A Roadmap For Tandem Photovoltaics

What is the International Technology Roadmap for Photovoltaics (ITRPV)?

The aim of the International Technology Roadmap for Photovoltaics (ITRPV) is to inform suppliers and cus-tomers about anticipated technology trends in the crystalline silicon (c-Si) based PV industry and to stimulate discussions on required improvements and standards.

What is a photovoltaic technology roadmap?

1. Executive Summary The photovoltaic (PV) industry needs to provide power generation products that can compete with both, conventional energy sources and other renewable sources of energy. An international technolo-gy roadmap can help to identify trends and to define requirements for necessary improvements.

What is a PV energy roadmap?

The roadmap has been designed with milestones that the international community can use to ensure that PV energy development efforts are on track to achieve the GHG emissions reductions that are required by 2050.

What is the Roadmap for silicon solar cell development?

Generally speaking, the roadmap for silicon solar cell development calls for the introduction of passivating contacts to the mainstream high-volume production of PV devices, then a possible switch to n-type material and finally the introduction of tandem cells. Below we describe challenges for the different technology classes.

What is the purpose of a PV roadmap?

The objective of the roadmap is not to recommend detailed technical solutions for identified areas in need of improvement, but in-stead to emphasize to the PV community the need for improvement and to encourage the develop-ment of comprehensive solutions.

What is a terawatt-scale PV conversion roadmap?

This roadmap outlines the critical areas of development in all of the major PV conversion technologies, advances needed to enable terawatt-scale PV installation, and cross-cutting topics on reliability, characterization, and applications.
