“…Development of highly efficient lead-free PSCs is also an alternative choice to extend their application range in the PV markets, especially for the indoor power generation like wearable power sources that have a strict limit on lead content [86][87][88]. It was demonstrated that tin PSCs could be the next generation of PSCs for realizing over 20% efficiency and the strategies for their mass production have been investigated [20]. Moreover, developing reducing solvent system for Sn 2+ precursor, constructing antioxidant capping layer during the crystallization of tin perovskite film, and the investigation of compatible device encapsulation approaches also led to a large stability improvement of tin PSCs [89,90].…”

“…With the continuous progress of PSCs toward commercialization, exploiting eco-friendly lead-free perovskite materials has also become a hot research topic in this field in view of the toxicity of Pb element in Pb-containing PSCs giving rise to the concern of environmental pollution [20][21][22][23]. So far, the highest certified efficiency of lead-free PSCs has reached 11.22%, enabled by minimizing the defect density in tin halide perovskite films via a template-growth deposition method [24].…”

“…Furthermore, the ionic defects at bulk and grain boundaries also decrease the carrier diffusion length and reduce the light‐absorption rate of the perovskite absorber, resulting in the loss of J SC [59] . Besides, the non‐radiative recombination also reduces the shunt resistance and thus impacts the FF of solar cells according to the equivalent circuit model [60] . Thus it is critical to reduce the deep trap density via defect passivation in PSCs.…”

Perovskite solar cells (PSCs) are a promising third‐generation photovoltaic (PV) technology developed rapidly in recent years. Further improvement of their power conversion efficiency is focusing on reducing the non‐radiative charge recombination induced by the defects in metal halide perovskites. So far, defect passivation by the organic small molecule has been considered as a promising approach for boosting the PSC performance owing to their large structure flexibility adapting to passivating variable kinds of defect states and perovskite compositions. Here, the recent progress of defect passivation toward efficient and stable PSCs was reviewed from the viewpoint of molecular structure design and device performance. To comprehensively reveal the structure‐performance correlation of passivation molecules, it was separately discussed how the functional groups, organic frameworks, and side chains affect the corresponding PV parameters of PSCs. Finally, a guideline was provided for researchers to select more suitable passivation agents, and a perspective was given on future trends in development of passivation strategies.

“…Among all these emerging PV technologies, PSCs are the most viable alternate offering a comparable PCE to the mature silicon solar cells. In addition, their lower cost, adjustable bandgap, low-temperature solution processability, lower exciton binding energy, high light absorption coefficients, long charge carrier diffusion lengths, multiple options of performance enhancement and significantly simpler mass production techniques bring in added advantages that conventional Si based technologies lack [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Furthermore, unlike conventional Si solar cells, PSCs also have high performance in diffused or dim lights, making them ideal for indoor applications [ 11 ].…”

View full text Add to dashboard Cite

Application of MXene materials in perovskite solar cells (PSCs) has attracted considerable attention owing to their supreme electrical conductivity, excellent carrier mobility, adjustable surface functional groups, excellent transparency and superior mechanical properties. This article reviews the progress made so far in using Ti3C2TxMXene materials in the building blocks of perovskite solar cells such as electrodes, hole transport layer (HTL), electron transport layer (ETL) and perovskite photoactive layer. Moreover, we provide an outlook on the exciting opportunities this recently developed field offers, and the challenges faced in effectively incorporating MXene materials in the building blocks of PSCs for better operational stability and enhanced performance.
