Energy production & consumption as well as their environmental sustainability are some of the important issues that our world has to face in the 21st century. With the increase of population, contamination of environment due to generation of conventional energy has become a global crises. It is expected that the need of energy supply will be doubled by the year 2050. To resolve this situation advance technologies for both energy conversion (like solar cell, fuel cell) and storage (super capacitor & batteries) are studied extensively among the various forms of energy available. Solar energy is the most abundant & low cost energy form. Solar radiation is renewable & available for maximum duration most of the time of the year in India. Like all the other devices, performance of energy and conversion devices depend strongly upon the properties of the material they employ. This centre is aiming to lay a scientific foundation for basics of production of nano-structured and bulk material. The characterization and material preparation facilities available at the centre will facilitate the development and in-situ determination of merits/demerits of the material prepared. This will facilitate the accelerated efforts of the scientific manpower available in the state of Rajasthan. We are extensively working in different areas of the development and characterization of material for energy conversion and storage platform

Current projects and associates

The group is extensively working in different areas of the development and characterization of material for energy conversion and storage platform. At VGU we have a team of about 20+ PhD scholars and faculty members actively engaged in the development of materials for energy storage and applications.

The various themes on which groups are working are as under:

1. Novel photochemical material system: We have been working on development of nano-composites based on carbon nanotubes and their functional derivates to enhance photo absorption in different spectral range controlling their dispersal & alignment. The energy conversion and storage aspects are characterized using size/surface depended properties like morphological/electrical/optical & mechanical. A number of scholars are working in this area

2. Multi functional material for energy application: Development of metal oxide polymer composite has been a continuous activity at our centre. Development of these composites have attracted our interest because of their potential applications in octo-Electronic devices, transparent conducting electrodes in solar cell, gas sensors, flat panel displays etc. We have been focusing on polyaniline and PANI-ZnO composites. Doping of these polymers with metal oxide has resulted into some device level outputs. A few scholars have been working on this area extensively.

3. Material for energy conversion & storage: Energy saved is energy produced, hence harvesting of waste energy is also an emerging field of research. In most of the energy conversion processes about 2/3 part is lost as heat, which provides a good opportunity for use of thermoelectric device development. These devices can convert waste heat into electricity along with the advantages like no moving parts, lack of noise, higher reliability & effective operation in hostile environments without maintaince. So, it is necessary to work upon the improvement of efficiency of Thermo-electric devices which not only require exploration of the more efficient materials but also development of the tailored material with definite properties. A few scholars have been working on this area extensively.

1 Ankit Kr. Gupta Development & Study Of Filler Reinforced Polymeric Composites Suitable For Electromagnetic Shielding Minal Bafna Agarwal PG College
6. Smart materials for energy applications: Current Photovoltac technology is mostly based on Silicon wafer technologies which rely on indirect band gap absorber material, which makes use of a thick layer of absorbing material necessary. High efficiency solar modules require perfect CRYSTAL. So alternate technologies are explored worldwide. These areas based on direct band gap material such as Copper Indium Gallium Diselenide (CIGS), Copper Indium Dyselenide (CIS) etc. but these have toxic materials. Hence recent attention has been focused on materials which are non toxic, low cost and earth abundant like CZTS & CZTSe. A few students of our groups have been working on these system.
