In photoelectrochemical cells which convert radiant energy to electrical energy the size of the built-in potential Ub is a key quantity. Ub and the flat-band potential, £fb, change with a variation in the redox potential of the electrolyte. Such cha

Adsorption to an organic substrate by a suitable reducible solute influences the magnitude of the hole saturation photo-current and hence the charge-carrier injection efficiency. Efficiencies up to 0.65 have been observed with organic photo-injectors

When seepage of the electrolyte between the semiconductor crystal and its insulation was prevented, the equivalent series capacitance CS of an n-CdTe|Se2-, Sen2-,OH-|Pt cell was almost independent of frequency (

The flat-band potential Efb of n-CdTe in alkaline K2Se solution was determined by the Mott-Schottky technique as a function of properties of the crystal and electrolyte. The experimental value, c.- 2.0 V v. s.c.e., is more negative than the value cal

Metal-insulator-metal cells containing metal-free phthalocyanine sandwiched between two metals (six different combinations of gold, lead and aluminium) have been prepared, and their photoelectrical properties studied in ultra-high vacuum. With irradi

The steady-state electric-field dependence of the intrinsic photoconduction yield in anthracene has been measured for 104 < E < 105 V m-1, the region where yields are reduced compared to those predicted by the Onsager geminate recombination theory. A

Information on the molecular structure of tetracyanoethylene and its mononegative ion is used to derive the electron affinity of tetracyanoethylene from the experimentally determined threshold energy for photodetachment of electrons from the negative

Although aqueous electrodes have been used often to discharge positive holes emerging from an anthracene crystal, the mechanism has not yet been elucidated in any one case. We have found that p-anilinobenzenesulphonate (1) prevents all oxidation of t

Thin films containing cadmium and tellurium, not necessarily present as the compound cadmium telluride, were electrodeposited galvanostatically onto a titanium rotating disc electrode from an aqueous solution containing CdS04, TeO2 and H2SO4. The fil
