A Perovskite solar cell is a type of solar cell which includes a perovskite structured compound, most commonly a hybrid organic-inorganic lead or tin halide based material, as the light harvesting active layer. In this work solar cell based on titanium dioxide (TiO2) thin film, sensitized with methyl ammonium lead iodide (CH3NH3PbI3) perovskite are prepared. Thin films were grown on fluorine doped...
Dye-sensitized solar cells (DSCs) are currently attracting academic and commercial interest as regenerative low-cost alternatives to conventional solar cell devices. Researchers are focusing to facilitate for producing a low cost, eco-friendly and more efficient dye sensitized solar cells. Natural dye sensitized solar cells are a promising class of photovoltaic cells with the capacity of generating...
A breakthrough in solar cells is made using organolead halide perovskites as light harvesters with low-cost fabrication techniques. Perovskites are capable of high light absorbance, have excellent charge transport properties and have tunable band gaps. In this work perovskite solar cell (PSC) based on titanium dioxide (TiO2) thin film by spin coating technique is working as the anode, sensitized with...
Photovoltaics are a valuable technology in the fast forward world where energy prices are growing high within seconds. Researchers are focusing to facilitate the production of low cost, eco-friendly and more efficient dye sensitized solar cells. Natural dye sensitized solar cells are a promising class of photovoltaic cells with a capacity of generating green energy at low production cost since no...
Experimental learning plays paramount role in Physics education. Experimental physics requires phenomenological investigations in several cases and this includes understanding visible and invisible heuristic procedures to discern underlying concepts. This study investigates the invisible yet evident occurrences of physical phenomena that are difficult to grasp from a learner's perspective. In this...
In response to the Indian Ministry of Human Resource Development (MHRD) National Mission on Education through Information and Communication Technology (NME-ICT) Initiative, the Virtual and Accessible Laboratories Universalizing Education (VALUE @ Amrita) Virtual Labs Project was initiated to provide laboratory-learning experiences to college and university students across India who may not have access...
The integrability properties of a perturbed nonlinear Schrodinger equation are studied using Painleve analysis and Laxs method. We distinguish between integrability in the Painleve sense and integrability in the Lax sense. The solution of the perturbed equation, with the perturbing term depending only on time, is found by direct integration. It is seen that the perturbing nonlinear inhomogeneity can...
