Perovskite solar cells have aroused a worldwide research upsurge in recent years due to their soaring photovoltaic performance,ease of solution processing,and low cost.The power conversion efficiency record is constantly being broken and has recently reached 26.1%in the lab,which is comparable to the established photovoltaic technologies such as crystalline silicon,copper indium gallium selenide and cadmium telluride(CdTe)solar cells.Currently,perovskite solar cells are standing at the entrance of industrialization,where huge opportunities and risks coexist.However,towards commercialization,challenges of up-scaling,stability and lead toxicity still remain,the proper handling of which could potentially lead to the widespread adoption of perovskite solar cells as a low-cost and efficient source of renewable energy.This review gives a holistic analysis of the path towards commercialization for perovskite solar cells.A comprehensive overview of the current state-of-the-art level for perovskite solar cells and modules will be introduced first,with respect to the module efficiency,stability and current status of industrialization.We will then discuss the challenges that get in the way of commercialization and the corresponding strategies to address them,involving the upscaling,the stability and the lead toxicity issue.Insights into the future direction of commercialization of perovskite photovoltaics was also provided,including the flexible perovskite cells and modules and perovskite indoor photovoltaics.Finally,the future perspectives towards commercialization are put forward.

Perovskite solar cells(PSCs)have attracted tremendous attention as a promising alternative candidate for clean energy generation.Many attempts have been made with various deposition techniques to scale-up manufacturing.Slot-die coating is a robust and facile deposition technique that can be applied in large-area roll-to-roll(R2R)fabrication of thin film solar cells with the advantages of high material utilization,low cost and high throughput.Herein,we demonstrate the encouraging result of PSCs prepared by slot-die coating under ambient environment using a twostep sequential process whereby PbI_(2):CsI is slot-die coated first followed by a subsequent slot-die coating of organic cations containing solution.A porous PbI_(2):CsI film can promote the rapid and complete transformation into perovskite film.The crystallinity and morphology of perovskite films are significantly improved by optimizing nitrogen blowing and controlling substrate temperature.A power conversion efficiency(PCE)of 18.13%is achieved,which is promising for PSCs fabricated by two-step fully slot-die-coated devices.Furthermore,PSCs with a 1 cm2 area yield a champion PCE of 15.10%.Moreover,a PCE of 13.00%is obtained on a flexible substrate by the roll-to-roll(R2R)coating,which is one of the highest reported cells with all layers except for metal electrode fabricated by R2R process under ambient condition.

With the rapid rise in perovskite solar cells(PSCs)performance,it is imperative to develop scalable fabrication techniques to accelerate potential commercialization.However,the power conversion efficiencies(PCEs)of PSCs fabricated via scalable two-step sequential deposition lag far behind the state-of-the-art spin-coated ones.Herein,the additive methylammonium chloride(MACl)is introduced to modulate the crystallization and orientation of a two-step sequential doctorbladed perovskite film in ambient conditions.MACl can significantly improve perovskite film quality and increase grain size and crystallinity,thus decreasing trap density and suppressing nonradiative recombination.Meanwhile,MACl also promotes the preferred face-up orientation of the(100)plane of perovskite film,which is more conducive to the transport and collection of carriers,thereby significantly improving the fill factor.As a result,a champion PCE of 23.14%and excellent longterm stability are achieved for PSCs based on the structure of ITO/SnO_(2)/FA_(1-x)MA_xPb(I_(1-y)Br_y)_3/Spiro-OMeTAD/Ag.The superior PCEs of 21.20%and 17.54%are achieved for 1.03 cm~2 PSC and 10.93 cm~2 mini-module,respectively.These results represent substantial progress in large-scale two-step sequential deposition of high-performance PSCs for practical applications.

为研究桥梁双曲面球型减隔震支座的震后自复位性能并评价现有表征方法,采用公式推导、试验和有限元计算方法,综合对比分析支座的静态残余位移和震后残余位移。基于支座结构推导静态残余位移理论公式,并以竖向设计承载力5000 kN支座为例,进行支座自复位性能的拟静力试验验证;进行双曲面球型减隔震支座模拟地震振动台试验,分析静态残余位移和震后残余位移的差别;以32 m跨典型铁路混凝土简支箱梁为背景,建立MIDAS Civil有限元模型,通过非线性时程分析方法,分析单次和连续2次地震波输入工况下支座的震后残余位移和自复位能力。结果表明:支座静态残余位移为支座等效曲率半径与支座等效摩擦系数的乘积,支座自复位性能的静态残余位移与理论值较为符合,二者偏差为4.92%;振动台试验和非线性时程分析下的支座震后残余位移平均值均为2 mm左右,均低于静态残余位移的5%;双曲面球型减隔震支座支承下的桥梁减隔震体系可以避免产生累积性的震后残余位移,具有强复位能力,而目前用静态残余位移来评价双曲面球型减隔震支座的震后自复位性能较为不妥。

