P19 – Numerical Assessment of Bloch Surface Wave 1D-PhC Sensor using Ba2NaNb5O15 Defect Layer

Sagar K., Kumar A.

In this paper, a top defective layer of Barium sodium niobate (Ba2NaNb5O15) material of nanometer range thickness is used to confine Bloch surface mode at the upper interface of the proposed structure. For a 1275 nm operating wavelength, the structural characteristics are intended to stimulate a BSW at the top interface. Wavelength interrogation, angle interrogation, […]

SC04 – Performance Evaluation of Lead-Free Cs2CuSbCl6 Perovskite Solar Cells for > 21.67% Efficiency

Kumar A., Thomas M. S., Gupta N., Jain A.

This work investigates the performance of Cs2CuSbCl6-based lead-free perovskite solar cells for photovoltaic applications. Cs2CuSbCl6 has a bandgap of 1.7eV and it is a durable and non-toxic material. Cs2CuSbCl6 can absorb more photons and thus obtain high efficiency. This work has been performed using SCAPS-1D software with the focus on optimizing the absorber layer thickness […]
