Figure 15.
The graph displays the efficiency percentages of cadmium sulfide, C d S, and zinc sulfide, Z n S, as functions of temperature, ranging from 280 degrees Celsius to 380 degrees Celsius. The vertical axis represents efficiency, labelled as a percentage, with values ranging from 2 to 12 percent. The horizontal axis indicates temperature with increments of 20 degrees. Two separate curves are plotted, one for C d S shown with a black dashed line and the other for Z n S represented by a red dashed line, both displaying distinct trends in efficiency. An annotation points to a specific data point labelled C Z T S as deposit. The graph displays a notable drop in efficiency as temperature increases for both materials, with specific efficiency values marked along the curves.Solar cell efficiency variation with temperatures for two different buffer layers
