Perovskite solar cells combine high carrier mobilities with long carrier lifetimes and high radiative efficiencies. Despite this, full devices suffer from significant nonradiative recombination losses, limiting their VOC to values well below the Shockley–Queisser limit. Here, recent advances in ...
owing to the presence of non-radiative recombination losses. In this Review, we analyse the predominant pathways that contribute to non-radiative recombination losses in perovskite solar cells and evaluate their impact on device performance. We then discuss how non-radiative recombination losses can be...

Compared with inorganic or perovskite solar cells, the relatively large non-radiative recombination voltage losses (Delta Vnon-rad) in organic solar cells (OSCs) limit the improvement of the open-circuit voltage (V-oc). Herein, OSCs are fabricated by adopting two pairs of D-pi-A polymers (PB...
Perovskite quantum dotsNon-radiative recombinationTRPLColloidal perovskite (cesium lead bromide-iodide) quantum dots (PQDs) with different iodine concentration were prepared. These PQDs show excellent optical properties with high light absorption and high photoluminescence. Light absorption is in the range ...
Reducing interface nonradiative recombination is important for realizing highly efficient perovskite solar cells. In this work, we develop a synergistic bimolecular interlayer (SBI) strategy via 4-methoxyphenylphosphonic acid (MPA) and 2-phenylethylammonium iodide (PEAI) to functionalize the perovskite ...
Surface reflections and non-radiative recombinations create energy losses in perovskite solar cells (PSCs) by hindering the generation and extraction of carriers. These losses can reduce device efficiency in practical applications as the incident angle of sunlight varies throughout the day. Here we ...
