Elastic perovskite solar cells, for the first time, have been realized by designing a stretchable nanostructured fiber and spring-like modified Ti wire as two electrodes with perovskite materials coated on the modified Ti wire through a solution process. The elastic perovskite solar cell appears in a fiber format and maintains stable energy conversion efficiencies under stretching.

Ion Migration

Perovskite solar cells have progressed very steadily, reaching power conversion efficiencies (PCE) beyond 20% while also improving their lifetimes up to 10,000 h. A large number of cell architecture and materials for active, transporting and electrode layers have been used, either in blends or in nanostructured layers. In this article, a set of perovskite solar cells have been designed, fabricated and characterized with special focus on their lifetime extension. The inclusion of 5-amino-valeric acid iodide (5–AVAI) as interlayer in a methyl-amino lead-iodide (MAPI) perovskite solar cell has provided additional stability in cells with PCE > 10% and T80 = 550 h. Experiments for up to 1000 h with solar cells at maximum power point under continuous illumination with solar simulator have been carried out (1 kW/m2, AM1.5G, equivalent to more than six months of outdoor illumination in locations such as Southeast Spain, with an average irradiation of 1900 kWh/m2/year). The addition of molecular additives in the bulk active layer and ETL and carbon layers not only allows better carrier transport, but also increases the stability of the perovskite solar cell by reducing ion migration within the bulk MAPI and between the different layers. Engineered interfaces with ZrO2 between the TiO2 and carbon layers contribute to reducing degradation.

T Perovskite solar cells are becoming a dominant alternative for the traditional solar cells reaching an efficiency of 25.2% in a short span of twelve years (2008-2020). Here, we are going to describe a simple process to 'put a voice on a laser beam' and transmit it over a distance via a perovskite solar cell. This process considered as a fascinating example of amplitude modulation of light using sound vibrations. Therefore, the design and simulation of the perovskite solar cell will be described in details in this work. This design is concerned about the lead-free based perovskite solar cell model with the total proposed structure “Metal contact /PEDOT:PSS/ CH3NH3SnI3/ ZnO/ SnO2:F/ Metal contact”. To study the efficiency and the performances of a solar cell, the use of well-known software so-called SCAPS-1D is undertaken to perform the system simulation. The obtained results show also the influence of the doping level of the HTM layer and absorber layer thickness on the performance of the device. So far, only the simulation part has been validated. Despite the costeffect of the system prototype, however, it could be implemented here in the laboratory as perspective work.

Perovskite Layer

Perovskite solar cells are emerging photovoltaic devices with PCE of above 25%. Perovskite are suitable light absorber materials in solar cells with excellent properties like appropriate band gap energy, long carrier lifetime and diffusion length, and high extinction coefficient. Simulation study is an important technique to understand working mechanisms of perovskites solar cells. The study would help develop efficient, stable PSCs experimentally. In this study, modeling of perovskite solar cell was carried out through Setfos software. The optimization of different parameters of layer structure of solar cell would help to achieve maximum light absorption in the perovskite layer of solar cell. Simulation study is based drift-diffusion model to study the different parameters of perovskite solar cell. Hysteresis is one of the factors in the perovskite solar cell which may influence the device performance. The measurement of abnormal hysteresis can be done by current-voltage curve during backward scan during simulation study. In backward scan, the measurement starts from biasing voltage higher than open circuit voltage and sweep to voltage below zero. The numerical simulation used to study the various parameters like open circuit voltage, short circuit current, fill factor, power conversion efficiency and hysteresis. The simulation results would help to understand the photophysics of solar cell physics which would help to fabricate highly efficient and stable perovskite solar cells experimentally.
