“…Because the perovskite layer and the organic BHJ layer have complementary light absorption, this type of hybrid solar cell can not only reduce spectral losses but also save fabrication costs compared to typical tandem cells. Hence, organic solar cells 23 because of their narrow bandgap can be used in both heterojunction and tandem solar cells. According to their work 22 , for double-absorber solar cells, three factors have to be noticed before the fabrication process: (i) good energy bands alignment between the two absorbers layers to achieve high solar cell performance, (ii) using low-cost raw materials for commercial purpose, (iii) being toxic-free for environmental reasons.…”

Numerical simulation of an all-perovskite bilayer solar cell has been conducted by the SCAPS-1D. The presented structure employs MAPbI3 as a relatively wide bandgap (1.55 eV) top absorber and FA0.5MA0.5Pb0.5Sn0.5I3 as a narrow bandgap (1.25 eV) bottom absorber. The viability of the proposed design is accomplished in two steps. First, to validate this study, two inverted solar cells in standalone conditions are simulated and calibrated to fit previously reported state-of-the-art results. Second, both these devices are appraised for the bilayer configuration to boost their performances. Affecting parameters such as the thickness of perovskite absorbers, the work function of front and rear contacts, and the effect of temperature have been studied because solar cells are temperature-sensitive devices, and also carrier concentration and their mobility get overwhelmingly influenced as temperature increases. It is manifested that using bilayer structures could easily widen the absorption spectrum to the near-infrared region and significantly enhance the performance of the device which is mainly affected by the thickness of the FA0.5MA0.5Pb0.5Sn0.5I3 layer. Also, it has been found that the work function of the front contact has a prominent role with its optimal values being above 5 eV. Finally, the optimized inverted all-perovskite bilayer solar cell delivers a power conversion efficiency of 24.83%, fill factor of 79.4%, open circuit voltage of 0.9 V, and short circuit current density of 34.76 mA/cm2 at 275 K and a thickness of 100 nm and 600 nm for MAPbI3 and FA0.5MA0.5Pb0.5Sn0.5I3, respectively.

“…The most used material for transparent electrode is indium tin oxide (ITO) or fluoride tin oxide (FTO) which are supported on a glass substrate. [38,39] For the metal electrode, metals such as aluminum (Al), gold (Au), and silver (Ag) are mostly used as opaque electrodes. [40] In OPVs, the acceptor material can be mixed with or deposited onto the donor material to form an active layer.…”

Due to the negative impact and possible run out of fossil fuels, the use of an alternative source of energy, which is plentiful, is crucial. The use of sunlight to produce energy by means of photovoltaic cell devices is the perfect approach to deal with the disadvantages of fossil fuels. Now, the photovoltaics that are already in market because of their power conversion efficiency (PCE) and stability are based on inorganic materials. These inorganic materials are however faced with drawbacks such as toxicity and high fabrication cost. Changing inorganic materials to organic overcome those drawbacks making organic photovoltaic cells (OPVs) of importance. The problem with the OPVs is the low PCE and low stability. For decades now, researchers have been trying to improve the performance of OPVs by modifying active layer materials with the PCE of over 19% reached. This performance was achieved by performing intensive investigations to understand how the materials used in OPVs affect their performance. Our work highlights recent advancements on how the structures and chemical makeups of the active layer materials affects photovoltaic processes and performance in terms of power conversion efficiency and stability. It further sheds lights on the performance optimization of OPV and the relationship between these optimization conditions and OPV performance. The use of different substituents on the same donor or acceptor material has different optimal conditions. Furthermore, we showed how addition of different third components in the active layer have different optimal concentration point. This review also highlights and suggests a possible way to improve stability of OPVs through modification of the active layer. To date, some studies showed that incorporation of third component in the active layer led to over 97% stability after more than 1000 h.This article is protected by copyright. All rights reserved.
