Solid-state dye-sensitized solar cells

Donor-acceptor polymer for the design of All-Solid-State dye-sensitized solar cells

“…Solid state hole transporting material (HTM)-based DSSC, termed as all solid-state DSSC (SDSC), has overcome the liquid electrolyte problems [17], but facing the challenge of modest conversion efficiency [18,19]. Some HTM has a weak interaction with the dye which leads to the interruption of the hole-conducting path between HTM and dye molecule.…”

Tin oxide based dye-sensitized solid-state solar cells: surface passivation for suppression of recombination

“…In the first reported DSSC [1] and the ETA cell [6], this requirement was achieved by an ingenious film fabrication procedure involving multiple application and sintering of a especially prepared TiO 2 paste on conducting tin oxide glass [1,6]. Later, a more convenient method of depositing a blocking layer and an upper screen printed layer was adopted [14].…”

Fabrication of fairly efficient solid state dye-sensitized solar cells with a dense blocking layer

“…It is well known that compactness of the blocking layer dominates performance of SSDSSCs. 26) However, a precursor of the titanium alkoxide which has been usually used for the formation of blocking layer is useless to prepare dense blocking layers, since cleavage due to decomposition and evaporation of bulky alkoxy groups during heat-treatment may be left in the layer. 26) In this paper, we propose better method for preparation of the dense TiO 2 blocking layer on FTO through an alkoxy group free precursor.…”

By the use of the present method, it is found that CuI based SSDSSCs with the dense TiO 2 blocking layer shows enhancement in the conversion efficiency (©) mainly due to the improvement of the short-circuit current (Jsc).…”
