SULFUR DIFFUSION IN POLYCRYSTALLINE THIN-FILM CdTe SOLAR CELLS
X-ray diffraction and photoluminescence measurements have been used to characterize the diffusion of S into CdTe during post growth annealing of CdTe solar cells. For anneals at 410°C in the presence of CdCl2, evidence that both a CdTe1-xSx phase and nearly-pure CdTe are present near the back contact is observed. The ternary phase becomes more prominent and the S concentration increases with de...
متن کاملGrain boundaries in CdTe thin film solar cells: a review
The current state of knowledge on the impact of grain boundaries in CdTe solar cells is reviewed with emphasis being placed on working cell structures. The role of the chemical composition of grain boundaries as well as growth processes are discussed, along with characterisation techniques such as electron beam induced current and cathodoluminescence, which are capable of extracting information...
متن کاملPolymer solar cells with enhanced open-circuit voltage and efficiency
Following the development of the bulk heterojunction1 structure, recent years have seen a dramatic improvement in the efficiency of polymer solar cells. Maximizing the open-circuit voltage in a low-bandgap polymer is one of the critical factors towards enabling high-efficiency solar cells. Study of the relation between open-circuit voltage and the energy levels of the donor/acceptor2 in bulk he...
متن کاملMonocrystalline CdTe solar cell with ultra-high open-circuit voltage and substantially increased efficiency
We report the demonstration of CdTe/MgxCd1-xTe double heterostructures (DHs) with a carrier lifetime of 3.6 μs and an interface recommendation velocity of 1.2 cm/s, comparable to or even better than the best values reported for GaAs/Al0.5Ga0.5As (18 cm/s) and GaAs/Ga0.5In0.5P (1.5 cm/s) DHs. Combined with a p-contact layer (8 nm a-SiCy:H + 4 nm a-Si:H), devices consisting of MgxCd1-xTe/CdTe/Mg0...
متن کاملOpen-Circuit Voltage Physics in Amorphous Silicon Solar Cells
We have performed computer calculations to explore effects of the p/i interface on the opencircuit voltage in a-Si:H based pin solar cells. The principal conclusions are that interface limitation can occur for values of VOC significantly below the built-in potential VBI of a cell, and that the effects can be understood in terms of thermionic emission of electrons from the intrinsic layer into t...
