AbstractMorphologically controllable thin-films of a zinc-containing tetraphenylporphyrin (ZnTPP) combined with an L-glutamide lipid has been fabricated and complexation of ZnTPP with fullerene was examined for organic thin-film solar cells, which gave 3 times enhancement of solar energy-to-electricity conversion efficiency through chlorobenzene-annealing in comparison with the conversion efficiency of untreated one.

To reveal the effects of annealing condition on CZTSSe thin film solar cells, co-sputtering and subsequent selenization were used to prepare CZTSSe thin films. Structural, morphological and optical properties of CZTSSe thin films were investigated. CZTSSe thin films with various Se/(S+Se) ratio ranging from 0.69-0.78 were obtained. Representative peaks corresponding to CZTSSe in XRD and Raman results showed a slight shift to lower diffraction angle and wavenumbers. Selenization time significantly influenced the morphologies of CZTSSe films and the gradual grown up grain size was observed. VOCdeficit values down to 839 mV was achieved for the best cell. CZTSSe solar cell with the selenization time of 10 min showed a best conversion efficiency of 5.32%, which presented a 50% enhancement comparing to the solar cells with insufficient and over-selenized absorbers.
