    摘要： Embodiments described herein relate generally to apparatuses and processes for forming semi-solid electrodes having high active solids loading by removing excess electrolyte. In some embodiments, the semi-solid electrode material can be formed by mixing an active material and, optionally, a conductive material in a liquid electrolyte to form a suspension. In some embodiments, the semi-solid electrode material can be disposed onto a current collector to form an intermediate electrode. In some embodiments, the semi-solid electrode material can have a first composition in which the ratio of electrolyte to active material is between about 10:1 and about 1:1. In some embodiments, a method for converting the semi-solid electrode material from the first composition into the second composition includes removing a portion of the electrolyte from the semi-solid electrode material. In some embodiments, the method includes mechanically compressing the intermediate electrode to remove the portion of electrolyte from the semi-solid electrode material.

    摘要： The solar cell element includes a semiconductor substrate with first and second surfaces, a passivation layer located on the second surface, a protective layer located on the passivation layer, and a back-surface electrode located on the protective layer. The back-surface electrode is electrically connected to the semiconductor substrate via one or more hole portions penetrating the protective layer and the passivation layer. The protective layer includes a first region showing a tendency to increase in thickness as a distance from an inner edge portion of the hole portion and a second region surrounding the first region. A distance between a position of the first region farthest from the inner edge portion and the inner edge portion is larger than a thickness in the second region. The back-surface electrode shows a tendency to decrease in thickness on the first region as a distance from the inner edge portion.

    摘要： A solar cell includes elements, a connecting portion, and a transparent portion. The elements include first and second elements arrayed in a first direction. The transparent portion is located between the connecting portion and the second element. Each of the elements includes first and second electrode layers and a semiconductor layer interposed between the first and second electrode layers. Between the first element and the second element, their first electrode layers sandwich a first gap and their second electrode layers sandwich a second gap shifted in the first direction from the first gap. The connecting portion electrically connects the second electrode layer of the first element to the first electrode layer of the second element. The transparent portion is located between the second electrode layer of the first element and the first electrode layer of the second element at a position shifted in the first direction from the connecting portion.
