The effect of temperature on the performance parameters [short-circuit current density (J(SC)), open-circuit voltage (V-OC), fill factor (FF), and conversion efficiency (eta)] of stand-alone germanium (Ge) solar cells has been theoretically investigated. Although J(SC) increased with increasing temperature, eta decreased due to a decrease in V-OC and the associated decrease in the FF. The performance parameters J(SC), V-OC, FF, and eta of a fabricated stand-alone Ge solar cell were determined from current-voltage (I-V) measurements. The significant differences between the obtained theoretical and experimental data may be related to both the use of idealized cases in the theoretical studies and the loss mechanisms considered to adversely affect the performance of the fabricated stand-alone Ge solar cell.
