Popis:	A photovoltaic SeCdO thin film cell has been fabricated by reactive sputtering of CdO on a crystallized selenium film using a cadmium target in the presence of argon plus residual air. Critical control of pressure is needed to obtain the appropriate excess of cadmium in the CdO to realize low enough resistivity coupled with sufficient transparency. The spectral response lies between 350 and 700 nm and is controlled on the long wavelength side by the selenium and on the short wavelength side by the CdO. The CdO dominates the series resistance, so that the resistivity of the selenium is unimportant. A recent improvement in the fabrication process has resulted in an increase of cell conversion efficiency to about 1.7%, which is well above values observed on commercial selenium photovoltaic cells. Some preliminary experiments have been made to sputter CdO reactively on glass from gas pre-mixtures of oxygen and argon to obtain easier pressure control.
