“…Interestingly, a lead-free solar cell, based on a CsSnI 3 light absorber (as a CH 3 NH 3 PbI 3 replacement) was also reported, although PCE was very poor and only improved upon the addition of SnF 2 to the active layer (best for 20% addition), but on the other hand this showed good stability for more than 250 h, especially those replacing the spiro-OMeTAD by m-MTDATA as HTL [36], while in CH 3 NH 3 PbI 3 cells, this substitution lead to more than 1000 h stable cells [37]. More recently, the replacement of spiro-OMeTAD by a Zn-derivative porphirin in a lead-free solar cell has led to extended stability up to 60 h for water stability and 100 h for thermal stability, an increment of 75% when compared to control cells [38].…”

Photovoltaic technology is progressing very fast, both in a new installed capacity, now reaching a total of more than 400 GW worldwide, and in a big research effort to develop more efficient and sustainable technologies. Organic and hybrid solar cells have been pointed out as a technological breakthrough due to their potential for low economical cost and low environmental impact; but despite impressive laboratory progress, the market is still beyond reach for these technologies, especially for perovskitebased technology. In this review, the historical evolution and relationship of efficiency and stability is addressed, including Life Cycle Assessment studies which provide a quantitative evaluation of environmental impacts in several categories, such as human health or freshwater ecotoxicity, with special focus on lead toxicity. The main conclusion is that there is no unsurmountable barrier for the massive deployment of photovoltaic systems with perovskite solar modules, if the stability is extended to lifetimes similar to technologies already in the market. The results of this review provide some recommendations mainly focused on the best options for improved stability (avoiding mainly moisture and oxygen degradation) by using metal oxides, ternary or quaternary cations, or the novel 2D/3D approach, and the encapsulation effort which should also take into account the recyclability of the materials and the low environmental impact processes for up-scaled industrial production. Research guidelines should take into account the end-of-life of the devices and cleaner routes for production avoiding toxic solvents.

“…Another supporting explanation is that the pyridine core of HTMs acts as a passivating agent for the perovskite layer and perovskite/HTM interface. [57][58][59] 0.6 0.7 0.8 0.9 and 3,5PyDANCBZ is about 28.1 € and 27.0 € per gram, respectively, which is significantly lower than that of Spiro-OMeTAD (~ 400 € per gram, Sigma-Aldrich). Additionally, the optimal concentration of 2,6PyDANCBZ (39.6 mg mL -1 ) was almost half of Spiro-OMeTAD solution (72.3 mg mL -1 ), this will further allow to achieve lower the material cost during device fabrication.…”

Developing cost-effective and rational hole transporting materials is critical for fabricating high-performance perovskite solar cells (PSCs) and to promote their commercial endeavor. We have designed and developed pyridine (core) bridging diphenylamine-substituted carbazole (arm) small molecules, named as 2,6PyDANCBZ and 3,5PyDANCBZ. The linking topology of core and arm on their photophysical, thermal, semiconducting and photovoltaic properties were probed systematically. We found that the 2,6PyDANCBZ shows higher mobility and conductivity along with uniform film-forming ability as compared to 3,5PyDANCBZ. The PSCs fabricated with 2,6PyDANCBZ supersede the performance delivered by Spiro-OMeTAD, and importantly also gave improved long-term stability. Our findings put forward small molecules based on core-arm linking topology for cost-effective hole selective layers designing.

“…Chung et al [54] first demonstrated CsSnI 3 as a solid electrolyte in DSSCs. Afterward Chen et al [58] [59] reported the replacement of spiro-OMeTAD by a Zn-derivative porphyrin in a lead-free solar cell has resulted in stability up to 60 h for water and 100 h for thermal stability.…”

Organic-inorganic perovskite materials, due to the simultaneous possession of various properties like optical, electronic and magnetic beside with their structural tunability and good processability, has concerned the attention of researchers from the field of science and technology since long back. Recently, the emergence of efficient solar cells based on organic-inorganic perovskite absorbers promises to alter the fields of thin film, dye-sensitized and organic solar cells. Solution processed photovoltaics based on organic-inorganic perovskite absorbers CH3NH3PbI3 have attained efficiencies of over 25%. The increase in popularity and considerable enhancement in the efficiency of perovskites since their discovery in 2009 is determined by over 6000 publications in 2018. However, although there are broad development prospects for perovskite solar cells (PSCs), but the use of CH3NH3PbI3 results in lead toxicity and instability which limit their application. Therefore, the development of environmental-friendly, stable and efficient perovskite materials for future photovoltaic applications has long-term practical significance, which can eventually be commercialized.
