It has been known that the structure of bulk-heterojunction solar cell is more effective in comparison to that of planar structure regarding to the large interface layer between acceptor and donor (P3HT and PCBM) which further facilitate the process of recombination and dissociation of charges.
The mechanism of charge generation was investigated in the solar cell structure regarding to the effect of LSPR from AuOA.
Fabrication of solar cell in the structure of ITO/ZnO/P3HT:PCBM:AuOA/PEDOT:PSS/Ag was done by use of spin coating technique.
Absorbance spectra of hybrid solar cell structure incorporated AuOA.

LDHs present analogous structures of piroaurita-sjögrenita minerals, with a crystalline structure being derivative from brucite, Mg(OH)2.
Above 550oC, the colapse of the structures occurred due to their complete dehydroxylation [34, 35].

The preparation, structure and photoluminescence (PL) properties of the SnO2 films were
investigated.
All the obtained films were polycrystalline with the rutile structure.
Comparing with GaN [9] and ZnO [10], SnO2 as a promising violet and blue material has some dominance such as a wider band gap (3.6 eV), lower deposition temperature and more physical chemistry stability.
In the present paper, the structure and photoluminescence properties of SnO2 films prepared by APCVD were investigated.
The results of XRD, AFM reveal that the SnO2 films is rutile-type structure, the grain size is about 1000 nm.

The morphology and crystal structure of the EG/ZnO composites have been characterized by the means of SEM and XRD.
The results are shown as follows: the EG/ZnO composites keep the laminated and microporous network structure of EG.
The crystal structure of the composites is also determined by X-ray powder diffractometer (XRD) of D/MAX-rB, which is radiated by Cu Kα.
The results indicate the prepared EG/ZnO composites are the combination of ZnO particles and EG, and have maintained their structure features concurrently.
The above results show that the EG/ZnO composites keep both crystal structure of ZnO particles and EG, which is consistent with the analytic results of SEM.

It is called "dot structure" pyrocarbon and its formation
mechanism is simple proposed.
It is called "dot structure" for the moment.
The dot structure has a lot of irregular carbon form and other element is not found except carbon by EDS.
At 950 °C, it is assumed that the process is strongly diffusion limited by depletion effect which led to a lower density and influenced the chemistry of carbon formation [6].
In addition, it is noticeable that dot structure possesses a high g and crystallite size at 30.5 nm.

The influence of different heating and sterilization methods on the chemical and physical structure of biopolymer thin films composed of chitosan and carboxymethylcellulose was evaluated.
This reaction leads to the formation of melanoidin structures (containing C=N bonds) in a cross-linking interchain reaction process [12, 13].
This annealing effect results in a denser packing film structure when films are re-cooled to room temperature [17].
