“…The journey of OPVs began with the discovery of the photovoltaic effect in organic materials. The initial breakthrough in OPVs was marked by the development of the “Tang cell” in 1986, a two-layer device comprising copper phthalocyanine and perylene diimide [ 75 ]. This discovery laid the foundation for the evolution of OPVs, leading to the concept of bulk hetero-junction (BHJ) solar cells in the early 1990s [ 75 ].…”

The evolution of photovoltaic cells is intrinsically linked to advancements in the materials from which they are fabricated. This review paper provides an in-depth analysis of the latest developments in silicon-based, organic, and perovskite solar cells, which are at the forefront of photovoltaic research. We scrutinize the unique characteristics, advantages, and limitations of each material class, emphasizing their contributions to efficiency, stability, and commercial viability. Silicon-based cells are explored for their enduring relevance and recent innovations in crystalline structures. Organic photovoltaic cells are examined for their flexibility and potential for low-cost production, while perovskites are highlighted for their remarkable efficiency gains and ease of fabrication. The paper also addresses the challenges of material stability, scalability, and environmental impact, offering a balanced perspective on the current state and future potential of these material technologies.

Organic solar cell (OSC) is one of the best promising candidate for harvesting energy mainly due to their simple and economic fabrication process, the reduced manufacturing cost, and easy integration to other products. Bulk heterojunction solar cell in which the active layer is a blend of donor –acceptor materials are one of the best organic photovoltaic device with highest efficiency and a significant improvement in the device performance occur over last years. Bulk heterojunction architecture gives a high interfacial surface area for efficient charge dissociation. In this study, bulk heterojunction solar cell is simulated using General Purpose Photovoltaic Device Model Software. A donor-acceptor blend of Zinc pthalocyanine (ZnPc) fullerene C60 is used as the active layer. The power conversion efficiency for various thickness of the active layer is studied. Optimization of active layer thickness for maximum power conversion efficiency are done. The dependence of various electrical parameters such as short circuit current density(Jsc), Open circuit voltage(Voc), fill factor (FF), average carrier mobility on power conversion efficiency are also studied.

Organic based thin film solar cells have achieved considerable power conversion efficiency (PCE). As there is a desire to the benefits of on-demand energy production, future world energy consumption will continue to rise. Bilayer organic solar cell has two active layers in between conductive electrodes. Present report, is a simulation study to compare the PCE of bilayer organic solar cells by varying one of its active layer material using General-Purpose Photovoltaic Device Model or GPVDM software. The materials used for active layer are MEH-M3EH-PPV, MEH-DOO-PPV, MEH-PPV and M3EH-PPV based on the degree of alkyl substitutions. Data of absorption spectrum, refractive index spectrum and photoluminescence spectrum are added as input and obtained the simulation results. Values of power conversion efficiencies, fill factor and other photovoltaic parameter values for each bilayer organic solar cell is obtained. Transmittance spectrum, reflectance spectrum, Current density-Voltage plot, variation of charge density and total charge density with applied voltage are attained from the simulation and compared. The results give out effect of side chain alkyl substitution on efficiency of bilayer organic solar cell. MEH-DOO-PPV with longest alkyl side chain substitution has maximum power conversion efficiency. This intuition helps to design suitable bilayer organic solar cell, which has got its relevant applications in the optoelectronics.
