Design and Simulation of a Highly Efficient InGaN/Si Double-Junction Solar Cell

A solar cell is an electronic device which not only harvests photovoltaic effect but also transforms light energy into electricity. In photovoltaic phenomenon, a P-N junction is created to form an empty region.  The presented paper aims at proposing a new highly efficient InGaN/Si double-junction solar cell structure. This cell is designed to be used in a real environmental situation, so only s...

Co-diffused Apcvd Boron Rear Emitter with Selectively Etched-back Fsf for Industrial N-type Si Solar Cells

The employment of a B-doped atmospheric pressure chemical vapor deposited (inline belt APCVD) borosilicate glass is an elegant technology for industrially realizing a p emitter. By drive-in of B and a subsequent POCl3 co-diffusion, p emitter and n front surface field (FSF) are established in a single process step. APCVD-SiOx is used to prevent the p emitter from being compensated during P diffu...

Screen-Printed Al-Alloyed Rear Junction Solar Cell Concept Applied to Very Thin (100Î1⁄4m) Large-Area n-Type Si Wafers

Reducing the thickness of crystalline Si wafers processed to solar cells returns two significant benefits. Firstly, processing cost is reduced by saving costand energy-intensive Si material. Secondly, the required diffusion length of minority carriers is smaller, thus, wafers with a smaller carrier lifetime (e.g. due to higher base doping) can be utilized. In this work, the industrially feasibl...
