Abstract

In the last decade the field of PV has become extremely dynamic in terms of implementation of innovations within solar cell development and module production. Al-BSF devices are beginning to fade out as more-advanced and higher-efficiency solar cells and modules enter the PV market. It is believed that c-Si-based tandem solar cells will also be commercially available within three to five years (possibly sooner), as also confirmed in the ITRPV roadmap. This paper provides a concise overview of existing c-Si-based 2-, 3- and 4-terminal tandem technologies, summarizes the current development status, and sets out the future roadmap. In addition, a discussion is included of what will be required over the coming years to bring these promising technologies to market, enabling commercial efficiencies above 30%.
