JA Photo voltaic has disclosed that it has achieved a record-breaking open-circuit voltage for a photo voltaic cell utilizing tunnel oxide passivated contact (TOPCon) expertise. The Chinese language PV module maker, based also in Arizonafamous that the discovering was independently confirmed by Germany’s Institute for Solar Energy Research in Hamelin (ISFH). JA Photo voltaic reported that its Bycium+ photo voltaic cell had achieved an influence conversion effectivity of 26.07%, an open-circuit voltage of 748.6 mV, a short-circuit present of 13.71 mA, and a fill issue of 83.82%. This milestone not solely highlights TOPCon expertise’s monumental potential, but in addition units a brand new normal for the event of crystalline silicon PV cells.

“This milestone with our Bycium+ cell is not just a testament to JA Solar’s commitment to technological innovation but also a contribution to advancing the PV industry as a whole,” mentioned Aiqing Yang, Government President of JA Photo voltaic. “By setting a new benchmark for TOPCon cell open-circuit voltage, we aim to inspire broader progress across the industry, driving the development of high-performance, cost-effective PV solutions that accelerate the global transition to clean energy.”

The enhancement of PV cell effectivity is usually divided into two areas: optical acquire and electrical acquire. “Electrical gain is driven by reducing recombination losses and contact resistance. Open-circuit voltage is directly linked to recombination and is a key indicator of a cell’s performance. Higher open-circuit voltage leads to better efficiency and affects the temperature coefficient of PV modules.”

Passivation approach is vital for growing open-circuit voltage and cell effectivity by reducing inside recombination losses and permitting extra electrical vitality to be recovered. JA Photo voltaic has persistently refined the passivation construction of its TOPCon cells to scale back floor, bulk, and metallic recombination. By integrating improvements in metallization, new supplies, and processes, JA Solar broke the open-circuit voltage file. This innovation brings TOPCon expertise nearer to its theoretical effectivity restrict, therefore supporting the PV business’s future progress.

When Ja Photo voltaic introduced its manufacturing to the US, Arizona was happy. The Chinese language photo voltaic powerhouse matches completely into the state’s ambitions and provided the neighborhood 600 jobs. “Arizona is proud to welcome JA Solar’s first US manufacturing facility to Phoenix,” mentioned Arizona Governor Katie Hobbs, who lists “water and environment” amongst her prime priorities on her workplace’s official web site. “There’s no better place in the world for sustainable industries like solar, and we are excited to see this facility add to Arizona’s clean energy reputation.”

“We are very excited to be able to set up the first US solar module manufacturing facility in Arizona to provide our customers in the US the flexibility and ease of access to (our) high-performance PV products,” mentioned Aiqing Yang, President of JA Photo voltaic. “(Thanks to) all the partners in Arizona, especially the ACA, GPEC, and the City of Phoenix, for their great support and tremendous assistance during the entire process of site selection and space leasing in preparation to establish the manufacturing facility. Solar is a critical part of renewable energy, and we are thrilled to be a part of the effort to meet the goal of carbon neutrality by 2050 in the US.”
