PHOTOVOLTAIC MODULES HAVING A BUILT-IN BYPASS DIODE AND METHODS FOR MANUFACTURING PHOTOVOLTAIC MODULES HAVING A BUILT-IN BYPASS DIODE

摘要

A photovoltaic device includes: a substrate; lower and upper electrode layers disposed above the substrate; and a semiconductor layer disposed between the lower and upper electrode layers, the semiconductor layer absorbing incident light to excite electrons from the semiconductor layer, wherein the semiconductor layer includes a built-in bypass diode extending between and coupled with the lower and upper electrode layers, the bypass diode permitting electric current to flow through the bypass diode when a reverse bias is applied across the lower and upper electrode layers.
