TLDR
In this paper, strong evidence for an illumination-induced change in minority charge carrier diffusion length is given for Cu(In,Ga)Se 2 solar cells, which can be attributed to an increase in doping density causing a reduced space charge region width as verified by capacitance-voltage profiling.About:

Large metastability in Cu (In,Ga)Se2 devices: The importance of buffer properties
Ingrid Repins,Stephen Glynn,Timothy J. Silverman,Rebekah L. Garris,Karen Bowers,Bart Stevens,Lorelle M. Mansfield +6 more
TL;DR: This study attempts to reproduce large metastabilities like those in some commercial products both through absorber and buffer processing variations in small devices and confirms that buffer effects alone are sufficient to explain the large metastability seen in these devices.
Journal ArticleDOI
Luminescence Analysis of Charge-Carrier Separation and Internal Series-Resistance Losses in Cu (In ,Ga )Se 2 Solar Cells
TL;DR: The investigation shows that residual luminescence is a generic consequence of the finite coupling strength between the electron-hole system inside the photovoltaic absorber and the external electrical circuit.

Modelling polycrystalline semiconductor solar cells
TL;DR: In this paper, an overview is given of various electronic effects present in polycrystalline thin film solar cells, which do not occur in standard crystalline Si solar cells and how these effects are treated numerically in a numerical solar cell simulation tool, SCAPS.

Depletion-Layer Photoeffects in Semiconductors
TL;DR: The theory of photoconduction through the reverse-biased $p\ensuremath{-n$ junction in semiconductors is developed without the customary assumption that carrier generation in the junction depletion layer is negligible as discussed by the authors.

Determination of defect distributions from admittance measurements and application to Cu(In,Ga)Se2 based heterojunctions
TL;DR: In this article, a method to deduce energy distributions of defects in the band gap of a semiconductor by measuring the complex admittance of a junction is proposed, which consists of calculating the derivative of the junction capacitance with respect to the angular frequency of the signal corrected by a factor taking into account the band bending and the drop of the ac signal.
