Paper Abstract

In order to fabricate high efficiency indium tin oxide/InP solar cells, the aspects of electrical contacts and antireflection coatings must be carefully addressed. It has been determined that low resistance electrical contact can be made to p- InP by using a AuBe alloy and properly sintering. Additionally, low resistance, stable and adherent grid contacts can be made to indium tin oxide with the use of Cr/Pd/Au metallization. With proper design, the total power losses of these grid contacts can be limited to about 3.0%. Finally, the design and effects of a double layer antireflection coating using indium tin oxide and magnesium fluoride are discussed indicating that this aspect of cell design still contains several opportunities for improvement.
