    • Effect of TiO2 thickness on dye sensitized solar cell performance 

      Muhammad Irwanto, Misrun, Dr.; Muhammad Fitra, Zambak; Shasidharan, Gomesh Nair; Mohd. Irwan, Yusoff (Institute of Electrical and Electronics Engineers (IEEE), 2013-06)
      A dye solar cell with a dimension of 6 × 2 cm is fabricated with thickness of 40 μm, 80 μm and 120 μm of TiO2 by smearing it on an ITO coated glass. It is then tested under the average solar irradiance and temperature of ...

    • Maximum voltage angle optimization of uninterruptible power supply on three-level transformer-less photovoltaic inverter 

      Muhammad Irwanto; Mohd Irwan, Yusoff; Gomesh Nair, Shasidharan; Noor Syafawati, Ahmad (Institute of Electrical and Electronics Engineers (IEEE), 2012-05)
      his paper presents a new topology of three-level transformer-less photovoltaic (PV) inverter. In this topology, a 240V AC system is developed from a full bridge inverter circuit using PIC microcontroller (PIC16F628A-I/P) ...

    • Power capacity enhancement of transformerless photovoltaic inverter 

      Muhammad Irwanto, Misrun, Dr.; Shasidharan, Gomesh Nair; Mohd. Irwan, Yusoff; Muhammad Fitra, Zambak (Institute of Electrical and Electronics Engineers (IEEE), 2013-06)
      A conventional inverter uses a transformer. Some transformers connected in parallel are needed to obtain a high power inverter. They cause the inverter has a big in size, expensive cost and low efficiency. To solve the ...

    • Review of study to improve dye sensitized solar cells performance by TiO2 thickness and extract mangosteen pericarp as sensitized 

      Ismail, Daut, Prof. Dr.; Muhammad Fitra, Zambak; Muhammad Irwanto; Gomesh Nair, Shasidharan; Mohd Irwan, Yusoff (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      Based on the process and observation of this paper electrical energy conversion efficiency in dye sensitized solar cell performance is strongly influenced by the dye and the thickness Titaniuam dioxide. Both of these items ...
