Lay Summary (German)

Lead
Solarzellen aus Silizium dominieren den Photovoltaik-Markt seit Jahrzehnten. In den letzten Jahren sanken die Kosten von Siliziumzellen stark, sodass diese inzwischen weniger als ein Drittel der Kosten eines Photovoltaiksystems mit Unterkonstruktion, Netzanschluss und Steuerelektronik ausmachen. Die vielversprechendste Strategie, den Preis von Solarstrom weiter zu senken, ist deshalb die Effizienz der Solarzellen zu erhöhen und so die Systemkosten per erreichter Leistung zu reduzieren. Da die Effizienz von Siliziumzellen schon nahe am theoretischen Maximum liegt, und bisher keine Solarzellentechnologie bei vergleichbaren Kosten höhere Effizienzen erreicht hat, müssen alternative Lösungen gefunden werden.
Lay summary

Inhalt und Ziel des Forschungsprojektes

Ziel dieses Forschungsprojektes ist es, Solarzellen zu entwickeln, die deutlich höhere Effizienzen als Siliziumzellen aufweisen, aber nur geringfügig teurer sind. Dies soll erreicht werden, indem Siliziumzellen oder Chalcogenid-Solarzellen – welche ähnlich hohe Effizienzen aufweisen – mit verschiedenen anderen Solarzellentechnologien kombiniert werden. In solchen Mehrfachsolarzellen absorbiert jede Zelle einen anderen Teil des Sonnenspektrums, wodurch höhere Effizienzen als nur mit einem Material erreicht werden können. Insbesondere werden Silizium- und Chalcogenid-Solarzellen mit Perovskit-Solarzellen kombiniert, welche in den letzten Jahren enorme Effizienzsteigerungen erfahren haben und kostengünstig hergestellt werden können.

Wissenschaftlicher und gesellschaftlicher Kontext

Gemäss der Energiestrategie 2050 der Schweizer Regierung soll Solarstrom in Zukunft einen wesentlichen Bestandteil des Schweizer Strom-Mixes ausmachen. Zu diesem Ziel trägt dieses Projekt bei, indem es die Kosten von Photovoltaikanlagen durch erhöhte Effizienz weiter senkt, und so mithilft, den Weg in eine nachhaltige Zukunft zu ebnen. Zusätzlich wird die noch junge Perovskit-Technologie weiter gefördert, während neue Perspektiven für etablierte Solarzellentechnologien eröffnet werden.

Abstract

This project aims at developing photovoltaic (PV) technologies as building blocks for tandem solar cells with efficiencies beyond those achievable with state-of-the-art industrial single-junction cells. Since decades, the PV market is dominated by wafer-based crystalline silicon (c-Si) solar cells with lab record efficiencies of 25%, and production efficiencies of 17-22%. As these values are already close to the theoretical limit of single-junction c-Si cells, further improvements will not be possible by mere incremental technological innovation. The most promising approach to overcome this limit is to combine two single-junction cells with different optical band-gaps to form tandem solar cell systems. Highly efficient tandem cell systems involving the high-efficiency yet industrially viable c-Si or copper indium gallium diselenide (CIGS) cell technologies have so far not been successfully realized, mainly due to the difficulty to find a suitable wide-ban-dgap cell that delivers the necessary photocurrent while exhibiting excellent electrical properties.Recently, the situation drastically changed with the emergence of highly efficient wide-band-gap thin-film solar cells that deliver high photocurrents, based either on perovskite or chalcogenide absorbers. In addition, low-band-gap cells based on CIGS compounds have recently reached efficiencies beyond 20%, almost as efficient as the best c-Si cells. In parallel, heterojunction c-Si solar cells with record infrared performance were demonstrated. These recent developments from Swiss labs very likely enable industrially relevant tandem systems with efficiencies beyond 30%. The project consortium has a vast experience and top-notch infrastructures required to fabricate state-of-the-art devices for all these high-efficiency PV technologies. Each of these will be adapted and optimized to be integrated into tandem cells. Specifically, the Photovoltaics and Thin Film Electronics Lab (PV-Lab) at EPFL will develop dedicated amorphous Si (a-Si)/c-Si heterojunction bottom cells, the Thin Films and Photovoltaics group (TFPV) at Empa will focus on chalcogenide cells with tunable band-gaps, including CIGS, CdTe and kesterite absorbers, and the Laboratory of Photonics and Interfaces (LPI) at EPFL will improve perovskite solar cells. These PV building blocks will then be combined and integrated into tandem devices, either in monolithic or mechanically stacked 4-terminal configuration, with the potential to reach efficiencies beyond 30%. Simultaneously, the device physics and material properties will be analysed and optimized in close collaboration with PV2050 project ‘Simulation and Characterization: from Cells to Systems’ to assess the potential of each of these emerging technologies individually and when combined into tandem cells. This project will also take inputs from the PV2050 projects ‘Novel Materials and Interfaces for Advanced Photovoltaic Devices’ and ‘Novel Generation Perovskites Devices’, and will provide input to the two PV2050 projects related to building-integrated applications of emerging solar technologies, ‘Photovoltaics into the Built Environment’ and ‘Sustainability, Market Deployment and Interaction with the Grid - the impacts of advanced photovoltaic solutions’.
