Multi-junction (tandem) solar cells (TSCs) consisting of multiple light absorbers with
considerably different band gaps show great potential in breaking the Shockley–Queisser (S …

Tandem solar cells are the next step in the photovoltaic (PV) evolution due to their higher
power conversion efficiency (PCE) potential than currently dominating, but inherently limited …

Do** of perovskite semiconductors and passivation of their grain boundaries remain
challenging but essential for advancing high-efficiency perovskite solar cells. Particularly, it …

Monolithic all-perovskite tandem solar cells offer an avenue to increase power conversion
efficiency beyond the limits of single-junction cells. It is an important priority to unite …

Challenges in fabricating all-perovskite tandem solar cells as modules rather than as single-
junction configurations include growing high-quality wide-bandgap perovskites and …

Carrier extraction in mixed tin–lead perovskite solar cells is improved by modifying the top
and bottom perovskite surfaces with ethylenediammonium diiodide and glycine …

Longevity has been a long-standing concern for hybrid perovskite photovoltaics. We
demonstrate high-resilience positive-intrinsic-negative perovskite solar cells by …

Formamidinium–caesium mixed-cation perovskites have shown better thermal stability than
their methylammonium-containing counterparts but they suffer from photoinstability induced …

High‐performance tin‐lead perovskite solar cells (PSCs) are needed for all‐perovskite‐
tandem solar cells. However, iodide related fast photodegradation severely limits the …

In recent years, the perovskite solar cells have gained much attention because of their ever-
increasing power conversion efficiency (PCE), simple solution fabrication process, flyable …