Layer-by-layer (LbL) strategy has been developed to form bulk heterojunction (BHJ) structure for processing efficient organic solar cells (OSCs). Herein, LbL slot-die coating with twin boiling point solvents (TBPS) strategy was developed to fabricate highly efficient OSCs, which matches with large-scale, high throughput roll-to-roll (R2R) industrialized mass process. The TBPS strategy could produce high-quality thin film without any additive, leading to the optimized vertical phase separation with interpenetrating nanostructures, as well as the enhanced charge transport and extraction. Thus, the power conversion efficiency up to 14.42% was achieved for [(2,6-(4,8-bis(5-(2-ethylhexyl-3-fluoro)thiophen-2-yl)-benzo [1,2-b:4,5-b′]dithiophene))-alt-(5,5-(1′,3′-di-2-thienyl-5′,7′-bis(2-ethylhexyl)benzo[1′,2′-c:4′,5′-c′]dithiophene-4,8-dione)]:2,2′-((2Z,2′Z)-((12,13-bis(2-ethylhexyl)-3,9-diundecyl-12,13-dihydro-[1,2,5]thiadiazolo[3,4-e]thieno[2″,3″:4″,5″]thieno[2′,3′:4,5]pyrrolo[3,2-g]thieno[2′,3′:4,5]thieno[3,2-b]indole-2,10-diyl)bis(methanylylidene)) bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile (PM6:Y6) OSCs fabricated via sequentially LbL slot-die coating using the TBPS strategy under ambient condition. The research provides a potential route for industrialized production of high-efficiency and large-area OSC devices.

Organic solar cells(OSCs)have been developed rapidly in past years,due to the fast evolution of wide-bandgap copoly-mer donors and low-bandgap non-fullerene acceptors[1−9].At present,the highest power conversion efficiencies(PCEs)for single-junction OSCs and tandem OSCs exceed 19%and 20%,respectively[10,11].These OSCs are typically fabricated by us-ing low-boiling-point solvent chloroform(CF)with an effect-ive arealing-point solvent for upscaling lab cells to industrial-scale mod-ules[12],exhibiting simple operation,low cost,and high materi-al utilization[13−15].Herein,a typical OSC material system PM6:Y6(Fig.1(a))was used to fabricate OSCs modules via doc-tor-blading deposition in ambient condition,and the influ-ence of the ambient temperature and substrate temperature on the film quality was investigated.

Perovskite solar cells(PSCs) constitute a competitive and promising photovoltaic technology owing to their advantages of high absorption coefficient,long carrier lifetime and low-cost manufacturing.The perovskite morphology plays a critical role in achieving high efficiency and stable devices.In order to improve quality of perovskite film,we adopted the configuration of ITO/SnO/Perovskite/Spiro-OMeTAD/Ag(shown in Figure 1a) to fabricate PSCs by varying processing conditions and additives.An encouraging power conversion efficiency(PCE) of 13.00% is achieved for roll-to-roll(R2R) coated triple cation flexible devices in ambient condition.Furthermore,an additives synergy strategy of methylammonium acetate(MAAc) and molecular phenylurea is proposed to one-step,antisolvent-free doctor-blade methylammonium lead iodide(CHNHPbI,MAPbI) PSCs in ambient with a wide range of humidity from 45% to 82%,and the PSCs exhibited comparable performance parameters.An impressive PCE of 20.34% has been achieved under the humidity as high as over 80%(in Figure 1b).

Flexible perovskite solar cells(f-PSCs) have attracted tremendous attention as a promising alternative candidate for clean energy generation due to their advantages of light weight and flexibility [1]. Slot-die coating is a robust and facile deposition technique that can be applied in large-area roll-to-roll(R2 R) fabrication of thin film solar cells with the advantages of high material utilization, low cost and high throughput [2]. Herein, we demonstrate the encouraging result of f-PSCs prepared by slot-die coating under ambient environment using a two-step sequential process whereby PbI:CsI is slot-die coated first followed by a subsequent slot-die coating of organic cations containing solution. A PCE of 13.00% was obtained on a flexible substrate by the R2 R coating, which is one of the highest reported cells with all layers except for metal electrode fabricated by R2 R process under ambient condition [3].
