A method of repairing a solar cell bonded on a substrate, by bonding a replacement solar cell on top of an existing solar cell, without removing the existing solar cell. The substrate may comprise a flexible circuit, printed circuit board, flex blanket, or solar cell panel. The bonding of the replacement solar cell on top of the existing solar cell uses a controlled adhesive pattern. Electrical connections for the existing solar cell and the replacement solar cell are made using electrical conductors on, above or embedded within the substrate. The electrical connections may extend underneath the replacement solar cell. The method further comprises removing interconnects for the electrical connections for the existing solar cell, and then welding or soldering interconnects for the electrical connections for the replacement solar cell.

Example embodiments relate to controlling detection time in photodetectors. An example embodiment includes a device. The device includes a substrate. The device also includes a photodetector coupled to the substrate. The photodetector is arranged to detect light emitted from a light source that irradiates a top surface of the device. A depth of the substrate is at most 100 times a diffusion length of a minority carrier within the substrate so as to mitigate dark current arising from minority carriers photoexcited in the substrate based on the light emitted from the light source.

A division device includes a platform, a withstanding element and a pressure element. The platform has a platform surface. The withstanding element, located on the platform surface, has at least one shrink-top-type withstanding structure protruding from the platform surface and extending along a withstanding line. The shrink-top-type withstanding structure is to withstand the solar cell sheet. The pressure element, located above the platform, has two forcing portions protruding toward the platform. While the solar cell sheet is under dividing, a back surface of the solar cell sheet opposing to the front surface is arranged to face the shrink-top-type withstanding structure by aligning the trench with the withstanding line, and then the two forcing portions are introduced to apply predetermined depression individually onto the two solar cell units, such that the solar cell sheet are divided into the two separate solar cell units.
