The minds behind the success of our research
Professor Ziv HAMEIRI
Why is your research important?
All the different aspects of my research aim to achieve the same goal: Making photovoltaics cheaper. I truly believe that solar energy (and a vegetarian diet) is the only way to save our planet. Through my research, I am trying to do my part to save the world faster.
What do you like about research?
The fact that my passion is also the main way to save the world. Working with very smart and creative people. Being challenged all the time. Discovering something that did not exist before.

Why is your research important?
Characterization is essential for understanding the performance limiting factors for photovoltaic devices, not only for research but also for industry. Defects stimulate the recombination of photo-generated charge carriers. Therefore, controlling the defects is essential for improving the performance of photovoltaic devices. The continuing improvement of photovoltaic materials and device architectures also calls for new characterization techniques.

Why is your research important?
Understanding the dynamics of complex physical systems is difficult. But the more you understand, the better your predictions of the future become. And who doesn't want to predict the future?
Why do you like research?
It is far more rewarding to explore the uncertain and discover the unknown than to shelter in the safety of established knowledge. Research improves your odds...

Improving the understanding of the materials’ electrical properties, their temperature dependence and their impact on solar cell performance and energy yield in the field.
Why do you like research?
It always surprises me! Nothing will go according to plan and your expectations.
Dr Robert LEE CHIN
Why is your research important?
Helps the fundamental understanding of the nature of defects in solar materials. Luminescence in general is a versatile technique because it can be used to quantify losses from defects in solar cells at any stage of fabrication (precursors to cells) and any type of solar cell absorbers (from silicon to perovskites, III-V materials, kesterites). When combined with a microscope setup and different detection methods, such as spectrally-resolved and injection-dependent, you can extract rich information about the...

Why is your research important?
Crystalline silicon solar cells with passivated contacts will be one of the most dominant and widely produced solar cell technologies in the coming decades. The development of high-efficiency passivated contact devices – and the next-generation materials needed for them – will drive the levelized cost of electricity to new lows and further cement photovoltaic energy’s place as the most cost-effective form of electricity generation we have available.
Dr Tien-Chun WU
Why is your research important?
Reliable forecasting and coordination of utility-scale renewable energy generation and EV-grid interactions pave the path towards energy-efficient net-zero carbon emissions target. The development of scalable spatiotemporal multimodal deep learning models would achieve these capabilities and help policymakers address the imminent climate crisis with quantifiable recommendations.

Anh Huy Tuan LE
Why is your research important?
Although transition metal oxides (TMO)-based solar cells are very promising with regards to device efficiency, TMO passivating contacts have been limited to small devices using deposition techniques that are impractical for industrial applications. My research is to develop TMO passivating contacts using common industrial techniques that can be easily integrated into existing manufacturing capacity. Furthermore, I investigate passivating contacts using advanced characterization techniques to gain a better understanding and more insights...
Simon ZHANG
Why is your research important?
My research has two unifying themes: (1) introducing established characterisation techniques to novel fields within photovoltaics; (2) validating photovoltaic technologies for long-term field conditions. The former, under which both of my Suns-Voc projects fall, fills a gap in characterisation method development for different photovoltaic materials. It therefore has high potential to provide novel findings from previously unconsidered perspectives. My field-oriented studies aim to ensure that state-of-the-art technologies developed in the...

Why is your research important?
Designing high efficiency solar cells at low cost and high stability contributes to numerous environmental and social benefits, such as producing far less global warming emissions, and improving standards of living in areas with the lack of power infrastructure. Among various types of solar cells, perovskite based tandem cells has been known as a promising photovoltaic technology toward achieving these goals. That’s why I am motivated to work in this area. My research focuses on the development and the electro-optical modeling of perovskite-based...

Maysa Jehad SARSOUR
Why is your research important?
The study of photovoltaic (PV) system reliability provides insight into true PV power output over the project lifetime. Accurate reliability estimates result in better bankability. Therefore, it is important to proactively detect and predict faults and PV system degradation to maintain performance. My research will utilise machine learning algorithms to classify and proactively predict faults and degradation of utility-scale PV systems.
