We are presenting porous-structured ZnO films grown by two-step chemical bath deposition (CBD), which has the potential to be used as a porous electrode in dye-sensitized solar cells (DSSCs). ZnS films were deposited on corning glass substrates by a stirred aqueous solution. Subsequent oxidization of ZnS films gave rise to ZnO thin films. The ZnO films exhibited a strong (002) diffractive peak, which...
This paper describes our progress achieved in thin-film free-standing monocrystalline silicon (FMS) solar cells by layer transfer process using porous silicon. The highest cell efficiency achieved for a 1times1 cm2 FMS solar cell is 13.5% with an open circuit voltage Voc=612 mV, current density Jsc =28.9 mA/cm2 and fill factor of FF=76.7%. In the effort of scaling-up of the cell area, the lift-off...
