Abstract : Our research work on high-efficiency silicon solar cells first of all began with raising circuit voltage as well as assisting with certain measures to improve short circuit current density and fill factor. The cells which were developed had their total surface area efficiency measured at 18.7% in evaluation tests at the Solar Research Institute in Colorado. This is the highest value obtained by a silicon cell measured at this institute. It is a relatively large improvement compared to the efficiency of silicon cells measured by similar methods previously published. As a result of using such measures as surface passivation technology, circuit voltage has been increased. As a result of high circuit voltage and low series resistance extremely high fill factors have been achieved. As a result of employing designs such as double layer, anti-reflective film and decreasing electrode shading area, short circuit current density has been increased.
