  Modeling and Simulation of n-ZnO/i-ZnO/Si p-i-n Heterojunction Solar Cell

  By Nidhi Sinha, Varun Chandra, Arun Dev Dhar Dwiwedi

  Abstract: This paper presents 2D numerical simulation of n-ZnO/i-ZnO/p-Si p-i-n heterojunction solar cell using commercial device simulation software ATLAS from Silvaco Inc. This work deals with the design and performance optimization of p-i-n heterojunction solar cell using two dimensional computer aided design (TCAD) tool ATLAS from Silvaco Inc. The device has been simulated and analyzed with respect to the I-V characteristics of the device in dark and illuminated condition. Further figure …

  Numerical simulation of P3HT based Organic Thin Film Transistors (OTFTs)

  By Arun Dev Dhar Dwiwedi, Rajeev Dhar Dwivedi, Raghvendra D. Dwivedi, Sumit Vyas, P. Chakrabarti

  Abstract: This paper presents numerical simulation of P3HT based organic thin film transistors using commercially available device simulation software ATLAS from Silvaco Inc. We present a model of the P3HT based OTFTs based on the tail and the deep states, which can produce well the characteristics of the P3HT based OTFTs in both the subthreshold and the above-threshold regions. Simulation includes the hopping mobility model, Poole-Frenkel mobility model, Schottky contact, and …
