The thermal regulation of a silicon photovoltaic (PV) solar system is essential as the module surface temperature beyond 25 °C deteriorates its Power Conversion Efficiency (PCE). intensity radiation seems to have crucial impact on PCE PV system. present study aims assess effect variations PCEs modules integrated with and without passive cooling systems. used systems are (a) multi-pipe copper fr...

Abstract From ∼1500 published journal papers on organic photovoltaics (OPVs), we extracted the OPV performance parameters of power conversion efficiency (PCE), open-circuit voltage ( V OC ) and short-circuit current density J SC chemical structures photovoltaic layer materials to investigate relation between data OPVs accompanied by non-fullerene acceptors (NFAs). Our analysis indicates that th...

Abstract Organic perovskite solar cells (PSCs) is concerned due to their photoelectric performance, low price, and solution treatable. However, there are defects in crystals that affect the power conversion efficiency (PCE) improvement. These effects include carrier transport, morphology of film surface, etc. Passivation a reliable reduce crystals. We doped 2-mercaptoimidazole (2-MI) active lay...

Semitransparent organic solar cells (ST-OSCs) are promising candidates for applications in building-integrated photovoltaics (BIPV) as windows and facades. The challenge to achieve highly efficient ST-OSCs is the trade-off between power conversion efficiency (PCE) average visible transmittance (AVT). Herein, solution-processed demonstrated on basis a polymer donor, PM6, small molecule acceptor,...

Polymer bulk heterojunction (BHJ) solar cells consisting of the photoactive layer containing the interpenetrating network of electron donating polymer and electron accepting PC71BM has been proved to be quite effective in converting the solar energy into electrical energy. After many efforts, the power conversion efficiency (PCE) of the polymer solar cells (PSCs) was improved up to 9.2%. Unfort...

In this work, we have demonstrated the results of several positive effects that arise from the addition of graphene quantum dots (GQDs) to solution-processed small molecule bulk-heterojunction (SM-BHJ) solar cells fabricated from a p-DTS(FBTTh(2))(2)/[6,6]-phenyl C(71) butyric acid methyl-ester (PC(71)BM). The device with an optimized ratio of GQDs exhibits increased current density and fill fa...

In this report, plasmonic effects in organic photovoltaic cells (OPVs) are systematically analyzed using size-controlled silver nanoparticles (AgNPs, diameter: 10 , 100 nm), which were incorporated into the anodic buffer layer, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS). The optical properties of AgNPs tuned by size considerably influence the performance levels of devic...

Enhanced performance of polymer solar cells (PSCs) based on the blend of poly[N-9''-hepta-decanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (PCDTBT):[6,6]-phenyl-C70-butyric acid methyl ester (PC71BM) is demonstrated by titanium dioxide (TiO2) interface modification via CuInS2/ZnS quantum dots (CZdots). Devices with a TiO2/CZdots composite buffer layer exhibit both a...
