The research in our laboratory is focused on understanding and controlling surface and interfacial materials chemistry and applying this knowledge to a range of problems in semiconductor processing, nanotechnology, and sustainable energy. The role of interfaces becomes increasingly important as system dimensions are scaled downward. For example, most electronic and optoelectronic devices are undergoing rapid scaling, with lengths moving into the nanometer range and the surface to volume ratio becoming very large. The function of many next-generation electronic and nanoscale devices will therefore depend critically on the ability to control and modify the properties of their interfaces. One of the examples are Graphene see below
For example Graphene and fucntionalised graphene represent a promising photovoltaic technology and supercapactior. The original design includes a monolayer of graphene and functionalized graphene surfaces adsorbed on a high-porosity conducting transparent electrode (the electron transporter) surrounded by an iodine electrolyte solution (the hole conductor).
(Figure shows the representation of low cost flexible solar cells)
Functionlaised graphene surfaces/ dopant predicted to give half of the sheet resistance. The flexible organic solar cells, which will fabricated on a plastic or Zenor substrate, retained a power conversion efficiency of 2.5–2.6%, regardless of the bending conditions, even up to a bending radius of 5.2 mm. The resultant systems are characterized by X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), UV-Vis absorption spectroscopy, and synchrotron methods, and by solar cell testing techniques including photoluminescence quenching and current-voltage measurements.
|Copper indium gallium diselenide (CIGS) is one of the most promising absorber technologies for thin film photovoltaics, and variations on CIGS solar cells are currently being manufactured by several solar cell companies. Sunlight is absorbed in the CIGS layer, and the charge is extracted and transported through the buffer layer before being collected by the electrodes. The most promising buffer layer is a very thin layer of cadmium sulfide deposited via chemical bath deposition; however, due to health concerns involved with cadmium, other materials are being studied for buffer layers, and plasma enchanced chemical vapour depositon is one most promising alternatives for depositing these thin layers of n-type semiconductors. We are currently looking at new materials and methods for the buffer layer deposition in CIGS photovoltaics via PECVD and understanding the surface and interface effects through various spectroscopic techniques…|

Over the last few decades, the applications of photovoltaic systems have grown rapidly and they are on their way to become a major energy source for India and Europe. Over the past few years the installed capacity increased 200 to 400% in Asia and Europe.. The year 2016 was another one for the books for solar photovoltaic (PV) technology, as it has experienced remarkable growth over the past decade and is on the way to becoming a mature and mainstream source of electricity. For the second year in a row, in 2017 PVs were the top new source of electricity generation in the European Union. The capacity of the systems installed during this year is sufficient to cover the annual power supply needs of over 40 million European and Asian households. Each year these PV installations save more than 36 million tons of CO2. It is thus argued that reducing the EU's and Asias current rate of fossil-fuel combustion can be assisted greatly by introducing coherent, comprehensive and coordinated energy education policies. PVs continue to prove their ability to compete in the energy sector as a mainstream power generation source. However, even if the most pessimistic scenario is taken into account, PVs will continue to increase their share of the energy mix in Europe and around the world, becoming a reliable source of clean, safe and ceaseless renewable energy for all. It has been suggested that education on solar systems must be one of the priorities of the energy policy, to promote the solar energy applications for sustainable development. It is impossible to successfully promote solar systems without appropriately educated people who will be involved in their design, sizing, and installation. The main part of a PV system is the PV panel itself, as it is the part responsible for the conversion of solar energy to electricity. Thus, the theory of PV panels has been included in the curriculum of most educational institutes with an engineering course. However, it is well known how important the role of hands-on experience is in engineering education and hence, the theoretical study should be combined with experimentation in order for the students to be able to apply the theory of a specific device in actual conditions. Nowadays, the traditional approach of educational sessions in real laboratories is changing, with the virtual and remote laboratories gaining ground. This is attributed to the rapid developments and adoption of computer, internet and control technologies. A remote laboratory offers the ability to perform an extensive set of educational experiments under real conditions through the internet and within a very short time. At the same time, the student can have a live view of the systems through a web camera, offering him/her a sense of personal presence in the place where the experiment takes place. This project suggests the development of an open access remote PV laboratory for educational purposes. The remote PV laboratory, which will consist of specialized PV equipment, sensors, monitoring and control hardware, will be installed outdoors at the facilities of the OU, and allowing the users from India to perform real-world tests and experiments with photovoltaic panels over the internet, in real time. The system should be accessible by everyone on the planet with an internet access . It also should be accompanied by appropriate educational material, for several target groups, such as students, postgraduates, professionals and educators, allowing it to be used by a broad variety of users directly. The design should also be modular, to be easy to modify and or upgrade.
In addition to teaching on Open University modules our academics are engaged in ground breaking research that benefits individuals and society.
