Abstract

The photovoltaic cell comprises, deposited on a transparent substrate in the following order: a first conductive oxide layer; a first p-i-n junction; a second p-i-n junction; a second conductive oxide layer, wherein said first conductive oxide layer is substantially transparent and comprises a low-pressure chemical vapor deposited ZnO layer; and said second conductive oxide layer comprises an at least partially transparent low-pressure chemical vapor deposited ZnO layer; and wherein said first p-i-n junction comprises in the following order: a layer of p-doped a-Si:H deposited using PECVD and having at its end region facing toward said second p-i-n junction a higher band gap than at its end region facing toward said first conductive oxide layer; a buffer layer of a-Si:H deposited using PECVD without voluntary addition of a dopant; a layer of substantially intrinsic a-Si:H deposited using PECVD; a first layer of n-doped a-Si:H deposited using PECVD; and a layer of n-doped μc-Si:H deposited using PECVD; and wherein said second p-i-n junction comprises in the following order a layer of p-doped μc-Si:H deposited using PECVD; a layer of substantially intrinsic μc-Si:H deposited using PECVD; and a second layer of n-doped a-Si:H deposited using PECVD. The photovoltaic converter panel comprises at least one such photovoltaic cell.
