This paper presents maps of spatial distributions of the short circuit current Isc(x,y) and the open circuit voltage Uoc(x,y) of the investigated low cost solar cells. Visible differences in values of these parameters were explained by differences in the serial and shunt resistances determined for different points of solar cells from measurements of I−V characteristics. The spectral dependence of the photo voltage of solar cell is also shown, discussed and interpreted in the model of amorphous and crystal silicon.

“…In the above presented equations Iph is assumed to be equal to the short circuit current (Isc). The detailed description of this method and (2-3) is presented in papers [25,26]. This method was used in this work to extract, from the experimental I−V characteristics, essential parameters of investigated solar cells.…”

“…This leads to the attractive combinations of optical and electrical properties that are relevant for improved OPV system performances. This has further led to the proposition of an optimized empirical relation for However, unlike inorganic semiconductors in which the photogenerated excitons are easily dissociated and separated into free charge carriers [1], organic excitons are strongly bound with energies of~0.4 eV [76]. Such energy values are between 0.5 and 2 eV stronger than those of the thermal energy at room temperature [77][78][79][80].…”

This study reviews and describes some of the existing research and mechanisms of operation of organic photovoltaic (OPV) cells. Introduced first are problems that exist with traditional fossil fuels that result in most of the world energy challenges such as environmental pollution. This is followed by the description of baseline organic solar cell (OSC) structures and materials. Then, some of the existing modelling approaches that have implemented either a one-or a two-dimensional drift-diffusion model to examine OSC structures are reviewed, and their reproducibility is examined. Both experimental and modelling approaches reviewed are particularly important for more and better designed research to probe practical procedural problems associated with OSCs that hinder the commercialization of OPV technology.

“…Under illumination, I ph is equal to number of dissociated excitons/s, i.e., number of free electron/hole pairs per second, immediately after generation, before any recombination takes place [21]. The shunt resistor R sh is due to recombination of charge carriers near the dissociation site (e.g.…”

In this paper, the characteristics of organic bulk heterojunction solar cells have been designed and modeled using MATLAB R2010a version. Here, organic solar cell is considered as a diode and an equivalent circuit is developed with series and shunt resistances to obtain the I-V characteristics of the model. Non-linear equations are obtained in by solving the equivalent circuit model. These non-linear equations are solved using Newton-Raphson method. The theoretical results thus obtained are compared with practical results and an observation made is that are theoretical results are close to the results obtained from fabricated structure.
