Heinz-Otto Kreiss,Hedwig Ulmer Busenhart based on selenium in 1876 [1]. It took more than a half a century for the creation of the first solar cells with an efficiency barely exceeding 1%. These were thallium sulfide photocells with a rectifying region [2]. The investigations were carried out under the leadership of Academician A.F. Ioffe

In 1995 this technology demonstrated its suitability to produce cells in the conventional 1-sun production line able to operate under 3W/cm2 at 18% efficiency [3].
