“…A significant effort in photovoltaic research today is objectively to enhance PCE, while simultaneously reducing cost [15]. The overwhelming majority of today's PV market consists of three types of generation [16]: the first-generation PV is siliconbased solar cell modules, which currently dominate the solar power market due to their low-cost and long-term reliability, but only convert about 8-19% of the available solar power [17]. Second-generation PVs are thin-film solar cells that aim to decrease cost by utilizing less material and depositing on inexpensive substrates, such as metal foil, glass, and plastic.…”

Nanowires (NWs) are 1D nanostructures with unique and wonderful optical and electrical properties. Due to their highly anisotropic shape and enormous index of refraction, they behave as optical antennae with improved absorption and emission properties, and thus better photovoltaic cell efficiency compared to a planar material with equivalent volume. Implying important advantages of reduced material usage and cost as well as due to its direct bandgap and its flexibility for designing solar cells, we choose to review III–V NWs. Their bandgap can easily be tunable for growing on the cheapest Si substrate. The recent developments in NW-based photovoltaics with attractive III–V NWs with different growth mechanisms, device fabrication, and performance results are studied. Recently, III–V NW solar cells have achieved an interesting efficiency above 10%. GaAsP NW has achieved 10.2%; InP NW has achieved 13.8%; GaAs NW has achieved 15.3%; and moreover the highest 17.8% efficiency is achieved by InP NW. While the III–V NW solar cells are much more vital and promising, their current efficiencies are still much lower than the theoretically predicted maximum efficiency of 48%. In this review, the chapter focused on the synthesis processes of III–V nanowires, vapor-liquid-solid growing mechanisms, solar light harvesting of III–V nanowire solar cells, and designing high-efficiency and low-cost III–V nanowire solar cells.

“…Solution-processed bulk-heterojunction (BHJ) photovoltaics constitute a subcategory of OSCs that already enjoys immense research. The careful selection of polymer donor and fullerene acceptor materials, having in mind the proper energy level matching and appropriate degree of phase separation inside the blend, has introduced additional degrees of freedom into OSC research and scientific advancement [14][15][16]. Polymers, including P3HT [17] and PTB7 [18], as well as fullerene derivatives with most notable PC 61 BM [19] and PC 71 BM [20] have been under study for years while demonstrating exceptional efficiencies (>5%) for P3HT:PC 61 BM [21] and above 7% for PTB7:PC 71 BM based devices [22].…”

A conjugated, ladder-type multi-fused ring 4,7-dithienbenzothiadiazole:thiophene derivative, named as compound ‘T’, was for the first time incorporated, within the PTB7:PC71BM photoactive layer for inverted ternary organic solar cells (TOSCs) realization. The effective energy level offset caused by compound T between the polymeric donor and fullerene acceptor materials, as well as its resulting potential as electron cascade material contribute to an enhanced exciton dissociation, electron transfer facilitator and thus improved overall photovoltaic performance. The engineering optimization of the inverted TOSC, ITO/PFN/PTB7:Compound T(5% v/v):PC71BM/MoO3/Al, resulted in an overall power conversion efficiency (PCE) of 8.34%, with a short-circuit current density (Jsc) of 16.75 mA cm−2, open-circuit voltage (Voc) of 0.74 V and a fill factor (FF) of 68.1%, under AM1.5G illumination. This photovoltaic performance was improved by approximately 12% with respect to the control binary device.

“…In recent years, organic photovoltaics (OPVs) have attracted worldwide attention from the scientific community due to their promising characteristics including low-cost manufacturing procedures, attainable flexibility, and toward large-scale industrial applications, Nevertheless, the conversion efficiency of state-of-the-art OPVs was still less than 15%, which remained insufficient for the practical operation needs in current mobile electronics. − Also, the drawbacks in manufacturing aspects laid in poor stability under the long-term operation and were subjected to efficiency degradation due to environmental deterioration. By contrast, crystalline silicon (Si) solar cells, the dominant commercialized photovoltaics, enabled one to push the practical limit efficiency approaching the ultimate theoretical value of 29.4%. , Moreover, the comparably high operation stability of crystalline Si solar cells could practically meet the needs of sustainable electronic power and therefore dominated the renewable-energy market in the past decade.…”

Vanadium pentoxide (V2O5) has been proposed as a promising selective contact for holes in organic electronic devices. In this study, the strategy was undertaken for minimizing the possible charge recombination at electrode surfaces in the silicon-based hybrid solar cells and further allowed the exceptional capability for hole extraction. This was accomplished by inserting the mixed vanadium oxide (VO x ) phases based on a simplified low-temperature fabrication process. Detailed examinations of crystallinity, chemical states and compositions, topography, and optical transmittance of such VO x layer were performed, revealing the coexistence of V2O3 and V2O5 phases that facilitated the hole-selective contact due to establishing the ohmic-like interfaces as well as blocking the transport of electrons, and the optimal anneal treatment at 200 °C was further validated. On the basis of this, the insertion of a VO x electron-blocking layer in the integrated organic/inorganic hybrid solar cells was fully fabricated with solution processing methods, presenting the leading conversion efficiency of 14.4% being approximately 1.6 times superior than the conventional VO x -free hybrid solar cells. These results provided a viable rule toward realizing the high-performance and low-cost solar cells and might further offer the high potential for other functional applications based on hybrid material designs.
