Light and elevated-temperature-induced degradation (LeTID) is a well-known phenomenon that reduces the bulk lifetime in silicon wafers. The cause of this degradation mechanism is still under investigation. However, a wide range of empirical trends th

In this article, we investigate the extent of lifetime degradation attributed to light- and elevated-temperature-induced degradation (LeTID) in p- type multicrystalline silicon wafers passivated with different configurations of hydrogenated silicon n

There has been continuous effort to understand the cause of light- and elevated-temperature-induced degradation (LeTID) in silicon solar cells; however, the actual origin of the defect is still under investigation. Multiple reports in the literature

Light- and elevated-temperature-induced degradation (LeTID) in p-type multicrystalline silicon has a severe impact on the effective minority carrier lifetime of silicon and remains a crucial challenge for solar cell manufacturers. The precise cause o
Hydrogen has been long known for its ability to passivate defects in silicon devices. However, multiple recent studies on understanding the mechanism behind light- and elevated temperature-induced degradation (LeTID) have proposed that hydrogen plays

Light-induced degradation (LID) and light- and elevated temperature-induced degradation (LeTID) are well-known degradation mechanisms in crystalline silicon (c-Si). PERC cells, which are currently the dominant solar cell device structure, have shown

Light- and elevated-temperature-induced degradation (LeTID) has been shown to have a significant detrimental impact on p-type multicrystalline silicon solar cells and, in particular, on passivated emitter and rear cells. Previous studies have shown t

Cast- or quasi-monocrystalline silicon wafers are a potential source of low-cost material in the production of crystalline silicon solar cells. Variations caused by dislocation clusters across the cast-mono ingots have been a roadblock for the indust

Hydrogen released from surface passivation layers during high-temperature firing plays a crucial role in surface and bulk defect passivation, particularly in multicrystalline silicon solar cells. However, recent studies have identified hydrogen as a

This paper discusses the role hydrogen plays in degradation of silicon solar cells and modules. Slightly unorthodox, it presents a high level view of the latest research findings and theories of Professor Stuart Wenham before he suddenly passed away.
