The semiconductor-sensitized thermal cell (STC) is an attractive technology that used low-temperature heat (<200 °C). STC generates electricity by the redox reactions of electrolyte ions with thermally excited carriers in semiconductors. The most valuable feature of the STC is that, after power generation was completed, the performance recovers by leaving the cell in the heat source. However, the reason for this restore has been unclear. In this study, the recovery phenomenon was investigated with the viewpoint of electrolyte thickness. As a result, the cell with the thinnest thickness and smallest quantity of electrolyte discharged for the longest time, with faster recovery and better discharge characteristics. These consequences clearly demonstrated the difference between primary batteries and STCs.

“…Various theories and models have been put forward to interpret CTTs with different features. Among these models, Scharifker-Hills (S-H) model [26] is suitable for the treatment of CTTs with a well-defined maximum [8,11,[14][15][16][17][25][26][27][28][29][30]. The CTTs measured from acid sulfate baths in the absence and presence of MPS additive combinations at different potentials from -0725 to -0.850 V are shown in Fig.…”

“…High nuclei number density is favorable to the microvia filling without void. With regard to a three-component additive package, effects of PEG [8,11,[14][15][16], Cl [8,16,17], PEGCl [11,[15][16][17], and PEG-Cl-SPS [8,18] on copper electrocrystallisation have been studied. It has been found that the nucleation of copper in an acidic sulfate solution follows an instantaneous nucleation together with a 3-dimensional growth mechanism.…”

Copper electrodeposition and nucleation on a glassy carbon electrode from acid sulfate electrolytes in the presence of 3-mercapto-1-propanesulfonate sodium salt (MPS) and its combinations with chloride ions (Cl) or/and polyethylene glycol (PEG) were investigated by utilizing cyclic voltammetry (CV), chronoamperometry (CA) and scanning electron microscopy (SEM). CV results indicate that MPS and MPS-PEG inhibit whereas MPS-Cl and MPS-PEG-Cl accelerate copper deposition. CA and SEM results suggest that copper nucleation follows an instantaneous nucleation mechanism with three-dimensional growth from all baths at the studied deposition potentials. The copper nucleation rate and nuclei number density are increased greatly in the MPS-Cl and MPS-PEG-Cl baths.
