Abstract In this paper, we focus on the study of the effects of the work function of  PEDOT: PSS on the hybrid photovoltaic cells based on silicon /PEDOT:PSS, mainly  in  the following aspects of the work:

(1)clean surface of silicon wafer,The cut silicon wafers were placed in acetone, ethanol and de ionized water with ultrasonic  cleaning  machine  for 15 minutes。,And   then

washed with deionized water,Dry nitrogen gun, and then into the volume ratio of 3:1 in a mixture of sulfuric acid and hydrogen peroxide solution, when heated to 115 ℃  more than 1 hours, wait for after natural cooling, using deionized water rinse, blow dry   nitrogen

gun。

(2)To clean the n-type Si by two-step method to/methyl chloride surface passivation of methylation。。

(3)Prepare based on Si/PEDOT: PSS hybrid solar cells, under different annealing conditions of PEDOT: PSS films for annealing treatment, the annealing environment of PEDOT: PSS films performance impact, and finally the PEDOT: PSS films of  the influence of work function on the device performance。 The results show that the annealing environment change can improve PEDOT: PSS film conductivity and work function,  so that the device of photoelectric conversion efficiency was improved。

(4)AFORS - HET solar battery simulation software was used to simulate the metal work function of the increasing impact on battery performance, the results show that the metal work function improvement can improve the performance of the device, and the experimental results are identical with each other。

Keywords: the work function of PEDOT: PSS,Photoelectric conversion efficiency,Electric conductivity
