    Computer Aided Circuit Design for Diagnosis of Dust Impact on Solar Panels

    By Rashmi Chawla, Anisha Raheja, Divya Khanna

    Abstract: AbstractSolar panels have come up as a promising methodology for extracting solar energy and yielding electricity. However, there exist many barriers in its path to become an indispensable part of today's era. The decreasing panel efficiency due to several factors such as temperature, irradiance, photoactive material, dust, panel orientation, is an issue of concern. Amongst these, dust is the least acknowledged, yet the most crucial parameter responsible for deteriorating panel …

    Evolution of Graphene Oxide : A Survey

    By Rashmi Chawla, Heena Verma, Ashank Upadhyay

    Abstract: Graphene, first isolated in 2004, is the 2D material that captivated researchers’ attention due to its extraordinary properties. These extraordinary properties motivated researchers to keep on searching better ways for synthesis of Graphene oxide (GO) and reduced graphene oxide (rGO). Several synthesis(oxidation-reduction) mechanisms are available in literature such as: Staudenmaier’s(ST), Hofmann’s (HO), Hummers’ (HU), Modified Hummer’s (MHU), improved Hummers’(IHU) and Mild Oxidation(MO) methods for oxidation and thermal, chemical, hydrothermal and …

    Comparative Analysis of Perturb & Observe and Incremental & Conductance MPPT Algorithms

    By Minakshi Sharma, Rashmi Chawla, Pradeep Kumar

    Abstract: AbstractMaximum power point tracking (MPPT) technique implemented on a Photo-Voltaic (PV) system is meant for increasing its efficiency. In literature may research work claims MPPT technique as one of the most efficient way in enhancing output power generated. The output electrical parameters (V-I curve) of PV (photovoltaic) system depends on the irradiance, temperature, configuration, environmental conditions and analogy of a PV system. MPPT regulates the system at the reference voltage …

    Interface Engineering of Graphene Multi-Junction InGaP/GaAs/InGaAs/Ge Solar PVC

    By Rashmi Chawla, Poonam Singhal, Amit Kumar Garg

    Abstract: AbstractThe main impediment faced by solar Photo-Voltaic Cell (PVC) is the excitation of charge carriers by high and low energy photons to make them reach the conduction band as this superintends the output device current. To enhance the device current, intermediate engineering of solar PVC is the most prominent strategy. An Inter-Mediate Layer (IML) serves as a spectrally selective layer between the muti-junctions for tandem solar cell. This research work …

    Mathematical Model and Analysis of Dual Axis Solar Tracking Mechanism

    By Nilay Srivastava, Rashmi Chawla

    Abstract: AbstractThe recent years have seen solar energy as one of the most potential candidate for electric power generation. However, the low output conversion efficiency still remains the matter for concern. The maximum power energy output relies on myriad environmental factors. This paper investigates the role of radiation intensity and panel position for better output efficiency and proposes an efficient dual axis solar tracking mathematical modelling that tracks the sun irrespective …
