27:T451,Short energy intensive hydrothermal liquefaction (HTL) of biomass in the presence of Ni salt catalyst selectively generates H₂ in the product gas and biocrude mainly containing C₁-C₃ acids (formic, lactic, propionic, acetic), HMF and furfural. The H₂ mass balance indicated that only 3.12 vol% H₂ in biomass (cotton) was released as product gas; 48.7 vol% was captured in the C₁-C₃ acids while the remainder H₂ was trapped in oxygenated compounds and char. Continuing HTL after 120 minutes caused no further increase in gas phase H₂ yields. To enhance the H₂ yields with minimal energy input, solar photocatalytic reforming (PR) of the biocrude with Pt/TiO₂ catalyst was investigated. Photocatalysis of activated carbon (AC) treated biocrude generated an additional H₂, 17.82 wt%. H₂ yields from photoreforming of simulated biocrude acid mixture and actual biocrude were compared. Enhanced H₂ generation was observed with integrated HTL-PR of biomass.28:T4dd,The optics of organic-inorganic halide perovskites materials in thin-film smooth surface p-i-n solar cell has been studied. The study was conducted for CH3NH3PbI3 perovskite material, used as a photoactive layer and sandwiched between ultrathin electron transport layer of TiO2 and hole transport layer of P3HT. The investigation was carried out based on the optical wave propagation simulation results of quantum efficiency and short circuit current. A reference model of solar cell exhibits a maximum of 21.79 mA/cm2 short circuit current as well as 76% of external quantum efficiency (EQE) for 620 nm to 700 nm of spectral range of wavelengths. Analyzing the influence of thickness for each layer on the short circuit current and the quantum efficiency the cell was optimized. Finally, a comparative analysis has also been done between CH3NH3PbI3 and CH3NH3PbI2Cl perovskite thin-film solar cell, where CH3NH3PbI2Cl based solar cell gives 2.7% higher short circuit current and around 7.5% higher photon absorption, particularly in the near infrared red regions of spectrum (700 nm- 800 nm) and for the 360 nm of absorbing layer. Throughout the research, a Finite Difference Time Domain (FDTD) based Maxwell’s curl equations solver was used.
