Title:  Evaluation Photovoltaic Concentrators up to 200X

Photovoltaic Concentrator is believed to have great potential to reduce the high cost associated with PV systems. But still there are certain issues which needs to be addressed which requires exhaustive information about the performance of the PV concentrator. The Objective of this project is to do the field evaluation of Photovoltaic Concentrators at varying concentration levels and at different ambient conditions so as to enable us to predict the performance of the system with good amount of accuracy.

Title: Fabrication of Silicon Nanocrystals Embedded in Silicon Nitride Matrix
Project deals with the fabrication of silicon nanocrystals embedded in silicon nitride matrix. In silicon nanocrystals band gap is tunable with its size but in normal material it is fixed. By controlling deposition parameters, size of silicon nanocrystals and hence the band gap can be changed. Techniques such as transmission electron microscopy, photoluminescence and Raman Spectroscopy can be used for characterization.

Title:Present cost of electricity from renewable and especially for solar pv needs to be reduced if they have to compete with the conventional electricity. Concentrator PV is one of the potential  technology that aims to reduce the cost/Wp of the power generated from the solar cells and thus reduce the electricity price. Low concentrator pv technology (2 Suns to 10 Suns) is a promising field that is mostly suitable for low power capacity systems (< 3kW). Applications like roof top pv- systems for residential and commercial use are in the above mention range and are mostly suited for low concentrator applications. The present paper addresses the various technological problems and solutions that are put forward by various researchers and industries regarding low concentrator pv solar cells and systems. Some new concepts are proposed which can lead to better efficiency and power output of these cells and systems.

Title :Use of Si nanocrystals for solar PVapplications
Recently, use of Si nanocrystals (Si-nC) size less than 10 nm to improve the efficiency of solar cell is interesting research area in the field of PV technology. In this project, our aim is to fabricate Si-nC embedded in Si3N4 matrix using hot wire chemical vapor deposition (HWCVD) process and to optimize the HWCVD process parameters like substrate temperature, gas flow rate, deposition time, etc. Thereby ultimate aim is to incorporate these Si-nC layers in the multijunction or p-i-n of solar cell to improve the cell performance.:

Title: Generation of Nano-Sized Si Particle with Porous Silicon (PS) Thin Film Approach
Porous Silicon became the center point of interest when its properties like photoluminescence and electroluminescence at room temperature were discovered. Quantum dots prepared from porous silicon has many useful advantages such as higher mobility, increased absorption in the red and infrared wavelength, increased stability. These properties may be used in preparation of high efficient Silicon solar cell. Aim of this project was to generate nanoparticles of silicon with porous silicon thin film approach. Work studies the process of PS thin film preparation using 1:2 HF: Acetic acid ratio with Two Step Separation. Porous Nanosized particle of silicon can be produced in a bulk using Ultrasonication method. Size can be controlled and it is observed to be in the range of 5 to 20nm. Characterization methods like TEM, AFM, Raman Shift and XRD are used to analyse the size of the particles, Strain in the particles. Effect of adding acetic acid while sonication to improve TEM imaging has also observed and analyzed using FTIR. New concepts have been proposed for production of multilayer porous silicon thin film and bulk preparation of nanoparticles using higher current density.
Scope : Concept is novel and can be used for mass production of silicon quantum dots which can be used for fabrication Quantum Dot solar cell.
Software used: VB6

Title: Solar Tubes
Solar tubes are used to transport light from one location to other, minimizing the loss of light using principle of high efficiency reflection. They can also be used to distribute natural or artificial light.
Benefits:
1. Can save up to 20-30% of total building energy consumption.
2. Brings light into inaccessible or dimly lit places.
3. Improve the internal environment without generation excessive heat.
4. Energy saving, user Satisfaction, a healthier and improved indoor environment.
