Design and optimization of thin film organic solar cells

The aim of this Ph.D. project was to undertake a systematic study to develop a technique for improving the performance of solution-processed translucent P3HT:PCBM-based solar cells over the two competing indexes: power conversion efficiency and transmittance, for stacking up or transparency. A compr...
