(Color online) Schematic cross section of a DJ Si-based thin film solar cell on glass substrate.
(Color online) AFM images of textured AZO films applied to (a) DJ H and (b) DJ L cells.
(Color online) Total transmittance and haze (diffused/total transmitted) values of textured AZO films applied to DJ H and DJ L cells.
(Color online) J-V characteristics of DJ H and DJ L cells.
(Color online) Emission intensity distribution of DJ cells using EL measurement; (a) optical image of the device; left line (cathode cable) and right one (anode cable). EL image of (b) DJ H and (c) DJ L.
(Color online) c-AFM image showing 30 × 30 μm2 surface scan depicting (a) the topography and (b) the current map of DJ L cell. The bias applied to the cell was −1 V. In the current map, brighter regions correspond to higher negative current, i.e., more conductive regions.
(Color online) Cross sectional TEM images of a-Si:H/a-SiGe:H/Ag on AZO film in DJ L cell. Nanocrack defects were shown in (a) pinhole and (b) highly textured surface of AZO films.
Solar cell parameters of DJ H and DJ L cells.
