In addition, I was also awarded the ACAP II Fellowship in 2024-2025 in recognition of my research contributions to photovoltaic technologies.

My Research Activities

Reliability assessment of advanced silicon solar cell technologies, including HJT, TOPCon, and PERC architectures

Investigation of degradation mechanisms in silicon solar cells induced by environmental stressors such as moisture, light exposure, and corrosive agents

Development of rapid, cell-level diagnostic testing to accelerate evaluation of degradation pathways and predict long-term performance

Analysis of PV module bill of materials (BOM) degradation such as glass, Encapsulant (EVA, POE, EPE..), soldering flux , with a focus on material interactions and their impact on module stability and reliability

My Research Supervision

Supervision keywords

silicon

encapsulant

inverted polymer solar cells

Areas of supervision

I have co-supervised five PhD students on photovoltaic (PV) reliability projects, with one student having successfully completed their PhD and subsequently appointed as a postdoctoral researcher managing several of our industry collaboration projects. In addition, I have supervised five master's thesis students, all focused on PV reliability and the development of rapid cell-level testing methodologies. These projects have directly contributed to advancing diagnostic tools and understanding of degradation mechanisms in commercial PV technologies.

Annealing prior to contact firing: A potential new approach to suppress LeTID
In this work, we introduce a new approach to suppress light and elevated temperature-induced degradation (LeTID) by applying a pre-fire annealing step using rapid thermal processing (RTP) and discuss the impact of this process on the evolution of bulk and surface lifetime components. We...

Eliminating light- and elevated temperature-induced degradation in P-type PERC solar cells by a two-step thermal process
Light- and elevated temperature-induced degradation (LeTID) can have a severe impact on the carrier lifetime of silicon substrates used in solar cell production and thus remains a crucial challenge for manufacturers. In this work, we introduce a two-step annealing process to mitigate Le...

Assessing the Impact of Thermal Profiles on the Elimination of Light- and Elevated-Temperature-Induced Degradation
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 of the degradation is yet to be confir...

Controlling Light- And Elevated-Temperature-Induced Degradation with Thin Film Barrier Layers
In this article, we investigate the extent of lifetime degradation attributed to lightand elevated-temperature-induced degradation (LeTID)inp-type multicrystalline silicon wafers passivated with different configurations of hydrogenated silicon nitride (SiN x :H) and aluminum oxide (AlO ...

Impact of Dark Annealing on the Kinetics of Light- and ElevatedTemperature-Induced Degradation
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 that defect kinetics can be modulated ...

Evaluating the Impact of Sin Thickness on Lifetime Degradation in Silicon
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 suggest the involvement of hydrogen i...

Hydrogenation of Dislocations in p-Type Cast-mono Silicon
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 industrial production of cast-mono solar ce...

Investigation of temperature and illumination dependencies of carrier-induced degradation in p-type multi-crystalline silicon
Carrier-induced degradation (CID) in multi-crystalline silicon (mc-Si) solar cells, often also referred to as Light- and elevated Temperature-Induced Degradation (LeTID), significantly affects the performance of mc-Si PERC cells when they are subjected to light or carrier injection. How...
