OSTI ID:6030791
This program is examining a promising new spray pyrolysis technique to deposit thin films of CuInSe/sub 2/ for terrestrial solar cell applications. This technique is very attractive for depositing high quality thin film CuInSe/sub 2/ solar cells due to its inherent simplicity and potential low cost. The initial period has focused on studying the basic solution chemistry needed to deposit CuInSe/sub 2/ by this new method. To date, significant progress has been achieved in the areas of spray solution stability and process chemistry. This progress has enabled us to successfully spray deposit high purity thin films of p-type CuInSe/sub 2/ which have low resistivity without post deposition annealing. Preliminary Schottkey barrier and heterojunction devices have been fabricated which showed encouraging photovoltaic behavior. Now that the problems in the chemistry of the spray process have been solved, the next period will focus on improving the material properties of the films and examining solar cell device characteristics.
