“…In alkaline medium, CdO and TeO 2 easily dissolve in the medium, while the remaining Mn(OH) 2 is converted to the Mn 3 O 4 or Mn 2 O 3 state. 6 Figure 4 shows Raman spectroscopy data for the passivated surfaces obtained with the two passivants, and for the sample left in air. We discerned peaks located at 331 cm À1 , 713 cm À1 , 728 cm À1 , and 771 cm À1 .…”

Passivation is an important process that reduces surface leakage current and its attendant noise. We treated detector-grade large-volume CdMnTe:In samples with an (NH 4 )-based passivant, and compared the results with untreated samples by measuring current-voltage characteristics, surface recombination velocity, Raman spectroscopy, and charge-collection mapping. The leakage current of the passivated CdMnTe (CMT) detectors decreased five to ten times, and surface recombination declined five to six times, depending on the passivation conditions applied. We satisfactorily explained these improvements in detector performance as resulting from different passivation layers that were generated by distinct chemical reactions, as determined by the pH of the passivant.

This chapter endeavors to bring to the reader the potential of electrochemical deposition processes to develop low cost solar cells. The targeted photovoltaic absorbers are largely inorganic compound semiconductors containing earth abundant elements and satisfying the physical criteria of band gap and dopability. Electrodeposition, being an well established chemical process having its inherent capability for a large productions, should also be applied to develop various low cost solar cells, such as Cu ZnSnS , Cu S, FeS , Zn P , few/mono-layer MoS and WS etc having direct band gaps and ability to engineer their band gap through in-situ doping for creating various possible hereojunctions. The author believes that the combined effort of electrochemistry, physics and chemical engineering can push this simple and ultra-low cost technique of electrodeposition along with other supporting solution based techniques to produce PV energy at most affordable price in coming days.
