Light- and elevated temperature-induced degradation (LeTID) has been extensively studied on p-type silicon materials with increasing evidence suggesting the involvement of hydrogen. Recent findings identical phenomenon in n-type wafers have further opened up new areas understanding into inherent behavior root cause defect. In this work, we compare LeTID observed both p- under dark illuminated annealing conditions, highlighting previously unobserved similarities defect formation recovery...

Abstract High‐efficiency silicon‐based tandem solar cells will likely drive the push towards terawatt (TW) scale PV manufacturing on pathway to net zero emissions by 2050. In this work, we provide a comprehensive analysis of material consumption and sustainability issues for future cells. First, analyse sustainable capacity variety potential candidates top cell in cell. We show that III‐V, CIGS CdTe are not suitable support TW‐scale manufacturing. Perovskites thus present most approach, as...

Abstract As PV manufacturing heads towards the multi‐TW scale, it is required to carefully evaluate a wide range of concepts including not only efficiency and cost but also material consumption ensure sustainable technologies. The rapid growth could significantly increase demand for several materials in solar cells such as silver, aluminium, copper even silicon, thereby causing dramatic price fluctuations. Furthermore, capacity would be at risk being limited by supply some scarce metals,...

Abstract Photovoltaics (PV) is one of the most effective and necessary energy sources to mitigate climate change. The broad electrification scenario projects PV market grow from 1 TW in 2022 over 63 2050. While increasing production will significantly reduce emission intensity electricity generation, it still important minimise overall environmental impact such a large industry. In this study, we investigated greenhouse gas (GHG) emissions 30 MW plant using life cycle assessment (LCA). Based...

Abstract In this work, the efficiency potential of fully screen-printed passivated emitter and rear contact (PERC) solar cell structure is investigated via numerical simulations. A series improvements optimizations are performed on bulk quality, properties metallization PERC cells based experimental results obtained in both industry laboratory environments. With significantly improved surface passivation we find that carrier recombination losses at metal/silicon interface will impose a...

As the photovoltaics industry approaches terawatt (TW) manufacturing scale, consumption of silver in screen‐printed contacts must be significantly reduced for all cell architectures to avoid risks depleting global supply and substantial cost inflations. With alternative metallization techniques (e.g., plating) facing their own challenges mass production, advancements mainstream screen‐printing technology accelerate pace reductions are urgently needed. This work presents a silver‐lean contact...

A critical concern for the photovoltaics (PV) industry is ensuring sustainability at terawatt (TW) level. We are now risk of entering a phase unsustainable resource use, despite key goal to provide 'renewable' and 'sustainable' energy. Estimated silver (Ag) reductions as in ITRPV projections not sufficient avoid significant increase overall consumption. Targets PERC 2030 would result using 50% global supply ~1.7 TW, which still low scale expect demand price. Predicted Ag consumption suggests...

The global cumulative photovoltaic (PV) installed capacity is now over 1 TW. While this an impressive amount of PV growth, it contributes less than 3% total electricity generation and, therefore, requires significantly more to decarbonize the sector completely. In order achieve decarbonization sustainably, all factors must be considered, including extraction and purification abundant materials. Based on conservative ambitious future production scenarios learning rate (LR) for material...
