“…Numerous strategies have been used to continually improve the performance of BHJ thin film organic solar cells. Some of these strategies include the synthesis of efficient new donor and acceptor polymer molecules, − fine-tuning of morphology and mesoscopic aggregation of molecules in the photoactive layers, , the stacking of multiple active blends-tandem solar cells, optimization of the donor–acceptor concentration in the absorber layer, the use of solvent additives and choice of host solvents − and the incorporation of a third component to influence the properties of charge transport layers positively. − The third components often employed in the various layers of conventional and inverted device architectures of organic solar cells including metallic nanoparticles, plasmonic nanocomposites, and semiconductor quantum dot (SQDs) are found to have a significant influence on carriers’ dissociation, charge transfer, photon harvesting processes, and reducing energy loss for enhanced power conversion efficiencies. − …”

Core−shell semiconductor quantum dots (SQDs) were synthesized via the microwave irradiation method from cadmium and zinc sulfides (Cd x S/ Zn 1−x S). The SQDs were incorporated into the electron transport layer of thin film polymer solar cells (TFPSCs) to assist in light trapping and charge collection processes. The up and down conversion of radiation in SQDs is expected to boost absorption between the lower energy bandgap core and wide energy bandgap shell, respectively. The investigation employs apolymers blend consisting of a poly [[4,8bis[(2-ethylhexyl) [3,4-b]thiophenediyl]]:[6,6]-phenyl C 71 butyric acid methyl ester (PTB7:PC71BM) as a photoactive medium of the solar cells. Consequently, the experimental evidence suggested that the inclusion of SQDs significantly improved the power conversion efficiency (PCE) of the solar cell as a result of increased energy transfer, exciton generation, and charge collection processes in TFPSCs. Furthermore, the performances of the solar cells are found to be dependent on the concentration of the SQD in the transport layer, where the highest PCE of 7.13% was measured at an optimal concentration of 0.375 wt %. This is an important development of the investigation with a recorded increment in PCE by nearly 23% from the reference cell.

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.
