Manufacturing

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.

Visaka Industries’ patented Atum solar roof will cover a 4,200 sq.ft area and produce 70 kW of power to run the lab at Anant University’s Ahmedabad campus.

USA-headquartered Enphase manufactures microinverters in India from Finnish company Salcomp’s plant in Chennai.
