Journal ArticleDOI
Microstructures of Organometal Trihalide Perovskites for Solar Cells: Their Evolution from Solutions and Characterization.
TL;DR: The challenges and opportunities in the characterization of OTP thin films are discussed for not only gaining a deep understanding of defects and microstructures but also elucidating classical and nonclassical phenomena pertaining to nucleation/growth, coarsening, and micro structural evolution in these films.
Journal ArticleDOI
TiO2–Au plasmonic nanocomposite for enhanced dye-sensitized solar cell (DSSC) performance
Subas Muduli,Onkar Game,Vivek Dhas,K. Vijayamohanan,Kashinath A. Bogle,Nagarajan Valanoor,Satishchandra Ogale +6 more
TL;DR: Anatase TiO2 nanoparticles dressed with gold nanoparticles were synthesized by hydrothermal process by using mixed precursor and controlled conditions Diffused Reflectance Spectra (DRS) reveal that in addition to the expectedTiO2 interband absorption below 360nm gold surface plasmon feature occurs near 564nm as mentioned in this paper.
Journal ArticleDOI
ZnO(N)–Spiro-MeOTAD hybrid photodiode: an efficient self-powered fast-response UV (visible) photosensor
Onkar Game,Onkar Game,Onkar Game,Upendra Singh,Upendra Singh,Tanya Kumari,Tanya Kumari,Arun Banpurkar,Satishchandra Ogale,Satishchandra Ogale +9 more
TL;DR: A facile solution-processed fabrication of a self-powered organic-inorganic hybrid photodetector using n-type oriented ZnO nanorods and p-type Spiro-MeOTAD semiconductor is reported, showing that the latter has far less toxicity than the toxic elements stated above.
Journal ArticleDOI
High-Performance Formamidinium-Based Perovskite Solar Cells via Microstructure-Mediated δ-to-α Phase Transformation
Tanghao Liu,Tanghao Liu,Tanghao Liu,Yingxia Zong,Yingxia Zong,Yuanyuan Zhou,Mengjin Yang,Zhen Li,Onkar Game,Kai Zhu,Rui Zhu,Rui Zhu,Qihuang Gong,Qihuang Gong,Nitin P. Padture +14 more
TL;DR: In this article, the authors show that having a large grain size in the non-perovskite intermediate films is essential for the growth of high-quality α-FAPbI3(Cs) HOIP thin films.
Journal ArticleDOI
CH3NH3PbI(3−x)(BF4)x: molecular ion substituted hybrid perovskite
Satyawan Nagane,Satyawan Nagane,Umesh Bansode,Umesh Bansode,Onkar Game,Onkar Game,Shraddha Chhatre,Shraddha Chhatre,Satishchandra Ogale,Satishchandra Ogale +9 more
TL;DR: A molecular ion (BF4(-)) substituted hybrid perovskite CH3NH3PbI(3-x)(BF4)x is synthesized and shows significant enhancement in electrical conductivity at low frequencies and improved photoresponse under AM1.5 illumination.
