Description
This study investigates experimentally the fundamental photovoltaic behavior and performance of a new architecture of photovoltaic cells on a flexible PET (polyethylene tetraphthalate) substrate. Fabrication of a fully functional Organic Solar Cell first involves the deposition of ITO (Indium Tin Oxide) and Orgacon™ as anode, P3HT:PCBM as the photoactive layer and finally the aluminum layer as the cathode. We then characterize the solar cell in terms of the total available surface area and power conversion efficiency (PCE). In this study, the efficiency of this new architecture of charge collectors, the effects of ITO and Orgacon™ layers as anode, comparison of 2D Vs 3D architecture and the effects of thickness of each of the layers of the organic solar cell are investigated. Further, the addition of ITO in the anodic layer and the contribution of several layers of photoactive material with tailored properties towards the overall efficiency are experimentally investigated.
