Enhancement of Conversion Efficiency of CdTe/CdS p-i-n Solar Cell using TCO and BSF Layers

Alam, Md. Ashraful; Paul, Alok (East West University, 8/10/2016)

A high efficiency CdTe/CdS solar cell is designed using an intrinsic CdTe layer and a highly doped CdTe as a back surface field (BSF) layer. With the combination of TCO layer (ZnO), CdS window layer, CdTe BSF layer, the ...
Performance Evaluation of Different QAM Modulation Schemes in a VCSEL Based Single Mode Optical Link

Paul, Alok; Haldar, Dipta (East West University, 2018-02-23)

Vertical Cavity Surface Emitting Laser (VCSEL) is first demonstrated by K.Iga in 1979. Since then it creates a new era for high speed optical communication system. The most important feature of this optical device is ...
