Strategy to improve the efficiency of tin selenide based solar cell: A path from 1.02 to 27.72%

Electrical and Optical Properties of γ-SnSe: A New Ultra-narrow Band Gap Material

“…The γ-SnSe phase can also be utilized to form an ohmic contact between the absorber and the back contact metal in α-SnSe-based solar cells, which are very sensitive to the formation of a Schottky barrier there. 59 The new chemical and physical properties along with these potential applications make this phase an exciting new material that will be subject to further studies.…”

The ultra-high thermoelectric power factor in facile and scalable single-step thermal evaporation fabricated composite SnSe/Bi thin films

“…36,37 The fabrication of SnSe thin films has also engrossed researchers' interest due to a wide variety of applications. [38][39][40][41][42][43][44] Burton et al 45 reported the first thermoelectric generator based on a SnSe film as p-type and Ag as n-type legs with an output power of 0.09 mW (at 618 K) by the thermal evaporation method. A pure SnSe thin film exhibits a very low ZT of 0.055 at 501 K. A further enhancement in ZT is reported by Burton et al 35 using a 3D printing technique.…”

Exploring the optoelectronic properties of SnSe: a new insight

“…Although the thickness of layers plays a vital role in the device in terms of homogeneity of the layers, cell efficiency seems insensitive to the thickness of the buffer and window layers. After optimizing the buffer and window layer parameters, when the absorber layer is optimized with selected parameters ( N V , N C , RRC, electron and hole mobility of 2.2 × 10 15 cm −3 , 1.8 × 10 16 cm −3 , 1 × 10 −6 , 1000 cm 2 s −1 V −1 and 100 cm 2 s −1 V −1 , respectively) given in the previous report 44 (with 50 nm thickness for the SnSe 2 and SnO 2 layers), the efficiency of the cell reaches up to 20.28% (Fig. S7, ESI†).…”

“…Solar cell based on SnSe and Si had a maximum efficiency of around ∼6.44% 43 and SnSe has the potential to reach up to 27.7%. 44 Theoretical and experimental demonstration of the as-obtained solar cell device is presented. The simulation program SCAPS-1D was used for the theoretical investigation of the performance of the natural device.…”
