Hysteresis-Free and Efficient Perovskite Solar Cells Using SnO2 with Self-assembly L-Cysteine Layer

Isolating the Oxygen Adsorption Defects on Sputtered Tin Oxide for Efficient Perovskite Solar Cells

“…Due to the impressive photovoltaic properties of perovskite materials, − the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has gradually approached crystalline silicon solar cells in just over a decade. − It is a consensus in both academia and industry that PSCs have the biggest potential to become the next generation photovoltaic cells. − Realizing the industrial production of PSCs is the further developmental goal in the field. One of the important issues is how to achieve low-cost large-scale preparation of the electron transport layer (ETL). , Common ETL materials include TiO 2 , , SnO 2 , − C 60 , , and so on. Among them, SnO 2 is the most commonly used ETL material in n-i-p devices.…”

Enhancing the perovskite solar cell performance by the interface modification of Zn–Sn–O compound heterostructures

“…9 PSC technology is an effective way to develop a flexible energy source for wearable devices. 10 Additionally, from the material point of view, perovskite materials exhibit unique properties like high absorption coefficients across the visible spectrum. 9 The bandgap of the perovskite layer can be tuned by changing the material composition.…”

Hole-transporting interlayers based on pyrazine-containing conjugated polymers for perovskite solar cells

“…[4][5][6] One efficient strategy to improve the stability and power conversion efficiency of PSCs is introduction of organic or inorganic charge-transport materials between the perovskite absorber and electrode. [7][8][9][10][11][12][13][14][15] Organic semiconductor materials such as conjugated small molecules or polymers attract considerable attention for application in PSCs due to their unique electronic properties, good conductivity and mechanical flexibility. [16][17][18] These materials can hinder additionally the penetration of moisture to the photoactive layer due to their hydrophobic nature.…”
