AbstractOver the last decade, nanotechnology and nanomaterials have attracted enormous interest due to the rising number of their applications in solar cells. A fascinating strategy to increase the efficiency of organic solar cells is the use of tailor-designed buffer layers to improve the charge transport process. High-efficiency bulk heterojunction (BHJ) solar cells have been obtained by introducing hollow core polyaniline (PANI) nanofibers as a buffer layer. An improved power conversion efficiency in polymer solar cells (PSCs) was demonstrated through the incorporation of electrospun hollow core PANI nanofibers positioned between the active layer and the electrode. PANI hollow nanofibers improved buffer layer structural properties, enhanced optical absorption, and induced a more balanced charge transfer process. Solar cell photovoltaic parameters also showed higher open-circuit voltage (+ 40.3%) and higher power conversion efficiency (+ 48.5%) than conventional architecture BHJ solar cells. Furthermore, the photovoltaic cell developed achieved the highest reported efficiency value ever reached for an electrospun fiber-based solar cell (PCE = 6.85%). Our results indicated that PANI hollow core nanostructures may be considered an effective material for high-performance PSCs and potentially applicable to other fields, such as fuel cells and sensors.

Current Research Interest

Considering the current research interest in Organic / Inorganic (ZnO) hybrid solar cells structures in developing advanced photovoltaic devices, three different types of solar cell structures are proposed. In the proposed structures, hybrid solar cell composed of ZnO nanoparticles are used as an electron-acceptor material and PEDOT:PSS is intruded in between the nanoparticles, which reported to possesses power-conversion efficiency in excess of 8%. The use of p-ZnO layer results to improve the device performance on the rigid substrate. The power-conversion efficiency of the developed solar cell was found to be as high as 10% when measured under AM 1.5G illumination. Further, simulations have been carried out whose results are in line with experimental results.
