摘要：

Antimony sulfide (Sb2S3) is an impressive absorber material for indoor photovoltaics and the bandgap of 1.7 eV can well match with the emission spectra of the white light-emitting diode (LED). Herein, the high quality Sb2S3 films with uniform S distribution, high S content, low Sb-O content and [hk1] preferential orientation can be successfully prepared by the supplemental adding Na2S2O3 strategy during the chemical bath deposition process. The Sb2S3 solar cells show the power conversion efficiency (PCE) of 7.73 % using the solar simulator (Air mass number 1.5, 100 mW & sdot;cm-2) and 18.16 % using the warm white LED with color temperature of 3347 K and illuminance of 1000 lux. The PCE of 18.16 % is the highest value of Sb2S3 indoor photovoltaics and the result demonstrates that the supplemental adding Na2S2O3 strategy during the chemical bath deposition process is an efficient path to prepare uniform S distribution Sb2S3 films.
