Provided is an electronic device including a plurality of substrate electrodes on a substrate, the substrate electrodes including initial electrodes and spare electrodes, a bonding material covering the initial electrodes and the spare electrodes, module structures respectively provided on first initial electrodes of the initial electrodes, and solders between each of the first initial electrodes and each of the module structures, wherein the spare electrodes include second spare electrodes, wherein the module structures are not provided on the second spare electrodes, wherein the bonding material on the first initial electrodes is harder than the bonding material on the second spare electrodes.

Electronic device and its repair method

Provided is a method for manufacturing an electronic device. The method for manufacturing the electronic device includes mapping good elements and defective elements on a substrate, providing a first transparent structure including a first adhesive layer on the substrate, selectively providing first laser light to the defective elements to cure the first adhesive layer on the defective elements and separate the defective elements from the substrate, providing a second transparent structure including a second adhesive layer, which adheres to new elements replaced for the defective elements, on the substrate, and selectively providing second laser light to the new elements to bond the new elements to the substrate.

Method of manufacturing electric device

Provided are a dye-sensitized solar cell and a method of fabricating the same. The dye-sensitized solar cell includes an electrode structure including a conductive layer having pores that are regularly arranged, a semiconductor oxide layer disposed on a surface of the conductive layer, and a dye layer disposed on a surface of the semiconductor oxide layer.

Dye-sensitized solar cell and method of fabricating the same

There is provided a system for cleaning a surface of a solar cell panel. The system includes a measurement unit measuring a power generation value of a solar cell panel, a reference unit providing a reference value, a control unit comparing the power generation value measured at the measurement unit with the reference value provided from the reference unit to command cleaning of the solar cell panel, a driving unit operating a cleaning apparatus for cleaning a surface of the solar cell panel. The control unit commands cleaning of the solar cell panel only when the power generation value decreases because of a contamination of the surface of the solar cell panel.

System for cleaning surface of solar cell panel

The present invention provides a transceiver module having advantages of minimizing the number of optical parts by using an optical collimator to which a lens having the same shape as a diameter of an optical fiber is attached on a light input/output end. An transceiver module according to the present invention includes, laser diode for generating an optical signal to transmit, a first photodiode for controlling the laser diode, a second and third photodiodes for receiving an optical signal of a first and second wavelengths, and an optical collimator formed at a light input/output end. On the optical collimator, a lens having an optical fiber shape is attached in a direction the light proceeds.
