摘要： Disclosed are a transparent electrode for a solar cell and a method of manufacturing the same. The transparent electrode for a solar cell has a low Young's modulus, excellent elasticity, self-healing properties, an average visible-light transmittance sufficient to implement bifacial properties, and excellent power conversion efficiency (PCE). In addition, the method of manufacturing the transparent electrode for a solar cell does not require an additional deposition process, so the electrode-manufacturing time can be reduced, and the electrode-manufacturing process can be performed separately from other solar-cell-manufacturing processes, which is advantageous for mass production and large-area application.

摘要： A tantalum capacitor includes a sintered tantalum body including tantalum powder, a conductive polymer layer disposed on the sintered tantalum body and including a first filler, a carbon layer disposed on the conductive polymer layer; and a tantalum body including a tantalum wire penetrating through at least a portion of each of the sintered tantalum body and the conductive polymer layer in a first direction. A ratio of an area of the first filler to an area of the conductive polymer layer is greater than 0.38 in a first cross-section partially overlapping the sintered tantalum body, among cross-sections perpendicular to the first direction.
