Perovskite Solar Cell: History, Progress and Perspective
In 2012, a seminal report was published on the 9.7% efficient and 500h-stable solid-state perovskite solar cell (PSC) based on methylammonium lead iodide. Since then, power conversion efficiency (PCE) has swiftly increased to over 25% due to the unique photophysical property of halide perovskite. According to the Web of Science, more than 31,000 papers on PSCs have been published since 2012. PSC is regarded as a game changer in photovoltaics because its low-cost and high efficiency surpasses conventional high-efficiency thin-film technologies. High photovoltaic performance has been realized by compositional engineering, device architecture, and fabrication methodologies for a decade. In order to reach theoretical efficiency of over 30% and long-term stability, exquisite control of light management and photo-excited charges are required, as well as thermodynamic phase stability.This talk briefly introduces the history and progress of PSCs. At the same time, an approach toward stable and higher efficiency PSCs, the important practice of facet engineering of perovskite films, will also be discussed.

2023 Special Programs

Workshop: Ultrafast Signal Processing by Combined Photonic-Electronic Integrated Systems: Where, Why and When?

Sunday, 09 July 15:00 – 18:00
Banquet Hall 2

Ultra-fast and energy-efficient information processing is required in many applications, such as communication systems, cloud computing, artificial intelligence, smart factory, instrumentation and medical technology. Today optical and electronic circuits are still mostly separated domains. In the recent past, however, photonic-electronic integration has developed rapidly based on either Silicon photonics or Indium-Phosphide technology platforms. Such combined nanophotonic-nanoelectronic circuits and systems will significantly increase signal processing speeds and enable novel system concepts. The close proximity between optics and electronics will also reduce energy consumption and size.

This workshop investigates how combined photonic-electronic signal processing and photonic-electronic integration technologies can overcome the drawbacks mentioned above and pave the way to completely new system concepts. Presenters will discuss examples of future combined signal processing circuits, challenges and limitations.

Workshop: AI and Digital Twin for Transforming Optical Networks: What They Can and Cannot Do? - Session One

Sunday, 09 July 15:00 – 16:15
Banquet Hall 3

Digital transformation of societies requires optical communication networks to support the enormous increase of traffic with challenging service requirements in an autonomous, reliable, trustworthy, secure and sustainable manner. Moreover, the optical communication ecosystem itself is transforming from static, closed and often manually-operated, vendor-locked systems to elastic open and disaggregated optical networks. The autonomous operation of such a dynamic, multi-vendor, multi-domain and open networking infrastructure is becoming a challenging hurdle, requiring exceptional interoperability, cooperation and intelligence in various levels of its networking stack.

AI has become an inevitable tool to contribute to this transition. In addition, Digital Twins (DTs) of optical networks have attracted remarkable attention to facilitate the smooth interaction between AI and physical network entities.

This workshop offers an agora (i.e., open space) to discuss the realization of AI-assisted disaggregated optical networks, its near-term use cases and unexplored challenges. Moreover, it brings together experts to discuss the envisioned role of DTs in addressing the key issues of our industry.

The workshop is structured in two sessions and concludes with a panel discussion. 

Session One: AI for Network Automation

Automating disaggregated optical networks is an extremely challenging task, requiring powerful tools such as AI to address it. Incorporating AI-assisted solutions in the operation of the networks requires trusted and pre-trained models and real-time (on-demand) availability of telemetry data for their execution. Considering the tremendous amount of telemetry data each network element could produce and the resources required to store and process them, it is necessary to decide what to, when to and how to collect for each particular use case. Under these circumstances:

  • What are the key areas in which AI can significantly transform the status quo?
  • Will AI bring substantial benefits that justify the enormous resources required?
  • Where will we see the early adoption of AI in live optical networks?
  • What are the challenges of its adoption for disaggregated optical networks?
  • Shall we expect a cooperative eco-system where different players (vendors/operators) share/trade their data/models under pre-defined terms and conditions?
  • Could we expect a data/model marketplace among different players?

Session Two: Digital Twin for Network Transformation

DT is a multiphysics, multiscale, probabilistic, ultra-fidelity simulation that reflects the status of a corresponding physical system based on historical data, real-time sensor data and expert knowledge. DT of optical networks and network entities will greatly accelerate the interaction and convergence between the AI-assisted virtual planning platform and the physical network. The second half of the workshop reviews the recent developments of DT technology in the optical network field and examines the outlook for the optical network DT. Some of the topics to be explored include:

  • What is the status of DT technology for optical networks?
  • What are the role and requirements for the optical network DT?
  • How to model and implement DTs?
  • When do the conventional network/transmission simulators and the monitors evolve into DT?
  • When does the physical layer meet the DT?
  • What would be the role of DTs at the sub-system level?
  • How would it affect the sub-system design?

Therefore, representatives of the Optica Novel Optical Materials and Applications (NOMA) and Solar Energy and Light-Emitting Devices (SOLED) Topical Meetings are organizing a Symposium on Sustainability in Optics.

In this symposium, we will address the following topics:

  • Solar Energy — one of, if not the most important renewable energy technologies.
  • Sustainable Materials and Manufacturing — we aim to take a special look at industry.
  • Recycling — of utmost importance in a sustainable circular economy where the requirement for new planetary resources is minimized.


Joint Symposium on Neuromorphic Photonics and Optical Computing

Monday, 10 July 08:30 – 16:00

Jointly held by the Networks and IPR Topical Meetings

Integrated photonic technologies, with their tremendous potential of delivering large bandwidths and unmatched parallelization capabilities at low power consumptions, as well as their widely successful commercialization in recent years, have enabled several modern optical computing applications. In particular, neuromorphic photonics is one of the most viable and promising solutions for addressing the needs and bottlenecks of modern AI applications. Meanwhile, although very impressive R&D results have been presented within a very short period of time by various groups around the world, an abundance of challenges still remain to be solved for developing photonic devices, interconnects and large-scale integrated circuits, to enable energy-efficient, low-latency and high-speed optical-domain computing.

This symposium aims to discuss a wide variety of neuromorphic photonics and related technologies, ranging from novel photonic devices, systems, networks and applications. Existing technologies and prospects related to various aspects and different implementations of photonic neural networks (PNNs), from photonic synapses to artificial and spiking neurons and their applications, will be discussed by a diverse and international cohort of speakers from academia and industry.

Let's build some networks!

Developing a strong professional network around core topics of interest is key to both career and scientific advancement. However, in the growing digital age and rapid advancement of research, it can be challenging to establish new connections while growing existing ones.

To facilitate this, the constituent meetings of the Optica Advanced Photonics Congress (IPR, NOMA, Networks, SPPCom, SOLED) have each selected some recent Hot Topics. As with the research, these topic descriptions are designed to be crosscutting, intersecting with more than just one meeting area.

In this informal networking session, we encourage attendees to join in on a Hot Topic area connected to their research, but outside their primary meeting area. This creates an opportunity for attendees to hear new perspectives on these growing areas, meet new researchers and share their thoughts. The leadership of each topical meeting will join each Hot Topic to facilitate discussions, so make sure to drop by and introduce yourself!


  • Nonlinear Photonics and Applications
  • Quantum Photonic/Network Technologies
  • Bioinspired Optics
  • Soft Materials
  • AI/ML in Optics and Communications
  • High Capacity Transmission
  • Sustainable Photonics
  • The Role of Optics in a Decarbonized Energy System


Closing Toast

Thursday, 13 July 16:00 – 17:00
