Sodium Diffuses from Glass Substrates through P1 Lines and
In this work, we use complementary microscopy and spectroscopy techniques to show that Na diffusion occurs in the fabrication process of PSMs. Na diffuses vertically inside

Under outdoor conditions, PV modules often experience high system voltages, leading to the migration of sodium ions. This movement is primarily driven by an electric field
Abstract: Sodium induced shunting continues to be a challenging issue in crystalline Si solar modules. Potential-Induced Degradation of the Shunting type (PID-s) has
It is found that Na+ ions are highly detrimental to the HJT cell architecture. When the front side is exposed to Na+, the series resistance (Rs) increases, likely due to corrosion of the finger
Soda-lime glass with a concentration of sodium around 13–15% is widely used both as cell substrate and as front layer in PV modules. Glass is not a static material and Na
In this work, we use complementary microscopy and spectroscopy techniques to show that Na diffusion occurs in the fabrication process of PSMs. Na diffuses vertically inside P1 lines and
The sodium selenide formed at the front surface of the CIGS can act as a Se source to promote the formation of larger CuSe 2 grains, resulting in large CIS grains near the
University of New South Wales researchers investigated the impact of sodium-induced degradation in heterojunction solar cells under accelerated damp-heat testing.
Often it is assumed that sodium found in PID-s affected cells originates from the cover glass used for photovoltaic modules. In this
Different possibilities in sodium ion migration control are presented, considering the influence of glass composition on sodium diffusion & its chemical potential as well as passivation of sodium
This paper describes the influence of sodium on the structural and photovoltaic properties of low temperature processed CdTe solar cells and shows the reasons for
At these high voltages, leakage currents drive sodium out of the glass at the front of the panels, through the polymer encapsulant, and into the sensitive electronics at the core.
The alkali elements in soda-lime glass (sodium, calcium, potassium, and magnesium) can seep out of the glass and impact thin-film solar cells (especially under thermal load or applied voltage).
The sodium selenide formed at the front surface of the
