Since its invention in the 1950s, semiconductor solar cell technology has evolved in great
leaps and bounds. Solar power is now being considered as a serious leading contender for …

This chapter reviews the field of silicon solar cells from a device engineering perspective,
encompassing both the crystalline and the thin-film silicon technologies. After a brief survey …

To optimize the optical response of a solar cell, specifically designed materials with
appropriate optoelectronic properties are needed. Owing to the unique microstructure of …

Besides passivation of the c-Si absorber, provided mainly by the undoped buffer layer, the
net do** of the silicon thin films plays a major role in the performance of silicon-based …

One of the most limiting factors in the record conversion efficiency of amorphous/crystalline
silicon heterojunction solar cells is the not impressive fill factor value. In this work, with the …

Non‐stoichiometric nickel oxide (NiOx) is attracting growing attention due to its
characteristics of p‐type transparent conductive layer and to the possibility to tailor its optical …

We present and discuss advances in the development of p-type Si heterojunction solar cells
with Al-doped ZnO (AZO) on both front and rear side, by means of mixed-phase Si-and SiO x …

Substoichiometric molybdenum oxide (MoO x) has good potential as a hole-collecting layer
in solar cells. In this paper, we report on the application of ultrathin evaporated MoO x as a …

Hole-collecting and buffer layers more transparent than amorphous silicon layers are
regarded as one of the possible improvements needed in amorphous/crystalline silicon …

The adoption of a-SiO x: H films obtained by PECVD in heterojunction solar cells is a key to
further increase their efficiency, because of its transparency in the UV with respect to the …
