The Mechanics of Light Elevated Temperature Induced Degradation(LeTID) on PERC Module: A Review
Jaljalalul Abedin Jony,Hasnain Yousuf,Muhammad Aleem Zahid,산얄 심피,Muhammad Quddamah Khokhar,Polgampola Chamani Madara,Yifan Hu,Mengmeng Chu,김영국,Suresh Kumar Dhungel,Junsin Yi 한국전기전자재료학회 2024 Transactions on Electrical and Electronic Material Vol.25 No.3
Passivated emitter and rear contact (PERC) cells are fi nancially commanding and rapidly increasing PV system in the energy market. Its effi ciency decreases over time because of the Light-Induced degradation (LID) that follows countlesshours of exposure to light (above 50 oC temperature), and collectively is termed as Light and Elevated Temperature Induced Degradation (LeTID). Every PERC solar cell module experiences the LeTID eff ect signifi cantly. Excessive hydrogen injection into Si bulk creates the atomic-level defect structure, which is mainly guilty for the LeTID. Therefore, the normal lifetime of PERC modules has become less, and ultimately levelized cost of electricity (LCOE) of installed systems is increasing. All c-Si types of PV devices are degraded by 5%, whereas the PERC module is degraded by up to 10% due to LeTID. Even, 16% power loss took place due to this kind of degradation, though an effi ciency of 23.6% has been recorded for the PERC solar cells. The mono-crystalline Si solar cell module degraded (2-3.6) % while multi-Si solar cells module can be degraded up to (3.8–7.5) %. This study has covered the introduction and characterization of the LeTID, exploring the infl uencing factors for LeTID and mitigation techniques of decadence. LeTID on PERC module is altered depending on the variations of weather and the variety of cells used in PERC modules, which have been reported in this review. These insights will be helpful in fi nding a better understanding of the LeTID eff ect on the PERC module.

In the realm of solar energy technology, exploring hafnium oxide (HfO2) in Tunnel Oxide Passivated Contact (TOPCon) solar cells is pivotal. This study delineates HfO2's evolution from semiconductor applications, highlighting its crucial role in enhancing TOPCon solar cell performance. Utilizing ATLAS Silvaco software, the study anticipates a 21.3% increase in charge carrier lifetime through optimized HfO2 layers, addressing challenges in interface engineering and scalability. Innovative research integrates hafnium oxide (HfO2) into TOPCon solar cells, marking a leap in photovoltaic technology. Utilizing ATLAS Silvaco simulations, it shows that HfO2 layers can significantly enhance cell performance, increasing charge carrier lifetime by 21.3% and potentially boosting efficiency by 25%. This underscores HfO2's advantages, like a higher dielectric constant and thermal stability, in improving solar cell efficiency and durability. Future efforts target refining deposition processes, projecting a 25% boost in overall power conversion efficiency (PCE). Emphasizing HfO2's significance in solar cell technology, this research contributes to global sustainable energy initiatives. Integrating HfO2 in TOPCon solar cells signifies a key achievement in harnessing clean, renewable energy. Upcoming research focuses on experimental validation, interface engineering, optimization, stability assessments, scalability, and collaborative studies, aiming to leverage HfO2's potential for elevating solar energy conversion technologies.
