Alternative photo-sintering techniques for thermal annealing processes are used to improve the morphology, layer properties, and enhance solar cell performance. The fast, nontoxic, low cost, and environmentally friendly characteristics of Cu2ZnSnS4 have led to its consideration as an alternative potential absorber layer in copper indium gallium diselenide thin film solar cells. This work investigates the photo-sintering process for the absorber layer of Cu2ZnSnS4 solar cells. A Cu2ZnSnS4 layer was grown by hot-injection and screen-printing techniques, and the characteristics of the photo-sintered Cu2ZnSnS4 layer were evaluated by X-ray Diffraction, Raman spectroscopy, Energy dispersive X-ray analysis, Ultraviolet-visible spectroscopy, and field emission scanning electron microscopes. Overall, the optimal composition was Cu-poor and Zn-rich, without a secondary phase, estimated optical band-gap energy of approximately 1.6 eV, and enhanced morphology and kesterite crystallization. Using an intensity pulse light technique to the CZTS layer, fabrication of the solar cell device demonstrated successfully, and the efficiency of 1.01% was achieved at 2.96 J/cm2.

“…A reliable and renewable energy source, solar energy is accounted as a future energy resource due to its abundance and completely free of cost from sunlight. A low-cost wide band gap semiconducting oxide based solar cell, named dye sensitized solar cell (DSSC) is considered as potential alternative in the field of photovoltaic devices due to its high power conversion efficiency (PCE) and ease of manufacturing [6][7][8][9]. Till now, Gratzel group reported so far highest PCE of 12.3% using DSSCs with nanoporous TiO 2 photoanode [10].…”

The proposed work reports that ZnO nanoflowers were grown on fluorine-doped tin oxide (FTO) substrates via a solution process at low temperature. The high purity and well-crystalline behavior of ZnO nanoflowers were established by X-ray diffraction. The morphological characteristics of ZnO nanoflowers were clearly revealed that the grown flower structures were in high density with 3D floral structure comprising of small rods assembled as petals. Using UV absorption and Raman spectroscopy, the optical and structural properties of the ZnO nanoflowers were studied. The photoelectrochemical properties of the ZnO nanoflowers were studied by utilizing as a photoanode for the manufacture of dye-sensitized solar cells (DSSCs). The fabricated DSSC with ZnO nanoflowers photoanode attained reasonable overall conversion efficiency of~1.40% and a short-circuit current density (J SC ) of~4.22 mA cm −2 with an open circuit voltage (V OC ) of 0.615 V and a fill factor (FF) of~0.54. ZnO nanostructures have given rise to possible utilization as an inexpensive and efficient photoanode materials for DSSCs.Crystals 2019, 9, 405 2 of 13 of recombination rate and efficient electron transport in the photoanode [15]. Most the reported DSSCs based on ZnO photoanodes are inferior to DSSCs based on the TiO 2 photoanode [16][17][18], which normally can be attributed to ZnO dissolution to Zn 2+ via the adsorbed acidic dye such as N3, N719, and black dye, resulting in the aggregate formation of Zn 2+ and dye molecules [19]. These aggregates formation of Zn 2+ /dye complexes are further blocked the injected electrons from the photoexcited dye molecules to the ZnO, which results in decrease in proper electron injection. It is realized that some extent of research on the improvement in performance of ZnO-based DSSC are needed to outperform the aggregates formation of Zn 2+ /dye complexes [19].ZnO is highly scrutinized n-type semiconducting oxide owing to its an unique wide band gap of 3.37 eV and considerable large exciton binding energy of~60 meV at ambient condition [20,21]. The unique properties of ZnO materials have attracted attention in the area of electrochemical and photoelectrochemical devices because they have special ability to grow a variety of different nanostructures [22][23][24][25][26][27][28][29]. Apart from thermal growth of ZnO, ZnO synthesis at low temperature solution processes has recently been popularized due to ease of processibility, high aspect growth ratio, low-cost, and high yield [30]. In past few years, researches are experimented to elevate the conversion efficiency of ZnO-based DSSCs by adopting different structural and morphological aspects like 1D, 2D, and 3D branched networks and mixed morphologies for preparing ZnO photoanodes [31][32][33]. Several works on the utilization of 1D and 2D ZnO-based photoanodes have already been reported, but the conversion efficiencies of DSSCs are not competent to TiO 2 based DSSCs [29][30][31][32][33].Herein, we report the low-temperature hydrothermal synthesis, characterization...
