Photoelectrochemical Solar Cells

The solar cells have been used as most promising device to convert light energy into electrical energy. In this paper authors have attempted to fabricate Photoelectrochemical solar cell with semiconductor electrode using TMDCs. The Photoelectrochemical solar cells are the solar cells which convert the solar energy into electrical energy. The photoelectrochemical cells are clean and inexhaustible sources of energy. The photoelectrochemical solar cells are fabricated using WSe2crystal and electrolyte solution of 0.025M I2, 0.5M NaI, 0.5M Na2SO4. Here the WSe2crystals were grown by direct vapour transport technique. In our investigations the solar cell parameters like short circuit current (Isc) and Open circuit voltage (Voc) were measured and from that Fill factor (F.F.) and photoconversion efficiency (η) are investigated. The results obtained shows that the value of efficiency and fill factor of solar cell varies with the illumination intensities.

Since the temperature of a photovoltaic (PV) module is not consistent as it was estimated at a standard test condition, the thermal stability of the solar cell parameters determines the temperature dependence of the PV module. Fill factor loss analysis of crystalline silicon solar cell is one of the most efficient methods to diagnose the dominant problem, accurately. In this study, the fill factor analysis method and the double-diode model of a solar cell was applied to analyze the effect of J01, J02, Rs, and Rsh on the fill factor in details. The temperature dependence of the parameters was compared through the passivated emitter rear cell (PERC) of the industrial scale solar cells. As a result of analysis, PERC cells showed different temperature dependence for the fill factor loss of the J01 and J02 as temperatures rose. In addition, we confirmed that fill factor loss from the J01 and J02 at elevated temperature depends on the initial state of the solar cells. The verification of the fill factor loss analysis was conducted by comparing to the fitting results of the injection dependent-carrier lifetime.

ABSTRACTMeasurements with the CELLO (solar cell local characterization) technique in the LBIC (laser beam induced current) mode under dark conditions with various constant bias voltages are used to analyze the lateral distribution, and mean values, of photocurrent response maps. Local solar cell defects such as local shunts were found to have a characteristic bias voltage dependence: At negative and small positive voltages a local shunt resistance gives less current response than the adjacent area. Upon applying higher positive voltages, a transition of the mean value to lower current response and an inversion of the local defect characteristics are found. These results were modeled by a newly introduced three dimensional (3D) equivalent circuit model of a solar cell divided into subcells.Measurements and simulations of solar cells with various local defects show our method to be a new powerful tool for the quantitative analysis of local solar cell defects.

Ito Films

Nanostructure ITO thin films have been deposited on well cleaned glass and silicon substrates using dc magnetron sputtering technique. The ITO films are post annealed in air using a normal heater setup in the temperature range 100 - 400 °C. The ITO film annealed at 300°C exhibited optimum transparency and resistivity values for device applications. The thickness of the ITO thin films is determined using DEKTAK stylus profilometer. The sheet resistance and resistivity of the ITO films were determined using four probe technique. Finally, the optimized nanostructure ITO layers are incorporated on silicon solar cells and the efficiency of the solar cell are found to be in the range 12-14%. Other solar cell parameters such as fill factor(FF), open circuit voltage(Voc),Short circuit current(Isc), series resistance(Rs) and shunt resistance(Rsh) have been determined. The effect of ITO film thickness on silicon solar cells is also observed.

Abstrak- The study about fill factor and efficiency solar cell have been done with an automatic drive machine that rotates the surface of the solar cell following the movement of the light source from 0° up to 90° compared without automatic drive.  The test results are then implemented to determine the fill factor and efficiency in variations in light intensity. In this study, polycrystalline solar cell type (99 × 69) mm2, the Philips 100W/220V light bulb at a distance of 18 cm and the driving machine is controlled through an Arduino Uno R3 microcontroller. Data acquisition of current and voltage is carried out with the help of DCP-BTA current and VP-BTA voltage probes that are connected to the mini labquest transducer and displayed to a computer through loggerpro software. The result show that it has been successfully designed an automatic driver of a solar panel (99 × 69) mm2  with an Arduino Uno R3 microcontroller and a logger pro software as data acquisition software. The using solar cell automatically driven can improve the accuracy and precision of current and voltage readings so the fill factor might be increased up to 10% while the efficiency of solar cells does not change. Variations in light intensity can increase the fill factor and efficiency of solar cells. Fill factor and efficiency have an exponentially relationship to light intensity.

We have investigated the effect of diluting treatment of poly (3,4-ethylenedioxythiophen e):poly (styrene sulfonate)(PEDOT:PSS) solution on the PEDOT:PSS films and the organic polymer solar cells based on poly [4,8-bis (5-(2-ethylhexyl) thiophen-2-yl) benzo [1,2-b;4,5-b0] dithiophene-co-3-fluorothieno [3,4-b] thiophene-2-carboxylate](PTB7-Th):[6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) using PEDOT:PSS polymer as the hole transport layer. The diluted PEDOT:PSS solution by water with 1:1.5 volume ratio was used to fabricate the hole transport layer in the organic solar cell, the fill factor and the shunt resistance of the solar cell can be significantly enhanced compared with the control cell, up to 64% and 949.03Ω·cm2, respectively.
