FLEXIBLE SOLAR CELL WITH BACK-SIDE BUFFER LAYER.

摘要

The present invention relates to a flexible solar cell having a flexible substrate, which can improve photoelectric conversion efficiency because the sunlight reaches a light absorbing layer without any loss and without passing through a buffer layer, a front electrode, and a grid electrode by having a backside buffer layer and which enables an electron-hole generated by the light absorbing layer to shorten a moving distance to the electrode or the buffer layer by preparing the buffer layer and a first electrode to be engaged with each other in a sawtooth form.
