Nano-structured CdTe, CdS and TiO2 for thin film solar cell applications

A green and facile hydrothermal approach for the synthesis of high-quality semi-conducting Sb2S3 thin films

“…The nanocrystal thin films of metal sulfide (e.g., PbS [1], CdS [2], CdSe [3], CdTe [4], Sb2S3 [5], etc.) have been widely utilized as the absorber layer materials for solar cells [6].…”

Enhancing performance of inverted polymer solar cells using two-growth ZnO nanorods

“…Moreover, ZnO nanorod structure promotes valid area of the junction between ZnO and organic light absorbers. Hence, the efficiency of electron-collection, transportation, and suppression of the leakage current would be improved [22][23][24][25][26][27].…”

Nitrogen Incorporation of Nanostructured Amorphous Carbon Thin Films by Aerosol-Assisted Chemical Vapor Deposition

“…The clear and flawless particle results from the high kinetic energy gained by the particles, which makes it easier for the particles to migrate on to the surface and easier for them to grow [17]. For the a-C solar cell application, the nanostructured material has some promising advantages, such as that the optical absorption path is much larger [7], and the absorber layer is thin, thus the light generated electrons and holes will only have to travel over much shorter path and thus the recombination losses are greatly reduced [18], and the energy band can be tailored by varying the size of nanoparticles, thus more designs of the absorber layers in the solar cell can be done [7]. Other than that, the successful doping condition for the nitrogen doping is confirmed through the FESEM spectrum results, with the presence of the nitrogen (N) element in the a-C: N sample.…”

“…The a-C material, having the amorphous nature is very hard to obtain in a nano-structured form, however the application of AACVD is expected to cope with the problems. In the case of using the a-C in a solar cell application, nano-structured a-C has many advantages, such as the optical absorption path being much larger [7], the absorber layer baing thin, thus the light generated electrons and holes will only have to travel over a much shorter path and thus the recombination losses are greatly reduced [8] and the energy band can be tailored by varying the size of nanoparticles, thus more designs of the absorber layers in the solar cell can be done [7].…”
