorides.

NASA sent the world’s most powerful telescope into space on Dec. 25. It deployed and powered a related PV array 30 minutes after launch.

Solar manufacturer Zhonghuan Semiconductor has further decreased the prices of most of its PV wafers, while Beijing-based project developer Jingneng Clean Energy Co., Ltd (JNCEC) announced on Wednesday that its board has approved an investment plan for the construction of a 1GW renewable energy project in Inner Mongolia.

The lithium-ion battery producer began manufacturing activities at its new factory in Ningde city, Fujian Province. Aiko Solar has also secured 4,515,000,000 wafers for the next three years through three different supply deals.

Scientists at the Nankai University in China have provided a comprehensive overview of current research on silicon heterojunction-based tandem solar cells (SHJ-TSCs) and shared their expectations of future developments in this field.
