“…To describe the behavior of BHJ solar cells, the single diode model and more complicated models have been proposed. Although good correlation was obtained between data and the diode model, [8][9][10] systematic studies of the effect on the diode characteristics of each component and of different processing conditions are lacking. In particular, a systematic study of the effect of TiO x on the diode characteristics of BHJ solar cells has not yet been carried out.…”

The (dark) diode characteristics of the organic bulk heterojunction solar cell based on the phase separated blend of poly[N-9″-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thenyl-2′,1′,3′-benzothiadiazole)] with [6,6]-phenyl C70-butyric acid methyl ester have been analyzed with a focus on the effect of the titanium suboxide (TiOx) electron transport layer. The addition of the TiOx layer into the device structure causes the saturation current density to decrease by a factor of 26 and the shunt resistance to increase by a factor of 12. The diode ideality factor and series resistance are, respectively, almost the same for diodes made with and without the TiOx layer. The results indicate that the TiOx layer increases the energy barrier for hole transport and reduces the minority carrier density.

This paper presents a model of a distributed generation system that could operate both autonomously and connected with the grid. Mathematical models of the distributed energy resources were used to study the dynamic behavior of the interconnected system that includes a three-level control system. State-space models for entire grid-connected system were developed and the small-signal stability of the system was studied. All models were built using MATLAB/Simulink and numerical simulations were used to verify and validate the models as well as the operation of the controlled system.

“…The conventional equivalent circuit models [9,10] of Si-based solar cells obviously cannot reasonably interpret the S-shaped kink observed in OSCs, because the constant photo-generated current source, in parallel with a single diode, only represents the J-shaped I-V curves. Among the multiple-diode equivalent circuit models [11][12][13][14][15][16][17], Mazhari's model [11] is regarded as the simplest model including seven parameters used in simulations, while the other models [12][13][14][15][16][17] contain at least eight fitting parameters.…”

An improved lumped-parameter equivalent circuit model is proposed to describe S-shaped I-V characteristics of organic solar cells (OSCs). This model originates but differs from Mazhari's model. As a minor but important modification, a shunt resistance is added to Mazhari's model to increase the accuracy of simulating the S-shaped kink in the third quadrant. Subsequently, we present a terminal current-voltage equation set and derive an analytical solution to the improved model. Furthermore, we verify the analytical solution to our model by using the least square method and validate our model by using the experimental I-V curves examined from OSCs. Compared with Mazhari's model, our model has greater accuracy in interpreting the S-shaped kink with linear-like rise in the third quadrant. As a result, our improved model is suitable to explain the S-shaped I-V characteristics of organic solar cells in the whole operational region, especially for the S-shaped kink in the third quadrant.
