Q: A single-crystal solar cell is made from the semiconductor, silicon.  Even though 99.999% pure, a silicon wafer is useless for solar-PV conversion until it is properly “doped” and made into a solar cell.  The top side of the solar cell (facing toward the sun) has been doped with ____________________________, making its surface-polarity ________________________.

Q: A single-crystal solar cell is made from the semiconductor, silicon.  Even though 99.999% pure, a silicon wafer is useless for solar-PV conversion until it is properly “doped” and made into a solar cell.  The bottom side of the solar cell (facing away from the sun) has been doped with ____________________________, making its surface-polarity _______________________.

Q: Aside from the single-crystal, silicon solar cell technology, there are several other styles of solar cell in use today.  Name one of these: ___________________________________________.

Q: Look at the graph below.  This illustrates normal operating characteristics of a solar cell, a PV module, or a PV array.

This graph is typically referred to as the _________  ________________ of a solar cell, a PV module, or a PV array.

Q: Look at the graph below.  Assume this graph is describing the operating characteristics of an individual solar cell.

Point “A” is referred to as the   ____________________ of the solar cell; and, point “B” is referred to as the _________________________ of the solar cell.

Q: Look at the graph below.  Assume this graph is describing the operating characteristics of an individual solar cell.

Point “C” is referred to as the   ____________________ of the solar cell; and, point “D” is referred to as the _________________________ of the solar cell.

Q: Look at the graph below.  Assume this graph is describing the operating characteristics of an individual solar cell.

Point “E” is referred to as the   ____________________ of the solar cell.

Q: The specifications printed on the name plates of most modern PV modules are given in “STC.”  “STC” stands for _______________________  _____________  ______________________, and is qualified as: _______________W/m^2; _______C^o; and, ____________A.M.

Q: As the irradiance on a PV module increases, the primary impact will be that its ________________ will go ________________.
