Semitransparent
solar cells, which can be incorporated in windows,
façades, and skylights, change a part of incident light to
electric power while allowing the rest to pass through. Improving
the conversion efficiency and visible-light transmittance of such
devices is a crucial factor for power-generating window applications.
Herein, we report the fabrication of semitransparent single-junction
and tandem devices using microcrystalline silicon (μc-Si) with
front and rear transparent conducting oxide electrodes by plasma-enhanced
chemical vapor deposition. The material properties of the p-doped
silicon-carbide (SiC) films and the interfaces between p-layer and
intrinsic μc-Si were optimized to enhance the solar cell performance.
By using highly crystalline seed layers for the intrinsic μc-Si
absorbers and controlling the properties of high-bandgap p-SiC films,
high power conversion efficiency (PCE) and average visible transmittance
(AVT) of 4.71 and 12.31%, respectively, were simultaneously obtained
for the semitransparent devices using 1000-nm-thick μc-Si absorbers.
Their performance at different low light intensities was also investigated.
The devices showed steady PCEs of 4.37–4.71% at low light intensities
(100–21 mW/cm2). Enhanced PCE of 7.51% and AVT of
11.00% are achieved in high-quality semitransparent tandem devices
with amorphous silicon and μc-Si subcells. The corresponding
tandem solar cells showed further increased PCE of 9.00% under bifacial
illumination condition.
