“…Some part of the cell is devoid of radiations because of metal contacts for the collection of charges on the top of the cell and termed as metal coverage losses. Such losses can be reduced by using transparent electrodes such as Indium tin oxide [14].…”

With increasing population and industrialization, interest in energy is expanding day by day. Knowing the limitations of fossil energy, a lot of researchers are continuing to investigate the different wellsprings of energy. Among different energy sources, for example, sun-oriented energy, wind energy, tidal energy, and biomass energy: Solar energy is the most appealing as the sun is the enormous source of energy. Solar energy can be utilized to produce power legitimately, utilizing photovoltaic cells, or can be utilized as warm energy. Immense exploration is going on in the field of sun-powered photovoltaic cells and still, there is a great scope of extension to increase the effectiveness of solar cells and henceforth decreasing the expense of non-renewable energy. The various factors such as cell Geometry, numbers of absorbing layers, heat generated, and other forms of energy loss affect the efficiency of cells. This paper revolves around the different innovative approaches to investigate several types of losses to increase the productivity of solar cells.

The power conversion efficiency (PCE) of a hybrid bulk hetero-junction organic solar cell with an active layer of a blend of PBDT TS1 (donor) and PCBM (acceptor) incorporated with copper zinc tin sulfide (CZTS) quantum dots (QDs) and zinc oxide (ZnO) nanowires is simulated. It is found that the incorporation of CZTS-QDs of a single radius (1.5 nm) enhances the PCE from 9.1% to 12.34% and of 13 different radii CZTS-QDs elevates PCE to 14.96%. This enhancement occurs mainly due to the enhancement in absorption that enhances short-circuit current density (J sc ) and fill factor (FF). Finally, a layer of ZnO nanowires is added on top of the glass to reduce the reflection losses and absorption of ultraviolet light in the active layer that causes degradation and reduces the stability of organic solar cells (OSCs). The hybrid structure, thus simulated, has an enhanced PCE of 16.32% and is expected to be relatively more stable. It is expected that the results of this simulation may inspire all researchers interested in the fabrication of highly efficient hybrid OSCs.

“…with lowering the conversion efficiency of cadmium sulphide/cadmium telluride (CdS/CdTe) -based solar cells. The predominant loss of ~15% of the attainable shortcircuit current density J sc of the fabricated cells is associated with the parasitic absorption of the buffer and/or the window layer [127][128][129]. Based on literature and other experimental work later discussed in Chapter 6, parasitic absorption can be reduced through buffer and/or window layer thickness optimisation [38,130,131].…”

“…Based on literature and other experimental work later discussed in Chapter 6, parasitic absorption can be reduced through buffer and/or window layer thickness optimisation [38,130,131]. While reflection losses at the air-glass, glass-transparent-conducting-oxide (TCO), TCO-CdS, and CdS-CdTe accounts for ~8% loss of the attainable J sc of the fabricated solar cells [127][128][129]. Reflection losses are reducible to <2% using antireflection coatings [132].…”
