摘要： A quantum efficiency test controller (QETC) and related techniques for measuring quantum efficiency are described. The QETC performs one or more test iterations to obtain test results regarding quantum efficiency of a multijunction photovoltaic device (MPD) having a number N of photovoltaic junctions (N>0), where the QETC is associated with N bias light sources. During a test iteration, the QETC activates a grating monochromator to emit a first test probe of monochromatic light at a first wavelength; and while the grating monochromator is emitting the first test probe, iterates through and activates each of the N bias light sources to emit a corresponding bias band of wavelengths of light. After performing the test iteration(s), the QETC generates an output that is based on the test results related to the quantum efficiency of the MPD.

摘要： Provided are methods and systems for treating shunts on solar cell substrates. Also provided are solar cells including such substrates. A shunt detected on a substrate proximate to a metallized grid pattern is electrically disconnected from at least the bus portion of the grid, which reduces shunt's impact on performance on the solar cell. An antireflective layer may be disposed between the shunt and a portion of the grid extending over the shunt. The exposure pattern of a photoresist used to form the antireflective layer may be adjusted accordingly to achieve this result. In some embodiments, the metallized grid may be modified by adjusting the exposure pattern of a photoresist used to form this grid. The grid may be modified to avoid any contact between the grid and the shunt or to disconnect a portion of the grid contacting the shunt from the bus portion area of the grid.
