Prof. Atsushi Masuda

Program Chair of PVSEC-33

The characteristic themes of PVSEC-33 are “extension” and “integration” for the new era of photovoltaics. 
 
Area 1 and area 2 cover the theme of “extension”.
 
Area 3 and area 4 are based on the theme of “integration”. Instead of separate sessions for different materials systems or for cell- and module-scale technologies, we wish integrate common topics from different fields into shared sessions to facilitate the exchange of ideas.

Area 1 focuses on topics necessary for the continued long-term success of the photovoltaic industry and extension of the industry towards a 100% renewable energy and carbon neutral society. Sub-area 1-1 focuses on the political, governmental, and financial solutions for future PV deployment and strategies for environmental sustainability and social responsibility. Sub-area 1-2 focuses on energy management technologies, including supply-demand balance and forecasting.
 
Area 2 focuses on the extension of photovoltaic technologies to new applications. Sub-area 2-1 “Solar to X” focuses on the development of photovoltaic technologies for the conversion of solar energy to chemical energy.  In sub-area 2-2 and the special sessions, we discuss key technologies for early achievement of carbon neutral and zero-emission society such as ZEB, ZEH, BIPV, and VIPV.
 
Area 3 focuses on established wafer-based Si, high-efficiency III-V, and inorganic and organic thin film photovoltaics.
 
Area 4 focuses on emerging technologies such as perovskites and novel device concepts including quantum dots, hot carriers, up- and down-conversion, etc.

The goal of this sub-area is to address and discuss aspects required to ensure the long-term success of the PV industry. Toward 100% renewable electricity and carbon-neutral society, this sub-area focuses on strategies to sustain or accelerate high PV growth rates and rapid cost reductions through government, policy, and financing models that are critical to the success of PV deployment. A circular economy for PV modules, components, and systems is becoming increasingly important as deployments continue to grow and may have significant benefits for a more resilient and diverse supply chain at all stages. This sub-area also discusses the environmental sustainability of PV throughout the life cycle including material supply, manufacturing, usage and end-of-life, and social sustainability such as job creation, education and diversity as well as energy access for underserved communities, fostering widespread acceptance of PV power, or upholding indigenous peoples’ rights with regards to PV project development. Furthermore, to overcome current obstacles and achieve further deployment of PV power generation, various international collaborative efforts have been created, and it is expected to produce valuable outputs and outcomes enabling to accelerate PV deployment in global.

The goal of this sub-area is to address the challenges of massive Renewable Energy (RE) integration into the electric power system by discussing a wide range of technologies and methodologies of energy utilization. Measures to solve fluctuation of the Variable RE (VRE) is a topic to increase its massive integration into the electric power system. Energy Storage Systems (ESS) including batteries are one of the solutions. Surplus energy can be charged and shortage can be filled by its discharge. This control can be done by Demand Response (DR) too. The demand side increases or decreases its energy consumption by using the DR signal sent by the transmission and distribution organization. Virtual Power Plant (VPP) is consisting not only demand side but also small-scale power plant such as photovoltaic systems. They are aggregated and controlled to keep supply-demand balance. Forecasting technologies are an important issue, and they can increase the performance of the above controls. Recent high-speed parallel computation increases Machine learning technologies which can be applied to the forecasting and above controls. This sub-area also welcomes Power Conditioning System (PCS), power electronics and Maximum Power Point Tracking (MPPT) control, which are expected to be harmonized with the electric power system in the massive integrated situation.

Yearly data shows an increase in global temperatures, testing conditions of quality, and safety for PV cell/module depending on regional climate and location properties that should be considered. For a low carbon society, we need to reduce the cost of PV modules, not forgetting price competition with other renewable energy sources. We also need the reliability of component materials such as glass, back-sheet, encapsulant, junction box, and cable within PV module.
On the other hand, from the point of view of realizing a sustainable world, PV module recycle/reuse technology and waste treatment is one of our issues once finishing its role. Developing accurate characterization procedures for novel PV cells/modules such as perovskite solar devices will be essential to boost the entire PV market. Thus, we welcome the cross-sectional discussion by researchers in various fields.
