The optimized condition of all-back-contact solar cells is studied to eliminate the problem of light blocking by the front contacts in conventional solar cells. The influences of layer thickness and pitch distance are studied. The optimized structure is obtained with a 2 μm thick base layer and a 631 μm contact pitch, and the efficiency can reach to 26.15%.
