Gomesh Nair, Shasidharan; Syafinar, Ramli; Muhammad Irwanto, Misrun; Mohd Irwan, Yusoff; M. R. Mamat; Uda, Hashim, Prof. Dr.; Norman, Mariun (Trans Tech Publications Inc., 2014-08)Dye-sensitized solar cell (DSSC) is part of the thin film family that consists of a TiO2 electrode coating which acts as a photo electrode, sensitizer from dye molecules soaked in the TiO2 film, electrolyte layer and a ... -
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) ... -
Performance improvement of dye sensitized solar cell by using recycle material for counter electrode
Gomesh Nair, Shasidharan; Mohammad Shafawi; Muhammad Irwanto; Mohd Irwan, Yusoff; Muhammad Fitra; Norman, Mariun (Trans Tech Publications, 2013)This project is to investigate the counter electrode material from two different carbon sources to fabricate dye sensitized solar cell (DSSC). The carbon sources are extracted from battery and pencil lead. The method to ... -
Photovoltaic powered uninterruptible power supply using microcontroller PIC16F628-I/P
Muhamad Irwanto, Misrun; Mohd Fareq, Abd. Malek, Dr.; Sasongko, P. Hadi; Gomesh Nair, Shasidharan; Mohd Irwan, Yusoff (Trans Tech Publications, 2014)Uninterruptible power supply (UPS) sits between a power supply such as wall outlet and devices to prevent undesired feature that can occur within the power source such as outages, sags, surges and bad harmonics from the ...
