The relationship between Solar Cell and Chemical Engineering Researchers aim at developing technologies that will see high-performance solar cells with reduced cost per watt generation. The focus is on the mass production of relatively cheap, long-lasting solar cells composed wholly of solid-state components. Dye-sensitive solar cells are an option for crystalline semiconductor photovoltaic. They consist of cheaper porous titanium dioxide nano-particles consisting of a dye absorbing sunlight coat that usually touches the liquid electrolyte. The dye-sensitive solar cells have low-cost manufacturing processes. However, they lack long life and durability which is a factor of the corrosive solution that is highly volatile and likely to leak and also high probability of reacting with the dye. This has prompted researchers to devise a method of replacing the liquid electrolyte with a non-corrosive solid-state match. A group of researchers at Purdue University are working towards coming up with an alternative solution to photovoltaic advancement through producing cheap solar cells. This will utilize some special ink on supporting materials. The team of engineers is driving massive producing solar cells at low cost. They see the possibility through making special ink using nanocrystal made of copper, zinc, tin and sulfide (CZTS). The availability of CZTS makes the printing process of the photovoltaic cells is not expensive when using ink. For the innovation to match the current technology, the solar cells should have the capacity of yielding terawatts of electricity at 50 cents per peak watt. The procedure for developing solar cells entails making nanocrystals, carefully devising the ink and printing it on a flexible supporting material. As the ink moves, the solar cells catch the heat to temperatures of 500 degrees Celsius to combine the nanoparticles. The ink technology assures a reduced cost of the solar cells and offers them a long life. Solar simulator tester: How the Instrument is working, what is the data extracted, advantages and disadvantages The solar Cell Efficiency technique looks at various compositions (semiconductors) of solar cells. Producing a solar cell involves doping or contaminating a semiconductor to produce either positive or negative charge carriers from semiconductor materials. In practical application, solar cell efficiency looks at the “ratio between electric power delivered to the load and incident of the light intensity” (Lewis Research Center 40). Solar simulator tester gauges and sorts photovoltaic cells. Modern solar simulator testers based on computer applications measure the electric performance of photovoltaic cells under simulated sunlight. It also monitors the intensity of the sunlight. Solar simulator tester measures and shows some of these cell aspects. These include open-circuit voltage (Voc), cell efficiency, fill factor (FF), short-circuit current (Isc), complete I-V curve, peak power (Pmp), cell temperature ( 0 C), shunt resistance (Rsh), short-circuit current density (Jsc), and series resistance (Rs). The data obtained falls under measurement parameters of IV curve, Isc, Voc, Im, Vm, Pm, FF, RS, EFF. Modern solar simulator tester has the benefit of providing consistent illumination on the solar cell, and they can reduce the built up of the heat and prolong the life of the solar cells.
