The photovoltaic industry is developing rapidly and faces challenges in the long-term availability of key resources such as silver. The global photovoltaic industry consumed about 13% of the global annual silver production in 2022. Copper and aluminum are potential materials to replace silver. Coppe...

Interdigitated back contact (IBC) solar cells have the potential for high efficiency due to their front-electrode-free design and double-sided passivated contact characteristics. However, the traditional IBC cell manufacturing process is complex, involving multiple doping and electrode patterning st...

HJT solar cells have achieved passivation contact on the front and back surfaces, so they have obtained a higher open circuit voltage, which is significantly higher than TOPCon cells and PERC cells. However, there is a serious parasitic absorption in the amorp...

TOPCon solar cells with ultra-thin silicon oxide SiOx film and phosphorus-doped polysilicon Poly layer have a theoretical efficiency limit of up to 28.7%, becoming a hot research technology in the industry. TOPCon cells show superior passivation quality at the metal-silicon conta...

Atomic layer deposition (ALD) technology is widely used in micro-nano electronics, energy storage and other fields due to its excellent controllability, uniformity and conformality. Under the conditions of 200°C and 60 rpm, trimethylaluminum and water were used as precursors to form high-quality...

Wide bandgap metal halide perovskites are ideal semiconductors for use in combination with silicon stacks to achieve power conversion efficiencies (PCE) exceeding 30% while reducing costs. However, wide bandgap perovskite solar cells are fundamentally limited by light-induced pha...

The energy conversion efficiency of perovskite solar cells (PSCs) has increased from 3.8% to 25.2% and beyond in 10 years, but their commercialization is limited by instability. Researchers have developed a low-cost polymer/glass tandem packaging solution that enables PSCs to pas...

The development of BC cells has reduced the cost of photovoltaic power generation, but the diversification of application scenarios has put forward higher requirements for solar cell technology. Studies have found that the contact resistivity of HBC solar cells has a great influence on cell per...

Solar energy has attracted attention as a future energy source. Among the several BC cells (HPBC, TBC, HBC) for next-generation products, HPBC is a direction for the development of solar cell technology. HPBC cells combine the advantages of passivated emitter and back surface pas...

The percentage of PV module output power to the total power of the cell (CTM) is an important parameter to measure the degree of power loss in module packaging. The promotion and application of high-efficiency cells such as PERC, TOPCon, HJT and XBC cells have made new packaging...

The solar photovoltaic industry is seeking to improve module performance through innovative manufacturing processes, new materials, solar cell designs and module configurations. SHJ solar cells have advantages such as high PCE, simplified manufacturing processes and low manufacturing tempe...

As the mainstream solar energy core conversion technology in the market today, the performance optimization of crystalline silicon solar cells depends on the precise design of the structure and the monitoring of the manufacturing process, among which the PN junction doping contro...
