G. Rajendra Kumar,A. Dennyson Savariraj,S. N. Karthick,S. Selvam,B. Balamuralitharan,Hee-Je Kim,Kodakkal Kannan Viswanathan,M. Vijaykumar,Kandasamy Prabakar,Kandasamy Prabakar +9 more
TL;DR: A detailed analysis of the phase transition kinetics and binding energy states of solution processed methylammonium lead iodide (MAPbI3) thin films prepared at ambient conditions and annealed at different elevated temperatures is presented.
Journal ArticleDOI
Influence of Cu vacancy on knit coir mat structured CuS as counter electrode for quantum dot sensitized solar cells.
TL;DR: From the UV-vis absorption spectra, it is observed that CuS thin film exhibits free carrier intraband absorption in the longer wavelengh region and the enhanced performance of CuS counter electrodes is due to Cu vacancies with increased S composition.
Journal ArticleDOI
CuS nano flakes and nano platelets as counter electrode for quantum dots sensitized solar cells
TL;DR: A facile chemical bath deposited (CBD) CuS nanoflakes and nano platelets are used as an effective counter electrode (CE) for quantum dot sensitized solar cells (QDSSC) and the effect of seed layer assistance has been discussed as mentioned in this paper.
Journal ArticleDOI
Efficiency and resolution of HPGe and NaI(Tl) detectors using gamma-ray spectroscopy
TL;DR: In this paper, the energy dependence of efficiency and resolution of HPGe and NaI(Tl) detectors using gamma-ray spectroscopy was investigated, and it was found that the resolution of the detector was directly proportional to the energy of gamma-rays and its efficiency was exponentially proportional to gamma radiation energy.
Journal ArticleDOI
