Spray-deposited ITO-CdTe solar cells

Nb-doped TiO2 thin films for photovoltaic applications

“…In this device, the CdTe (111) face was etched in bromine methanol prior to loading into vacuum for In 2 O 3 deposition. The CdTe crystal had a carrier concentration of 6 × 10 15 /cm 3 . The open circuit voltage of this cell remains the highest ever reported for a CdTe device.…”

Solar Cells on the Base of Semiconductor-Insulator-Semiconductor Structures

“…In SC fabrication the most utilized TCO materials are tin oxide, indium oxide and their mixture known as indium tin oxide (ITO). Thin ITO layers have been deposited onto different semiconductors to obtain SIS structures: Si (Malik et al, 1979), InP (Botnariuc et al, 1990), CdTe (Adeeb et al, 1987), GaAs (Simashkevich et al, 1992). Therefore, solar cells fabricated on the base of SIS structures have been recommended as low cost photovoltaic solar energy converters.…”

“…ITO/CdTe (Adeeb et al, 1987) and ITO/GaAs (Simashkevich et al, 1992) structures were obtained by spray pyrolysis of ITO layers on pCdTe and pGaAs crystals. For ITO/CdTe the efficiency was 6%, for ITO/GaAs SC it did not exceed 2.5%.…”

“…Basic investigations of the ITO/Si SIS structures have been carried out and published in the USA (DuBow et al, 1976;Mizrah et al, 1976;Shewchun et al, 1978; Theoretical and experimental aspects of the processes that take place in these structures are examined in those papers. Later on the investigations of SC based on SIS structures using, as an absorber component, Si, InP and other semiconductor materials have been continued in Japan (Nagatomo et al, 1982;Kobayashi, et al, 1991), India (Vasu & Subrahmanyam, 1992;Vasu et al, 1993), France (Manifacier & Szepessy, 1977;Caldererer et al, 1979), Ukraine (Malik et al, 1979;Malik et al, 1980), Russia (Untila et al, 1998), the USA (Shewchun et al, 1980;Gessert et al, 1990;Gessert et al, 1991), Brasil (Marques & Chambouleyron, 1986) and the Republic of Moldova (Adeeb et al, 1987;Botnariuc et al, 1990;Gagara et al, 1996;Simashkevich et al, 1999). The results of SIS structures fabrication by different methods, especially by pyrolitic pulverization and radiofrequency sputtering, are discussed in those papers.…”
