Chinese solar module producer Jolywood has introduced a new module high efficiency bifacial module series called Niwa® Super with power ratings ranging between 570 W and 615 W.
At the recently concluded SNEC 2020 in Shanghai, China, Jolywood unveiled 3 products under the Niwa brand – Niwa Super, Niwa Pro and Niwa Black. All three use the latest generation of the company's N-type TOPCon cell technology and have a module efficiency of 22.1%.
For these modules, Jolywood has deployed large-size silicon wafers, 11 busbars, half-cells and a nano-alloy transparent backsheet. The panels weigh 12.1 kg per m2, a fact that the company argues lowers the installation cost while expanding large modules into the rooftop segment and other applications.
As the name suggests, the Niwa Black modules are all black using black mesh backsheets and N-type silicon, TOPCon cells, multi-busbar and half-cell technology. According to Jolywood, these modules are not shiny as the cell-coating used is a multilayer anti-reflection film composed of 3 different dielectric layers matched with a special coated glass.
"This is our new Niwa second-generation product which has made significant improvements and enhancements in terms of cell efficiency and module technology compared to the previous generation of Niwa products – the cell efficiency increased from 23.2% to 24.5%, and the mass production efficiency averages 24%," said Jolywood's Deputy General Manager Dr. Zhifeng Liu, adding, "Our second-generation Niwa products have the core advantages of "three highs and three lows", namely high efficiency, high bifaciality, high reliability, low degradation, and no LID /LeTID, low temperature coefficient." This is the top photovoltaic module on the market in the future, he emphasized.
Under its existing cooperation with the Belgian Microelectronics Research and Development Center (IMEC) since 2016, Jolywood said it will research further on N-type bifacial PV technology (see 23.2% Efficiency For Bifacial N-PERT Solar Cells).
Currently, the Chinese company, which is a leading producers of n-type solar cells/modules and also a global leader in module backsheets, has 2.1 GW of N-type bifacial solar production capacity and 3 GW of module production capacity currently.
