Es wird ein Überblick über den Forschungsstand des BMFT-Projektes "Physikalisches Verhalten und energetische Bewertung von Solarzellen mit einem oder mehreren Übergängen unter realistischen Bezugsbedingungen" gegeben. Es werden Verfahren der Kalibrierung von Solarzellen diskutiert. Speziell wird Meßtechnik für Konzentrator- und Mehrfachzellen vorge...
III-V multi-junction solar cells have become standard in space and in terrestrial concentrator systems. These devices reach the highest efficiencies of any photovoltaic technology so far. This is enabled by stacking solar cells of several III-V compound semiconductors, which absorb different parts of the solar spectrum. The current landmark for III...
The rapid rise of perovskite solar cells (PSCs) is increasingly limited by the available charge-selective contacts. This work introduces two new hole-selective contacts for p–i–n PSCs that outperform all typical p-contacts in versatility, scalability and PSC power-conversion efficiency (PCE). The molecules are based on carbazole bodies with phospho...
Hybrid metal-halide perovskite solar cells have experienced a tremendous development within a short time period. In 2009 the first perovskite single-junction solar cell with a power conversion efficiency (PCE) of 3.8% was presented. Just eleven years later, in year 2020, a PCE of 25.5% was achieved, which approaches the value of silicon single-junc...
