The effective design of semi-transparent (semi-transparent, ST) solar cells (solar cell, SC) has made it possible to implement energy-generating window applications for new generation homes and automobiles that need energy. In particular, building-integrated photovoltaic technology is becoming one of the more effective techniques for powering renewable energy in buildings. The ST-SC design not only works as a generator but also allows natural light to pass through, reducing electricity consumption. The applications of ST-SCs to social living areas are smart and healthy home technologies that can receive sunlight. However, the requirements to be designed as ST include parameters that limit the absorption in the visible region and thus the photovoltaic cell performance. Therefore, ST-SCs designed with material systems such as CdTe that can already achieve high efficiency can be a solution to this design limitation. In this study, it was investigated how the thickness of CdTe, which is the absorber layer for a CdTebased SC designed as ST, affects ST properties, color, and photovoltaic cell performances. All optical calculations were calculated by the Transfer Matrix Method. As the thickness of the CdTe absorber layer increases from 25 nm to 225 nm, the average apparent transmittance decreases from 49.86% to 10.45%. In addition, the increase in thickness for CdTe increases the photocurrent density and shifts the SC color from the Planckian locus to the red-orange region.
