This topic description for the EU PVSEC 2021 implements some changes in the topic description from 2020 which reflect the widening scope of the conference. In order to help and assist you in deciding to submit a contribution for this conference, we provide you with some explanations and clarifications, in particular in the new or re-arranged topics. We appreciate that some level of overlap between different subtopics is unavoidable - if you have doubts about the appropriate subtopic to choose, please consider the one most appropriate to the main novelty of your work.

TOPIC 1: New Materials and Concepts for Photovoltaic Devices

This is traditionally the topic where the ongoing front-end research is presented. It is the right place for contributions to the understanding of photovoltaic conversion, including in new or exotic materials and cross-fertilisation with other fields of optoelectronics.


1.1 Fundamental Studies

Theoretical studies of materials, cells and modules; new measurement techniques, modelling and simulation.

This subtopic comprises all theoretical work on photovoltaic conversion as well as for instance measurement techniques to reveal e.g. atomic structures or electronic properties.

1.2 New Materials and Concepts for Cells and Modules

New cell materials and concepts, e.g. use of nanotechnologies and quantum effects. New module materials and concepts.

Here we usually place papers which typically describe experimental research realising new materials and device concepts, often on a rather fundamental or prototype (i.e. low TRL) level.


TOPIC 2: Silicon Materials and Cells

Topic 2 collects all presentations which deal with crystalline silicon up to cell level. Amorphous and microcrystalline silicon is also covered in subtopic 2.4. The whole spectrum of Si technology is divided into 6 subtopics, which address typical issues and fields of technology development, many of them dealt with on a corporate R&D level.
An exception is tandem structures combining other materials with silicon which are grouped together in subtopic 3.5.
Contributions which focus on Si module encapsulation and reliability, or electrical performance measurement technologies are better placed in subtopic 4.1.


2.1 Feedstock, Crystallisation, Wafering, Defect Engineering

Novel and advanced production technologies for silicon, ingots and wafers, solar-grade silicon properties and specifications, testing, performance, costs. Influence of crystallisation parameters, impact of residual defects and impurities, and their mitigation.

This subtopic focuses on all the steps required for the production of high quality silicon up to wafer stage ready for subsequent cell fabrication.

2.2 High Temperature Route for Si Cells

Solar cell architectures based on high temperature poly-Si based and classical high temperature approaches (PERX, IBC, etc.).

Subtopics 2.2 and 2.3 are where research work on crystalline Si cells is presented, divided into two main themes, which employ either high temperature or low temperature processing routes. This subtopic replaces a previous closely related one, which was titled 'Homojunction Solar Cells'. It includes technology development for these approaches.

2.3 Low Temperature Route for Si Cells

Solar cell architectures based on classical a-Si passivation schemes (e.g. HIT), as well as approaches relying on other low temperature passivation based systems.

Subtopics 2.2 and 2.3 are where research work on crystalline Si cells is presented, divided into two main themes, which employ either high temperature or low temperature processing routes. This subtopic replaces a previous closely related one, which was titled 'Heterojunction Solar Cells'. It includes technology development for these approaches.

2.4 Thin Film and Foil-Based Si Cells

Amorphous and microcrystalline silicon, thin crystalline silicon, silicon foils (<20µm): theoretical studies, innovation in processing and manufacturing technologies, manufacturing up-scaling.

Improvements in manufacturing solutions for mass production are crucial in order to continue the drive towards lower costs, while maintaining high quality standards. New developments in manufacturing technologies should be submitted to this subtopic.


TOPIC 3: Perovskites and Other Non-Silicon Materials and Devices, Multijunctions/Tandems

This Topic is subdivided amongst the different photovoltaic materials in use today or in the demonstration phase that are not based on silicon. An exception is tandem structures combining other materials with silicon which are grouped together in subtopic 3.5.
The Topic comprises theoretical studies, innovations in processing and manufacturing technologies and upscaling, measurement and characterisation.
If the paper describes the encapsulation on a module level, it probably is better to be presented under subtopic 4.1. For materials which don’t fall under any of those listed here you should consider Topic 1.

This subtopic covers recent developments in power electronics, measurement, modelling and control focusing on the interface between a PV plant and the electrical grid. The subtopic addresses relevant developments, including from digitalisation, for a reliable, secure and optimized grid operation at high PV penetration. This also covers concepts such as advanced inverter functionality, voltage and frequency regulation, power quality and stability, islanded operation, or micro-grids. ICT integration including (cyber) security is also included.

In this subtopic the wide spectrum of storage systems is addressed. We consider papers which describe the technical relation and interaction between PV generation and storage/conversion, aimed to optimise the “dispatchability” and functionality of PV driven electricity systems, covering the full range of size from grid to stand-alone systems. The time scale covers the full range from grid stabilisation to seasonal storage.

6.5 Energy System Integration

Applications in which PV electricity is converted directly into a useful product or service, including conversion of PV electricity into other energy carriers (e.g. P2X, hydrogen, desalination).

This subtopic comprises the systemic approach to integrate PV generated electricity, in ever increasing amounts, into the wider energy system, including balancing supply and demand. This would also include hybrid systems with auxiliary generators, such as biomass CHP. Experience from other renewable and grid operators are welcome in this topic. PV solutions to meet the needs of increased electromobility are highly relevant.
Industrial applications in which PV generated electricity is converted directly into a useful product or service, including conversion of PV electricity into other energy carriers, e.g. PV-to-gas/fuels including hydrogen production (P2X); Water desalination, sterilization and upgrading; PV process heat and other novel applications in industrial processes.


TOPIC 7: Finance, Markets and Policies

This topic is aimed at researchers and other key stakeholders dealing with the financing, market development and policymaking necessary to ensure a rapid deployment of PV on a global scale.

In this subtopic we address market analysts, project developers and business experts from finance, and investment and utilities. It covers the more non-technical aspects of installing and dispatching PV electricity, new scenarios and the market conditions required to make them happen as well as analysis of present market development and trends.

7.2 Policies and Scenarios for Renewables, Societal and Global Challenges

Modelling and scenario analysis; cross-fertilisation with other renewable energy systems; Policies for R&D, innovation and deployment; trade barriers, regulatory frameworks for grid integration; education, training and job creation; PV impacts on society and global challenges like sustainability, global change and poverty alleviation. Upscaling of PV and deployment at TW scale.

This is the subtopic for policymakers, researchers, energy-law experts, media communicators, but also teachers and communicators. The more global aspects solicit papers from large, often collaborative efforts to analyse the role of PV in a larger context, often related to energy modelling or scenario analysis. This includes socio-economic research and societal aspects. Projecting PV towards 2030, 2050 and comparing the calculations are typical subjects in this subtopic, as well as the relation of PV to greater policy efforts in the worlds regions, or international agreements, including UN Sustainable Development Goals and IPPC.
