Journal ArticleDOI
Highly stable and efficient all-inorganic lead-free perovskite solar cells with native-oxide passivation.
Min Chen,Ming-Gang Ju,Hector F. Garces,Alexander D. Carl,Luis K. Ono,Zafer Hawash,Yi Zhang,Tianyi Shen,Yabing Qi,Ronald L. Grimm,Domenico Pacifici,Xiao Cheng Zeng,Yuanyuan Zhou,Nitin P. Padture +13 more
TL;DR: The native-oxide passivation approach reported here represents an alternate avenue for boosting the efficiency and stability of lead-free PSCs, and develops inorganic cesium tin and germanium mixed-cation perovskites that show high operational stability and efficiency over 7%.
Journal ArticleDOI
Earth-Abundant Nontoxic Titanium(IV)-based Vacancy-Ordered Double Perovskite Halides with Tunable 1.0 to 1.8 eV Bandgaps for Photovoltaic Applications
Ming-Gang Ju,Min Chen,Yuanyuan Zhou,Hector F. Garces,Jun Dai,Liang Ma,Nitin P. Padture,Xiao Cheng Zeng +7 more
TL;DR: In this paper, a promising new family of all-inorganic perovskite (HP) light absorbers based on the nontoxic, earth-abundant, ultrastable Ti(IV) for use in PSCs is reported, which possess a combination of several desirable attributes including suitable bandgaps, excellent optical absorption, benign defect properties, and high stability.
Journal ArticleDOI
Water Oxidation Catalysis using Amorphous Manganese Oxides, Octahedral Molecular Sieves (OMS-2), and Octahedral Layered (OL-1) Manganese Oxide Structures
Aparna Iyer,Joselyn Del-Pilar,Cecil K. King’ondu,Edward Kissel,Hector F. Garces,Hui Huang,Abdelhamid M. El-Sawy,Prabir K. Dutta,Steven L. Suib +8 more
TL;DR: In this paper, mixed valent porous amorphous manganese oxides (AMO), along with cryptomelane type tunnel MANGANESE oxides and layered birnessite (OL-1) have been used as water oxidation catalysts.
Journal ArticleDOI
Heterojunction-Depleted Lead-Free Perovskite Solar Cells with Coarse-Grained B-γ-CsSnI3 Thin Films
Ning Wang,Yuanyuan Zhou,Ming-Gang Ju,Hector F. Garces,Tao Ding,Shuping Pang,Xiao Cheng Zeng,Nitin P. Padture,Xiao Wei Sun,Xiao Wei Sun +9 more
TL;DR: In this paper, a coarse-grained B-γ-CsSnI3 perovskite thin films are used as light absorber for efficient lead-free PSCs.
Journal ArticleDOI
Long Minority‐Carrier Diffusion Length and Low Surface‐Recombination Velocity in Inorganic Lead‐Free CsSnI3 Perovskite Crystal for Solar Cells
Bo Wu,Yuanyuan Zhou,Guichuan Xing,Guichuan Xing,Qiang Xu,Hector F. Garces,Ankur Solanki,Teck Wee Goh,Nitin P. Padture,Tze Chien Sum +9 more
TL;DR: In this article, it is revealed that melt-synthesized cesium tin iodide (CsSnI3) ingots containing high-quality large single crystal (SC) grains transcend these fundamental limitations.
