The optimization of these parameters makes it possible to improve the performances of the solar cell of type n-ZnO/n-CdS/p-Cu (In, Ga) Se2. We use a broad range of reflection going from 0%, use of ideal anti-reflecting layer, to a reflection of 80% which corresponds to a very weak absorption. We note that with the use of an \"ideal\" anti-reflecting layer, we obtained a short circuit current density of 0.0325mA.cm-2, an open circuit voltage of 0,8337V, a maximum power of cell of 0.0233mW and a maximum value of the external quantum efficiency of 99.29%.  However these physical parameters are deeply affected by the external front reflection. All the physical parameters studied decrease considerably.  We find for a front reflection of 80%, a short circuit current density of 0.0065mA.cm-2, an open circuit voltage of 0,7923V, a maximum power of cell of 0.0045mW and a maximum value of the external quantum efficiency of 19.86%.<#LINE#>Ehemba A.K., Dieng M., Diallo D. and Sambou G.

After studying several papers it is concluded that  existing system is very complex in design so in this paper this will be reduce by combination of sensors and controllers this all are so adjusted that it looks like a simple device and can be understand easily. This segway consist of accelerometer, gyroscope, tilt sensor and motor driver, ADC and micro controller 2051.assembly is made by wooden cart board. This is simple inverted pendulum based robot which will carry the things in bad surface area for transportation purposes (wireless control). In this paper here it tries to reduce the cost of overall system because now a day’s their cost of a segway is very high so with this project it can be reduced with simpler design configuration. Because if simpler the design means we are removing some redundant and less used part. Now available segway has lots of complexicity in design in this project it will be reduced.<#LINE#>Hao Huang Chao and Wang Wen June and Chiu CH (2011).@Design & implementation of fuzzy control on two wheeled inverted pendulum.@IEEE Transactions On Industrial Electronics, 58(7).@Yes$Colton Shane (2008).@DIY self-balancing scooter.@Spring, 17.@No$Sultan Khalil and Mirza A.
