The effect of position of pn junction on output current for both micro-rectangular texturing and planar surface in solar cell has been investigated by ray tracing. In geometric optic modeling, this includes finding the effect of position of pn junction on improving the efficiency. The importance of pn junction position in the textured surface of solar cells has been confirmed using the ATLAS software. Texturing improves electronic circuit analysis and design neamen pdf efficiency but the effectiveness increases with the depth of pn junction.
A textured solar cell with 40 μm depth of pn junction has the 3 times more efficiency than the same non-textured solar cell. Introducing the current variation in the voltage 0. 25 V for two surfaces supports this conclusion. Check if you have access through your login credentials or your institution. An introduction to the physics of field-effect transistors is presented, followed by a study of the properties of electrolytic solutions and electrolyte interface surface effects. Full modeling of the ion-sensitive transistor is given, followed by a survey of the different uses of the ISFET in biomedical and environmental applications.
Particular attention is given to the use of the ion-sensitive transistors as replacements for microarrays in DNA gene expression analysis. 2006 Published by Elsevier Ltd. A mathematical approach to the common types of wave motion C. Advanced Frequency Synthesis by Phase Lock william f.
