A study was conducted on the improvement of power generation for a window by solar radiation reflected from Low-E coat of a semi transparent photovoltaic module. This module is composed of a double-glazing that be installed a low-E glass in the indoor side and a solar module equally arranged linear double-sided solar cells in the outdoor side. As a result of outdoor verification, it was confirmed that annual power generation by Low-E coat increased by about 9%. The simulation also shows that there is a power generation advantage against the model using the square cell.
