Solar technology is a necessary component of the movement toward renewable energies. The major part of today’s solar electricity generation is provided by photovoltaic (PV) facilities. However, the total share of photovoltaics in the global electricity generation is still very little. A reduction in the module and balance of system costs can help PV to increase its share of energy generation among other renewables. For this prospect, thin film solar technology is likely a suitable candidate.
Organic photovoltaics (OPV) is one of the emerging thin film solar technologies that utilize earth abundant materials and hold promise for cost reduction because of flexibility and light weight. However, organic solar cells need to overcome their current limitations in terms of power conversion efficiency (PCE), stability and manufacturability to secure a serious place in the PV market.
By investigating a strategy for enhancing the dielectric constant of organic semiconductors, studying the reliability of the dielectric constant characterization method and exploring morphology optimization routes for efficient solar cells, this thesis covers a complete pathway from material design to implementation.
