Hydrogenated amorphous silicon transverse junction solar cell

Abstract
In this letter, we introduce a new thin film solar cell design on amorphous silicon, called the transverse junction solar cell. In this concept, the p-i-n junction is formed perpendicular to the surface. With conventional deposition and silicon device processing techniques test cells have been made with a conversion efficiency up to 5.2%±1.4% under standard AM1.5 illumination.
