Power conversion efficiency(PCE) of perovskite solar cells(PSC) has been skyrocketed to certified 25.5% owing to their improved and tunable optoelectronic properties. Although, various strategies have been adopted to date regarding PCE and stability enhancement within PSC technology, certain instability factors(moisture, heat, light) are hindering their commercial placement. Recently, all-inorganic PSCs got hype in the photovoltaic research community after they attained PCE > 20% and due to their significant endurance against heat and light mishmashes, but there only left moisture sensitivity as the only roadblock for their industrial integration. Here, we review the recent progress of additive inclusion into allinorganic(CsPbX_(3)) PSCs to stabilize their intrinsic structure and to withstand the performance limiting factors. We start with the detailed description of chemical instability of different perovskite compositions, phase segregation, and how organic molecules and dyes help to repair the structural defects to improve the overall PCE and stability of PSCs. Moisture endurance as a result of chemical passivation through organic additives, low-dimensional inorganic PSCs to enhance device stability and scalable fabrication of CsPbX_(3) PSCs are also reviewed. The challenges of module degradation and design implications with proposed strategies and outlook are interpreted in the ending phrases of this review.

CaO based sorbents have great potential for commercial use to capture CO_(2) of power *** the demand of producing sorbents with better cyclic performance,CaO-based sorbents derived from different kinds of calcium precursors,containing calcium carbonate(CC-CaO),calcium gluconate monohydrate(CG-CaO),calcium citrate(CCi-CaO)and calcium acetate monohydrate(CA-CaO),were tested cyclically and compared using simultaneous thermal analyzer(STA).And further study was conducted on the sorbents modified with citric acid monohydrate and 50%gluconic acid solution by wet mixing combustion *** modified sorbents showed better performance and higher pore parameters as well as porous microstructure with more organic acid *** 20 cycles of carbonation and calcination,the C2CCi8(CaO:citric acid=2:8 by mass ratio)and C2G8(CaO:gluconic acid=2:8 by mass ratio)sorbent possess CO_(2) capture capacity of 0.45g·g^(-1)(g CO_(2) per g sorbents)and 0.52 g·g^(-1) *** citric acid was more effective for modification than gluconic acid for extended 50 ***,good linear relationship between CaO conversion and specific surface area as well as pore volume were determined,of which the specific surface area showed closer correlation with CaO conversion。
