An overview is given concerning current industrial technologies, near futur
e improvements and medium term developments in the field of industrially im
plementable crystalline silicon solar cell fabrication, The paper proves th
at considerable improvements are still possible, both in efficiency and in
production cost. The paper also proves that a lot of effort is being put wo
rldwide on thinner substrates and on thin-film crystalline silicon cells de
posited on cheap carriers, in order to save in substrate cost and in order
to gain more independence from availability problems of silicon feedback.
