Investigations of electrical and optical properties of functional TCO thin films

AbstractTransparent conducting oxide (TCO) films of indium-tin-oxide were evaporated on the surface of silicon wafers after phosphorous diffusion and on the reference glass substrates. The influence of deposition process parameters (electron beam current, oxygen flow and the substrate temperature) on optical and electrical properties of evaporated thin films were investigated by means of resistivity measurements and optical spectrophotometry. The performance of prepared thin films was judged by calculated figure of merit and the best result was obtained for the sample deposited on the substrate heated to the 100 °C and then removed from the deposition chamber and annealed in an air for 5 minutes at 400 °C. Refractive index and extinction coefficient were evaluated based on measured transmission spectra and used for designing of antireflection coating for solar cell. The obtained results showed that prepared TCO thin films are promising as a part of counter electrode in crystalline silicon solar cell construction.

Antireflection Coatings

In this report we present series of experiments during which the short circuit current of mono crystalline silicon solar cell was improved step by step so as a consequence the efficiency was increased. At first, the front contact of solar cell was optimized to reduce the shadow loss and the series resistance. Then surface treatments were prepared by TMAH solution to reduce the total light reflectance and to improve the light trapping effect. Finally, antireflection coatings were deposited to passivate the front surface either by silicon nitride thin layer or to increase the collection probability by indium tin oxide layer, and to reduce the reflectance of light. As a result, solar cells of about 13% have been obtained, with the average open circuit voltage Voc about 527mV, with the fill factor about 68% and the short circuit current about 7.92 mA/cm2 under the irradiation density of 21 mW/cm2.

Infrared Spectral

We investigated the light absorption of multi-antireflective layers on the microtextured surface of a crystalline silicon solar cell. Triple antireflection coating layers were deposited with SiNx/SiO2/SiNx thin films. A 20 nm SiO2 layer was sandwiched between two SiNx layers, forming a total thickness around 90 nm. Triple antireflection layers showed the enhanced light absorption in the infrared wavelength range, which is consistent with the Si energy band gap region. Further optical simulation on triple antireflection layers using a transfer matrix method showed similar reflection behavior to that of the experimental results. The SiO2 layer sandwiched between the SiNx thin films acts not only as the Fresnel reflection layer in the blue and UV spectral regions, but also as a photon tunneling layer in the infrared spectral region.

The Impact

Building-integrated photovoltaic (BIPV) systems represent an interesting, alternative approach for increasing the available area for electricity production and potentially for further reducing the cost of solar electricity. In BIPV systems, the visual impression of a solar module becomes important, including its color. However, the range of solar cell colours and shapes currently on offer to architects and BIPV system designers is still very limited, and this is a barrier to the widespread use of PV modules as a constructional “material.” The color of a solar module is determined by the color of the cells in the module, which is given by the antireflection coating (ARC). However, access to efficient, but differently colored, solar cells is important for the further development of BIPV systems. In this paper, we have used Diamond-like nanocomposite layer as an Antireflective Nanocomposite based (ARNAB) coating material for crystalline silicon solar cell, and the impact of varying the color of an ARC upon the optical characteristics and efficiency of a solar cell is investigated. In addition to a comparison of the optical characteristics of such solar cells, the effect of using colored ARCs on solar cell efficiency is quantified using the solar cell modeling tool PC1D.

Pv Module

Rising temperatures significantly affect the PV module, decreasing its voltage and lowering output power. Furthermore, temperature rises have been linked to several PV module failures or degradation modes. The purpose of this study analyzes polyvinyl alcohol PVA on crystalline silicon solar cells as a thermal insulation thin film. PVA thin films were prepared by dip-coating technique with a thickness of 1.15μm. The films exhibit suitable solar cell temperature controlling though it's an effect on masking the ultraviolet wavelength. The maximum temperature variation on the coating solar cell's surface was 4.5 °C as a comparison to a bare solar cell with irradiate exposure time 1800sec, and maximum efficiency obtained 18.99% in which Voc = 0.566 v and Isc = 330.2 mA when compared with bare solar cell 15.07% with benefit efficiency +3.92%. The concentrations of the polyvinyl alcohol influences on thin films and their effect on solar cell parameters are discussed.
