Due to its low stability and poor scalability, it still lags in commercial performance concerning the crystalline silicon solar cell. Most of the high-efficiency perovskite solar cells (PSC) reported in the literature are on a 0.01 cm<sup>2</sup> area, and the efficiency of PSC decreases with an increase in area. The maximum said stability to date is 10,000 h which is relatively low compared to crystalline silicon technology. This work discussed the causes of instability, degradation mechanism, scalable fabrication methods, and high-stability perovskite solar cell. It emphasised the need for setting up testing protocols for universal stability testing of perovskite solar cell technology. The study found that trap states in the absorber layer, hole transport layer (HTL), and electron transport layer (ETL) are the reason for lower stability. The lower dimension perovskite solar cell shows better stability compared to its 3D counterparts.</p></div>","PeriodicalId":18283,"journal":{"name":"Materials Science for Energy Technologies","volume":"6 ","pages":"Pages 437-459"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41545583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Composting is an effective way to treat agricultural waste and further produce organic fertilizer, achieving waste minimization and stabilization. This paper reviews the current situation of agricultural waste pollution and composting technology, introduces the parameters that influence of the composting process and the optimal conditions, and presents the indicators for evaluating the decay of compost products and the evaluation criteria as well. In the composting process, small-molecule organic acids produced by the degradation of easily degradable organic matter such as sugars and lipids and various enzymes produced by microorganisms (phytase, phosphatase, etc.) can mineralize organic phosphorus such as phytate and phospholipids, promote phosphorus activation and provide phosphorus sources for microorganisms, so the conversion of organic matter and phosphorus is related to the fertilizer effect of composted products. Therefore, the clarification of the characteristics of organic matter and phosphorus transformation in the composting process is an important prerequisite for the resource utilization of agricultural organic waste.

Likewise, the average grain size elevated from 40.13 nm to 53.27 nm accompanied by the elevation of the number of agglomerated crystallites in a grain per SEM particle (1.98 to 3.55). The average particle size of Mo and Se co-doped BST was found as 26.63 nm. The lowering of pore size as well as pore volume of BST was also observed after doping.

Several methodologies have been developed to assess the energy performance of buildings, including the energy signature, which is an empirical tool used to represent the real energy performance of buildings. Synthetic data of energy consumption of buildings are generated by ECOTECT simulation program, which is a class of energy models that uses characteristic data (dimensional, physical and location) of the building to predict energy consumption. The primary goal of this research is to examine how solar rays and occupants affect a residential building's energy signature in Errachidia, a city in the southeast of Morocco characterized by its arid climate. The results show that when solar radiation was taken into account, the outcomes of the building's intrinsic characteristics (a and b) enhanced the signature. The distinct response in energy use serves as justification. In fact, the solar radiation provides a significant improvement with an important <em>R<sup>2</sup></em> accuracy of about 0.999. Moreover, the introduction of the occupancy factor has a significant impact on energy savings and temperature fluctuations in energy consumption. The importance of parameter <em>b</em> related to the fixed loads of the building is more influenced by the occupancy factor.
