Abstract
THE PROPOSED PROGRAM RELATES TO THE FIRST USE OF TETRAAZAANNULENES AS PHOTOSENSITIZERS FOR PHOTOELECTRO- CHEMICAL CELLS. A NEW MATERIAL IS DESCRIBED FOR FORMING PHOTOSENSITIZED SEMICONDUCTORS WITH EXTENDED LIFE AND IMPROVED EFFICIENCY. THE AVAILABILITY OF AN IMPROVED EFFICIENCY AND RELIABILITY SOALR CELL WILL PROVIDE NASA WITHWITH AN ALTERNATIVE HIGH TECHNOLOGY POWER SOURCE. THE MAJOROBJECTIVE OF THE PROGRAM IS TO FORM MONOMOLECULAR FILMS BY SUBLIMATION OF TAAS ON TWO TYPES OF SEMICONDUCTORS AND TO TEST THEIR PHOTORESPONSE AND QUANTUM EFFICIENCY IN CELL AND STACKED CELL CONFIGURATIONS. SECONDARY OBJECTIVES INCLUDE GAINING A BETTER UNDERSTANDING OF THE ROLE OF THE PIE-BOND SYSTEM OF ORGANIC MACROCYCLES IN IMPROVING QUANTUM YEILD OF SEMICONDUCTORS. THE PROGRAM APPROACH IS TO COAT SNO2 ANDSRTIO3 ELECTRODES WITH TAAS AND MEASURE THE PERFORMANCE OF SUCH ELECTRODES IN FE+2/FE+3 ACID ELECTROLYTES. OPTIMIZED ELECTORDES WILL BE TESTED IN A SOLAR BATTERY.
