Copper nanoparticle inks have drawn much attention since they have the potential to constitute an alternative cost‐effective solution than other noble metals nanoparticle inks such as Ag for indium tin oxide (ITO)‐free printed electronic applications. Our research and development efforts have produced high conductivity copper nanoparticle inks which have excellent jetting and printing properties resulting in high quality inkjet‐printed (IJP) Cu nanoparticle‐based metal grids. We present ITO‐free, Si‐PCPDTBT: PC[70]BM organic photovoltaics (OPVs) processed in ambient low‐cost fabrication conditions comprising for the first time embedded and non embedded inkjet‐printed copper grid/Poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) as the bottom electrode with power conversion efficiencies (PCE) of 2.56 and 3.35%, respectively. The results of the ITO‐free OPVs using inkjet‐printed Cu nanoparticle current collecting grids are discussed relevant to reference ITO‐based OPVs with PCE of 4.92%.

“…The reference device (device A) shows a V oc of 0.60 V, a J sc of 10.09 mA cm −2 , a FF of 58.2%, and a PCE of 3.60% (average value), which is comparable to the reported values of the inverted BHJ-PSC devices fabricated under similar conditions ( o -dichlorobenzene as solvent). [36][37][38] Upon bulk g-C 3 N 4 doping (device B), the PCE shows a negligible change from 3.60% to 3.58% with quite comparable photovoltaic parameters (see Table 1 , ≈13.4% enhancement) is primarily responsible for the PCE enhancement of ≈17.5% relative to that of the reference device (see Figure S4, Supporting Information), while V oc and FF exhibit only negligible increases. For the cases of doping carbon and CdS QDs in [N-9″-hepta-decanyl-2,7-carbazolealt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-ben-zothiadiazole)] (PCDTBT):PC 71 BM and P3HT:PC 61 BM, respectively, obvious PCE enhancements were observed as well, which resulted from the increase of both J sc and FF.…”

.36%, and 9.18%, which are enhanced by ≈17.5%, 11.6%, and 11.8%, respectively, compared to that of the reference (undoped) devices. The PCE enhancement of the C 3 N 4 QDs doped BHJ-PSC device is found to be primarily attributed to the increase of short-circuit current ( J sc ), and this is confi rmed by external quantum effi ciency (EQE) measurements. The effects of C 3 N 4 QDs on the surface morphology, optical absorption and photoluminescence (PL) properties of the active layer fi lm as well as the charge transport property of the device are investigated, revealing that the effi ciency enhancement of the BHJ-PSC devices upon C 3 N 4 QDs doping is due to the conjunct effects including the improved interfacial contact between the active layer and the hole transport layer due to the increase of the roughness of the active layer fi lm, the facilitated photoinduced electron transfer from the conducting polymer donor to fullerene acceptor, the improved conductivity of the active layer, and the improved charge (hole and electron) transport.

“…While the use of PEDOT:PSS in conventional architecture is straightforward, there are challenges in spin‐coating PEDOT:PSS, which is a water‐based solution, on top of the active layer which is typically hydrophobic. This can be improved by the use of additives, but the stability of the devices is strongly dependent on the additive used . Solution processed metal oxide layers, such as WO 3 , have been proposed as a replacement for PEDOT:PSS.…”

Polymer, perovskite, and dye‐sensitized solar cells (DSSCs) are promising technologies for next generation low cost photovoltaic cells. Among these, perovskite solar cells are the newest technology and have the highest efficiency, while DSSCs are closest to commercialization with several companies producing the DSSC materials and modules and existing DSSC installations. However, all three types of solar cells share a concern about lifetime and stability. For each type of devices, there are specific concerns and degradation mechanisms, and all of the devices require encapsulation and exhibit varying degrees of sensitivity to moisture, oxygen, elevated temperature and UV illumination depending on the device structure and materials used. We are discussing the stability and lifetime for each type of cells and future outlook of these technologies. (© 2016 WILEY‐VCH Verlag GmbH &Co. KGaA, Weinheim)
