Fourth Generation Solar Cells: A Review

Among the multifarious kinds of small molecular photovoltaic materials, squaraines are quite attractive due to their facile and low-cost synthesis, intense and broad absorption in Vis-NIR spectral regions with very high molar extinction coefficients. Nevertheless, one key factor limiting the performance of squaraine-based organic solar cells (OSCs) is their low fill factor (FF), which is ascribed to the low hole mobility of the active layer. Here, we successfully reported a large π-extended bis(squaraine) electron donor, namely D-BDT-SQ, that showed one order of magnitude enhanced hole mobility in the donor–acceptor composite film, up to 10−4 cm2 V−1 s−1. As a result, an impressive power conversion efficiency (PCE) of 7.41% with a high FF of 0.60 was achieved for solution-processed bulk heterojunction OSCs when the working temperature of devices was 80 °C, which is, to the best of our knowledge, the record PCE among those reported for squaraine-based single-junction OSCs.

An effective π-extended squaraine for solution-processed organic solar cells with high efficiency

Since its discovery in 1839, research on the synthesis and application of perovskite materials has multiplied largely due to their suitability to be used in the fields of nanotechnology, chemistry and material science. Appropriate changes in composition or addition of other elements or blending with polymers may result in new hybrid and/or composite perovskite materials that will be applied in advanced fields. In this review, we have recapitulated the recent progress on perovskite nanomaterial in solar cell, battery, fuel cell and supercapacitor applications, and the prominence properties of perovskite materials, such as excellent electronic, physical, chemical and optical properties. We discussed in detail the synthesis and results of various perovskite hybrid nanomaterials published elsewhere. We have also discussed the results of various studies on these low dimensional composite nanomaterials in broad sectors such as electronics/optoelectronics, batteries, supercapacitors, solar cells and electrochemical sensors.

The effect of incorporation of plasmonicgold (Au) nanoparticle at the interface between trans-parent front electrode and hole transporting layer ofmolybdenum trioxide is studied using bulk hetero-junction organic photovoltaic cells (OPVs) of poly-3-hexylthiophene and phenyl-C 61 -butyric acid methyl es-ter (P3HT:PC 61 BM) fabricated in ambient air conditionas a model system. The current-voltage measurement ofITO/MoO 3 /P3HT:PC 61 BM/Al and Au incorporated OPVsunder AM1.5G light of intensity 1 Sun showed 16% in-crease in short circuit current density (J SC ) and a 25%improvement in power conversion efficiency (PCE) withtheincorporationofAunanoparticles.Theexternalquan-tumefficiency(EQE)measurementshowedvaluesvaryingfrom 40% to 60% over a wavelength range 350 nm to700nmwithEQEenhancementoverabroadspectralwin-dow.ScanningelectronmicroscopestudieswereusedtostudythemorphologyoftheAunanoparticlesmade.

Enhancement in Photovoltaic Properties of Plasmonic Nanostructures Incorporated Organic Solar Cells Processed in Air Using P3HT:PCBM as a Model Active Layer

Inverted bulk heterojunction solar cells based on low temperature solution processed squaraine (SQ) and [6,6]-phenyl C71 butyric acid methyl-ester (PC71BM) with varying blend ratios were made in air. An optimized bulk heterojunction device of SQ and PC71BM (with a blend ratio of 1 : 6) showed a power conversion efficiency (PCE) of 2.45% with an incident photon to current conversion efficiency of 65% at 680 nm and a spectral window extending to the NIR region. The devices also showed an enhanced PCE value of 4.12% upon continuous illumination from an AM1.5G light source of intensity 1 Sun. The intensity dependent photocurrent studies showed a monomolecular recombination mechanism in the photovoltaic device performance. The device stored in air showed reasonable stability for a period of one month.

Squaraine based solution processed inverted bulk heterojunction solar cells processed in air

Low-dimensional (LD) perovskite materials possess unique physical and optical properties, which makes them promising candidates for optoelectronic and photovoltaic applications. Compared to their three-dimensional counterpart, the optical and electrical properties of the LD perovskites can be tuned by controlling their structure and size. Here, we discuss the structural and physical properties along with different types of the synthesis method of the LD perovskites. We also demonstrate the different applications of the LD perovskite material in optoelectronic and photovoltaic devices.
