Perovskite bandgap tuning without quality loss makes perovskites unique among solar absorbers, offering promising avenues for tandem solar cells1,2. However, minimizing the voltage loss when their bandgap is increased to above 1.90 eV for triple-junction tandem use is challenging3,4,5. Here we...
Quantifying recombination in halide perovskites is a crucial prerequisite to control and improve the performance of perovskite-based solar cells. While both steady-state and transient photoluminescence are frequently used to assess recombination in perovskite absorbers, quantitative analyses within a consistent...

perovskite materials can be combined in half tandem within the structure of perovskite solar cells. It is important to note that due to the toxicity of Pb, research has been conducted to replace it with tin (Sn). Experimental studies have measured the MASnI3band gap to be approximately 1.3 ...
Light management techniques used to increase the performance of triple junction tandem solar cells.DDT and ARC are used to maximise solar cell light absorption and efficiency.For ARC, the reflective index (n) values are also varied to analyse their impact on the PV performance of the solar cells...

Perovskite/silicon tandem solar cells (TSCs) have aroused much attentions in recent years. One of keys for achieving highly efficient and stable TSCs is to guarantee effective charge transfer, especially on the rough textured silicon substrate due to the poor adhesion between interlay...
