In this research, the development of three (3) low-cost adsorbent materials from abundant waste rice husk was achieved via thermal treatment.
Consequently, there has been a growing interest in developing and implementing various potential adsorbents for the removal of phenol from water, and researchers are always in a hunt for developing more suitable, efficient, cheap and easily accessible types of adsorbents, particularly from the waste materials.
Material and Methods Development and characterization of Adsorbents.
The raw material, rice husk (RH), was obtained from a nearby rice mill.

ACA comes from the simulation process of the foraging behavior of ants on the nature .Ants in motion would leave a kind of material called pheromone on the way they passed through ,so the ants behind can choose their path according the pheromone that the ants before left .The more pheromone is left with more ants before passed through ,the greater probability which the ants choose the same path .This collective behavior of ants actually constitutes a positive feedback phenomenon of learning information ,so the ants could get to the food in the shortest path through this exchange of information[10] .Benefit from this optimization mechanism ,ACA expressed the solution of the problem as a ordered matrix , just like the ant moves between adjacent nodes releasing of pheromone ,and with this guidance the ants behind can choose the next adjacent node ,gradually builds a feasible solution ,finally finds the optimal solution by exchange of information and mutual cooperation between individuals[11,12

There are many kinds of solar cells, such as Mono-crystalline Silicon, Multi-crystalline Silicon, Amorphous Silicon, Film Photovoltaic, and compound semiconductor etc. among which the characteristics of Film Photovoltaic solar cell include material saving and another major of less number of processes which can be manufactured by large area continuously; from raw material input to module export, it takes two and a half hours only.
Since various solar cells in actual power efficiency are different, this research used three different solar cells set up at top floor, 7F of Comprehensive Science Building in National Taipei University of Technology to carry out the experiment for efficiency of power generation in different sunshine environment and analyze its result.
Introduction of various solar cells Presently, the major raw material of most solar cells in the world is silicon (Si), among which the most are Mono-crystalline Silicon, Multi-crystalline Silicon and Amorphous Silicon.
Because the drawback of such material is less, so the conversion efficiency of photovoltaic energy is higher; however, its cost is relatively high.
Nevertheless, Thin Film Silicon solar cells use less silicon materials, with shorter payback period of manufacturing energy and form a translucent glass curtain integrated into construction materials.
