“…9) In general, high efficiencies are achieved with long lifetimes of carriers in the absorption layer. 10) Thus, a high carrier mobility, thus, is necessary to enhance the efficiency. CdTe films have a high hole mobility (1540 cm 2 V ¹1 s ¹1 ) that contributes to a great efficiency.…”

The optical and electrical properties of MnTe films were investigated to ascertain the feasibility of their use in solar cell applications. Three ¡-MnTe thin films with different composition, i.e., Mn-47.9 at% Te, Mn-49.2 at% Te, and Mn-50.4 at% Te, were prepared using RF magnetron sputtering. All the films demonstrated a high light absorption coefficient (0.2 © 10 5 0.8 © 10 6 cm ¹1) and an optimal indirect band gap (1.37 1.52 eV) for solar cell applications. Furthermore, all of them exhibited p-type conductivity, with the Mn-47.9 at% Te film demonstrating three to four times higher carrier mobility (5.2 cm 2 •V ¹1 •s ¹1) than the Mn-50.4 at% Te film (1.6 cm 2 •V ¹1 •s ¹1).

Photoluminescence imaging techniques have recently been extended to silicon bricks for early production quality control and electronic characterisation in photovoltaics and microelectronics. This contribution reviews the state of the art of this new method which is fundamentally based on spectral luminescence analyses. We present highly resolved bulk lifetime images that can be rapidly extracted from the side faces of directionally solidified or Czochralski grown silicon bricks. It is discussed how detailed physical modelling and experimental verification give good confidence of the best practice measurement errors. It is also demonstrated that bulk lifetime imaging can further be used for doping and interstitial iron concentration imaging. Additionally, we show that full spectrum measurements allow verification of the luminescence modelling and are, when fitted to the theory, another accurate method of extracting the absolute bulk lifetime.
