Solar cells are a potential option to meet the growing energy requirements of humans. Organic solar cells (OSCs) represent a class of solar cells that is a part of the third generation solar cell technology. The quest for obtaining enhanced OSC efficiencies has led to the incorporation of metallic nanoparticles (NPs) in the OSCs. Metallic NPs increase the incident light absorption instances, thus increasing the obtainable cell efficiencies. Diff erent parameters and factors need to be considered for obtaining the optimum NP specifications. Investigations of the mechanism of light absorption after the introduction of NPs in the OSC are critical. Hence theoretical simulations for such OSCs are important. An overview of the different solar cell characterization techniques is presented in this paper. Simulations are carried out for these characterization techniques to study the behavior of the P3HT:PCBM based OSC in which silver NPs are incorporated in the active layer. The simulations are carried out for the cell structure in the presence of diff erent non-ideality factors. The non-idealities include mobilitylimitations, presence of traps, recombination losses, low generation, presence of non-ideal values of series and shunt resistances, the effect of doping, etc. The simulated characterization techniques can be utilized for the performance study and parameter extraction of these NP incorporated OSCs.

Organic solar cells have gathered much research interest in recent years because of their advantages like low-cost, fl exibilityand light-weight. This paper presents a fi rst of its kind, critical review of the theoretical and experimental studies performedto determine the outcome of changing active layer thickness on the working of a bulk heterojunction organic solar cell. Thefunctional principles of an organic solar cell along with its typical parameters are briefl y outlined. This paper discusses thefeatures of the active layer and response of these features to changing active layer thickness which determines the deviceperformance. Subsequently we describe the changes occurring in the parameters of the solar cell, followed by a detailedaccount of the optimal thickness ranges for diff erent bulk heterojunction solar cells. A concise description of the donor andacceptor material properties is also presented. In the last section, simulations performed by changing active layer thicknessfor two diff erent active layer material combinations have been presented, wherein we used poly(3-hexylthiophene): P3HT asthe electron donor and phenyl-C 61 -butyric acid methyl ester: PCBM as the electron acceptor for one cell and the other cellhas poly(9,9-dioctylindenofl uorene- co -benzothiadiazole): PIF8BT and N ′-bis(1-ethylpropyl)-3,4,9,10-perylene tetracarboxydiimide: PDI as donor and acceptor respectively. The paper concludes with a brief discussion of the applicability of annealingprocess to improve the optimal active layer thickness ranges of organic solar cells.
