Toward Stable Perovskite Solar Cell Architectures: Robustness Against Temperature Variations of Real-World Conditions

ZnO nanostructured materials for emerging solar cell applications

“…Perovskite is a class of compound with the general formula ABX 3 , where A and B are cations with different sizes, and X is an anion. The rst attempt that began the story of the perovskite-sensitized solar cells, or recently denoted as the perovskite-solar cell, (PSC) [74][75][76][77] was made in 2009 by Kojima et al, where two organolead halide perovskite nanocrystals (CH 3 NH 3 PbBr 3 and CH 3 NH 3 PbI 3 ) were found to efficiently sensitize TiO 2 for visible-light conversion in photoelectrochemical cells. 78 They reported that the solar energy conversion efficiency of CH 3 NH 3 PbI 3 , also known as methyl ammonium lead iodide (MAPI), is higher than CH 3 -NH 3 PbBr 3 with a value of 3.8% and 3.1%, respectively.…”

Thermal Stability and Cation Composition of Hybrid Organic–Inorganic Perovskites

“…1−4 Today, the major challenge hindering the commercialization of perovskite-based PV is their instability with respect to various stress factors such as moisture, 5 oxygen, 6 elevated temperatures, 7,8 and temperature variations. 9,10 Regarding moisture and oxygen degradation, various improvements allowing for stable solar cells over 2000 h have been reported recently. 11−13 With respect to the thermal stability of PSCs, efforts were made in the past years.…”

“…Facile processing of perovskite thin films and enormous efforts in the field led to ever-greater advancements in perovskite solar cells (PSCs). As a result, record power conversion efficiencies (PCEs) increased from 3.8% in 2009 to certified values of over 25% in 2021. − Today, the major challenge hindering the commercialization of perovskite-based PV is their instability with respect to various stress factors such as moisture, oxygen, elevated temperatures, , and temperature variations. , Regarding moisture and oxygen degradation, various improvements allowing for stable solar cells over 2000 h have been reported recently. − With respect to the thermal stability of PSCs, efforts were made in the past years.

Energy Yield Advantages of Three-Terminal Perovskite-Silicon Tandem Photovoltaics

“…6 Scalability and stability remain the main problems of perovskite technology, although significant improvements have been reported recently. [7][8][9][10] Two double-junction tandem architectures have been intensively researched and developed so far: two-terminal (2T) [11][12][13][14] and four-terminal (4T) [15][16][17] architectures. In 2T architecture, two solar cells are monolithically integrated and electrically connected in series (see Figure 1A).…”
