Dye-sensitized solar cells affords a technically and economically trustworthy alternative for p -n junction photovoltaic devices which made by silicon. In divergence to the conventional photovoltaic device the task of light absorption and charge carrier transport separately functioned. Photons absorbed by a sensitizer, which is moored to the surface of a wide band semiconductor. Charge separation occurs at the interface via photo-induced electron injection from the dye into the conduction band of the solid. Charge collector collects the carriers are from the conduction band of the semiconductor. Because of broad absorption band of sensitizers it permits to yield a large fraction of sunlight. The conversion of incident photons into electric current is attained over a large spectral range from the UV region to the near IR region. Power electronics, the technology of efficiently processing electric power, plays an essential part in the integration of the dispersed generation units for good efficiency and high performance of the power system. Due to the characteristics of low cost and high efficiency, the transformer less photo voltaic grid-connected inverters have been popularized in the application of solar electric generation system in the residential market. Unfortunately, the leakage currents through the stray capacitors between the PV array and the ground are harmful. This paper presents modelling and simulation of dye sensitized solar system with hybrid transformer less inverter topologies and proved that H6 topology by using neutral point clamped (NPC)method for suppressing of leakage currents and to obtain excellent common mode voltages are the best compared to other topologies.
