The evidence of the limited global impact of PV is marked by the increasing market share of fossil fuels in the generation of electricity [1].

Notably, about 65–70% of global electricity consumption is derived mainly from exhaustible fossil fuels such as petroleum, coal, and natural gas [1, 2].

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.

Plasmonic assisted organic photovoltaics have a potential to increase the performance of devices and thus reduce the cost/k W of generating capacity.

This makes our world fossil fuel reserves unable to follow with the global energy demand, which is rising continually as a result of human population growth and development.The device with periodic gold nanostructures exhibits a broadband light absorption enhancement.In this work, the correlation between light absorption enhancements and enhanced device performance is investigated.In this work, we exemplarily model the electrical properties of organic solar cells with rectangular-grating structures, as compared to planar reference devices.Based on our numeric results, we demonstrate that, beyond an optical absorption enhancement, the device fill factor improves significantly by introducing the grating structures.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.From the simulations we conclude that enhanced carrier collection efficiency is the main reason for the increased solar cell fill factor.This work contributes towards a more fundamental understanding of the effect of nanostructured electrodes on the electrical properties of organic solar cells.Additionally, some of these places that are concentrated with fossil fuel resources are affected by geopolitical and socioeconomical instabilities [3, 4].Furthermore, the production of energy from fossil fuels is often toxic to the environment and health [5].

  1. The conceptual framework proposed for this study indicated three areas of interest: the context of parent and community involvement programs; the roles that parents, families, and community members assume in the education of their children; and the effects of promising programs on parents, students, school staff, schools, and school districts. What key resources are needed to design, develop, implement, and sustain these roles?
