Recent technical and commercial successes of existing thin-film solar cell technologies encourage the exploration of next-generation photovoltaic (PV) absorber materials. Of particular scientific interest are compounds that do not exhibit conventional tetrahedral semiconductor bonding, such as CuSbSe<inf>2</inf>. CuSbSe<inf>2</inf>has a 1.1 eV optical absorption onset, a 10<sup>5</sup>cm<sup>−1</sup>absorption coefficient, and a hole concentration of 10<sup>17</sup>cm<sup>−3</sup>. Here, we demonstrate CuSbSe<inf>2</inf>PV prototypes with efficiencies >3%, prepared by a self-regulated sputtering process using a conventional substrate device architecture. Bulk recombination, device engineering issues, and a nonideal CuSbSe<inf>2</inf>/CdS band offset likely limit the promising initial result.
