Complex Additive‐Assisted Crystal Growth and Phase Stabilization of α‐FAPbI3 Film for Highly Efficient, Air‐Stable Perovskite Photovoltaics
Autor: Hock Beng Lee, Rishabh Sahani, Vasanthan Devaraj, Neetesh Kumar, Barkha Tyagi, Jin‐Woo Oh, Jae‐Wook Kang
Publikováno v: Advanced Materials Interfaces, Vol 10, Iss 2, Pp n/a-n/a (2023)
Abstract Solution‐processed formamidinium lead iodide (FAPbI3) perovskite is entropically metastable, and it exhibits condition‐induced crystal polymorphism. Under an ambient atmosphere, the photoactive black α‐FAPbI3 converts easily to photoi

Roll-to-roll 3D printing of flexible and transparent all-solid-state supercapacitors
Autor: Manoj Mayaji Ovhal, Neetesh Kumar, Hock Beng Lee, Barkha Tyagi, Keum-Jin Ko, Shahd Boud, Jae-Wook Kang
Publikováno v: Cell Reports Physical Science, Vol 2, Iss 9, Pp 100562- (2021)
Summary: Roll-to-roll (R2R) fabrication of flexible and transparent all-solid-state supercapacitors (FT-ASSCs) is extremely challenging because of the classic trade-off between transparency and capacitance. In this work, we develop fully three-dimens

Spray-assisted deposition of a SnO2 electron transport bilayer for efficient inkjet-printed perovskite solar cells
Autor: Vinayak Vitthal Satale, Neetesh Kumar, Hock Beng Lee, Manoj Mayaji Ovhal, Sagnik Chowdhury, Barkha Tyagi, Asmaa Mohamed, Jae-Wook Kang
Publikováno v: Inorganic Chemistry Frontiers.
A mesoporous SnO2-electron transport bilayer with a high surface-area-to-volume ratio is developed for application in inkjet-printed PSCs (IJP-PSCs). The use of SnO2-bilayer has uplifted the efficiency of IJP-PSCs up to a maximum of 16.9%.

Room-Temperature Spray Deposition of Large-Area SnO
Autor: Neetesh, Kumar, Hock Beng, Lee, Rishabh, Sahani, Barkha, Tyagi, Sinyoung, Cho, Jong-Soo, Lee, Jae-Wook, Kang
Publikováno v: Small methods. 6(2)
The performance and scalability of perovskite solar cells (PSCs) is highly dependent on the morphology and charge selectivity of the electron transport layer (ETL). This work demonstrates a high-speed (1800 mm min
