      Recently, the demand of solar cells has rapidly been growing with   an increasing social interest in photovoltaic energy. Improving   the energy conversion efficiency of solar cells by developing the   technology and concepts must be increasingly extended as one of   the key components in our future global energy supplement, but,   the main problem of photovoltaic modules are their rather high   production and energy cost. Hybrid solar cell is an alternative   type of the promising device, which combines the organic   semiconductor as donor material together with inorganic   semiconductor as acceptor material.

      The development of organic-inorganic hybrid solar cells received   widespread attention because of its improved performance due to   nanoscale fabrication of inorganic components and put a path   towards enhanced conversion efficiency by using the most part of   solar spectrum and also cost-effective solar cells.

      In this chapter the principle of hybrid solar cells will be   discussed. And also various kinds of hybrid solar cells based on   silicon will be taken into account. One of the promising   materials is crystalline silicon. Thin film silicon, like no   other thin film material, has been shown to be very useful in   tandem and triple-junction solar cells. Therefore such   multijunction cells, due to their spectrum splitting capability,   have true potential for high conversion efficiency.

      Another section is about amorphous (Protocrystalline) (a-Si) and   microcrystalline silicon solar cells which play an important role   due to their low cost per output energy. Then, the conversion   efficiency will be discussed in multicrystalline and   microcrystalline solar cells. Eventually, the recent developments   such as single-crystalline silicon nanowire hybrid solar cells,   high efficiency micromorph tandem silicon solar cells and hybrid   solar cells based on porous silicon will be mentioned. Suggested   table of content has been presented below.
