Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...
