The construction of PV solar cells uses a number of critical elements. One is indium an ingredient of the transparent conducting coating on the surface of the cell. The average material intensity for indium in solar cells is approximately 0.05 kg/kWnom. Calculate the quantity of indium that would be required for a project that would provide PV solar power with capacity factor of 0.25, sufficient to meet one third of the present needs of the US, population 301 million, each using an average of 10.2 kW. The current world production of Indium is 600 tones per year. If the solar project were to be implemented over a 5 year time span, is it true that the supply of indium be adequate?

The student engineer of a campus radio station wishes to verify the effectiveness of the lightning rod on the antenna mast (see the figure below). The unknown resistance Ry is between points C and E. Point E is a "true ground," but is inaccessible for direct measurement because the stratum in which it is located is several meters below Earth's surface. Two identical rods are driven into the ground at A and B, introducing an unknown resistance Ry. The procedure for finding the unknown resistance Ry is as follows. Measure resistance R, between points A and B. Then connect A and B with a heavy conducting wire and measure resistance R2 between points A and C.

Answer the following True or False: 1. A direct bandgap material absorbs more light in a given thickness than an indirect band gap material. 2. CdTe thin film solar cells make up less than 8% of the current installed photovoltaic capacity. 3. The voltage generated in a photovoltaic cell is linearly dependent on the light intensity. 4. All commercially produced photovoltaic cells use a transparent conducting oxide (TCO) as a front contact. 5. Si solar cells are used in space applications due to their higher resistance to radiation damage.
