摘要:
A method of producing polycrystalline CdTe materials and devices that incorporate the polycrystalline CdTe materials are provided. In particular, a method of producing polycrystalline p-doped CdTe thin films for use in CdTe solar cells in which the CdTe thin films possess enhanced acceptor densities and minority carrier lifetimes, resulting in enhanced efficiency of the solar cells containing the CdTe material are provided.

摘要:
A diagnostic device (40) having layers (25, 27, 29) corresponding to respective layers (24, 26, 28) of a given photovoltaic module (20). The diagnostic device is provided for testing and monitoring a condition of the given photovoltaic module. The layers of the diagnostic device may be made of respective materials with the same or substantially the same electrical resistance and aging characteristics as the respective layers of the given photovoltaic module under operational conditions. Electrodes (42, 44, 50A-C, 52A-C, 54A-C) of the diagnostic device are configured to independently measure electrical resistance along at least two different current resistance paths in the diagnostic device corresponding to respectively different current leakage paths (R1, R′1, R2-4, R5, R5) of the given photovoltaic module.
