Abstract

See full text

One embodiment of the present invention provides a solar cell. The solar cell includes a base layer comprising crystalline Si (c-Si), a hole collector situated on a first side of the base layer, and an electron collector situated on a second side of the base layer, which is opposite the first side. The hole collector includes a quantum-tunneling-barrier (QTB) layer situated adjacent to the base layer and a transparent conducting oxide (TCO) layer situated adjacent to the QTB layer. The TCO layer has a work function of at least 5.0 eV.
