Devoted to the “inexperienced manufacturing idea,” Tongwei Photo voltaic offered its newest modules on the sixteenth SNEC PV POWER EXPO held in Shanghai, China.
The photo voltaic business is at the moment experiencing chaos resulting from variations in silicon wafer sizes, module sorts, and know-how strategies, and on this context, n-type modules are rising in reputation. In recognition of the improved efficiency worth of the know-how, Tongwei Photo voltaic unveiled two new merchandise: the TNC-182 module with optimized measurement and rectangular silicon wafer cell know-how and the silver-free 210-THC modules. Each newcomers take pleasure in larger energy with decrease balance-of-system (BOS) and levelized value of vitality (LCOE).
Tongwei’s present pilot-scale manufacturing line for the independently developed plasma-enhanced chemical vapor deposition (PECVD) TNC (Tongwei N-passivated Contact Cell) know-how has achieved an effectivity of 25.7%. When it comes to mass manufacturing, the conversion effectivity of TNC cells exceeds 25.5%. TNC cells have excessive bifaciality, ultra-low attenuation, improved temperature coefficient, and an fascinating weak mild response. Tongwei Photo voltaic’s present 182 mm, 72 half-cell module has an influence of 588 W, which is 25-30 W larger than PERC, and 10% larger in bifaciality. The corporate’s new TNC-182 evolves the 182-72 model and designs for optimum cell and module measurement. The ability of recent variations of the module is additional elevated by 25-30 W and might now exceed 600 W.
Tongwei Photo voltaic has been engaged on THC know-how since 2018, and in March 2023, the mass manufacturing effectivity of Tongwei’s first GW-level manufacturing line in China reached a stage of 26.18% (confirmed by ISFH). The newly unveiled 210-THC modules have many technological breakthroughs, together with the adoption of silver-free know-how, ultra-thin silicon wafer know-how, bifacial microcrystal know-how, high-performance goal doping, and lightweight injection . Changing silver with copper electroplating additional narrows the associated fee hole with PERC modules. The brand new 210-THC module sequence of Tongwei Photo voltaic has a decrease temperature coefficient and better bifaciality, which may enhance energy technology and obtain a decrease LCOE. Tongwei is anticipated to comprehend large-scale manufacturing of its THC modules quickly.
In keeping with the worldwide purpose of “carbon neutrality,” Tongwei Photo voltaic is additional increasing manufacturing capability and cargo targets, striving to attain 300,000 tons of shipments of high-purity crystalline silicon, 70 GW of cell shipments (together with self-use), and 35 GW of module shipments.
Tongwei Photo voltaic’s module manufacturing capability is anticipated to succeed in 80 GW by the top of 2023.
