Optimisation of temperature regulator on spray pyrolysis cobalt selenide doped erbium (CoSe: Er) semiconductor material for photovoltaic application

Impact of temperature difference on the features of spray deposited yttrium doped cobalt selenide (YCoSe) thin films for photovoltaic application

“…Numerous researches have been carried out on the deposition, characterization and possible application of metal selenides such as CdSe, CuSe, CoSe, ZnSe, SnSe [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Generally, selenide nano materials have been instrumental in production of photovoltaic, electronics and optoelectronic devices such as laser materials, LEDs, sensors, diodes, transistors, solar cells etc [3,5,[14][15][16]. The selenide material of interest in this research study is the cobalt selenide (CoSe) material which fits into group II-VI of the periodic table.…”

“…To enhance the performance of CoSe nano material several researchers have used the doping technique to make nano materials of Yb:CoSe [5,15], CoSe.MoSe [13], Er:CoSe [3,14], Zr:CoSe [16] prepared using several deposition techniques such as Spray pyrolysis, Electrodeposition, Chemical bath, SILAR [16][17][18][19][20][21][22][23][24]. Imosobomeh et al investigated the impact of temperature on spray synthesized CoSe doped with Zr [16].…”

“…More so, increased thickness at increasing temperature was observed. Cobalt selenide doped with erbium (CoSe;Er) was synthesized by Imosobomeh et al [3]. From the XRD result, decrease in peak intensity as the deposition temperature increases was recorded.…”
