Manufacturing

A new report form analysts at IHS Markit notes that the market for module-level power electronics (MLPE) grew by 33% between 2019 and 2021, with around one-third of new residential solar installations now taking advantage of MLPE’s promise of improved safety, energy yield and fault detection. And with smaller, distributed generation systems expected to represent 43% of global PV installations between now and 2025, the opportunity for MLPE will only get larger.

In a study that began in 2016, US scientists purchased 834 PV modules, representing seven manufacturers and 13 module types, and installed them in various climate conditions to observe their performance over time. The results show that, while plenty of opportunities still exist to extend module lifetimes and reduce performance loss in the field, reductions in the manufacturing cost of PV have not come with an increase in their degradation rate.

Laser contact opening (LCO), a standard process in PERC cell production, has seen little market development in the past few years. Stiff competition from equipment suppliers in Asia, combined with the fact that most new n-type manufacturing doesn’t make use of LCO, has kept the level of interest here quite low. However, as the PV research community increases its focus on reducing silver consumption, new approaches to cell contacting and metallization provide impetus for a second look at laser processing.

REC, a Norwegian solar panel specialist, will exhibit the latest module in its award-winning REC Alpha line at the Renewable Energy India (REI) exhibition in September. It will also join forces with its new owner, Reliance Industries Ltd., to recruit new talent for a planned solar gigafactory in India.

Sunora Solar’s new 144-cell solar module is available with power outputs ranging from 520 W to 550 W and a power conversion efficiency of 20.18% to 21.03%.

Adani Solar, which has 3.5 GW of PV cell and module production capacity, has selected Roofsol Energy as a partner for the retail distribution of its solar panels in Maharashtra. 

Scientists from France’s CEA-Ines developed a 400 W micro-inverter with a power density of 1.1 kW/L and an efficiency of 97%. The device utilizes GaN 600V diodes and power transistors developed by CEA’s electronic branch CEA-Leti.

Manufacturers have until August 16 to submit bids for the supply of 3 million multi-crystalline silicon solar cells featuring five bus bars. The cells are required in the peak power rating of 4.68 W and 4.63 W.

An international research group has reconstructed the trajectory of p-type wafers in the heterojunction solar cell segment and has identified the lack of knowledge about boron-oxygen related light-induced degradation (BO-LID) as the main cause for the limited adoption of these wafers and the success of their n-type counterparts. According to the scientists, however, there is still big room for improvement for p-type technologies in heterojunction cells.

The urban mining startup has set up an R&D and innovation center focused on improving the efficiency and yield of its chemical-free technology for extracting valuable materials from dead lithium batteries. It will ramp up the facility to double it up as a fully operational metal extraction unit by the end of December.
