Zeer refrigerator is an evaporative cooling system which use evaporation of water to lower temperature inside the refrigerator. Its rate of evaporation which affects rate of heat loss depends on surface area of the refrigerator. Conventional Zeer refrigerator can’t be built in large scale because its efficiency and terminal temperature difference between inside refrigerator and ambient...

Perovskite solar cells have several advantages over traditional solar cells such as the ability to control the film morphology during the deposition and crystallization of the perovskite layer. The efficiency of perovskite solar cells can be modified using physical and chemical techniques to achieve better efficiencies. In this paper, we study the fabrication of typical inverted structure...

Solar cell I-V characteristics curves are basically representation of relationship between the current and voltage at the existing conditions of irradiance and temperature. I-V curves provide the information required to configure a solar system. The parameters values of V$_o$$_c$, I$_s$$_c$, V$_m$, I$_m$ and P$_m$, which can be experimentally measured. However, the circuit parameters reverse...

The 5th May 2014 Chiang Rai earthquake is the largest earthquake in Thailand. The mainshock followed by thousands of aftershocks which located in both Pan segment (PS) and Mae Lao segment (MLS) of Phayao Fault Zone (PFZ). This complication of aftershock pattern leading to the intriguing question about the origin of mainshock whether it’s come from MLS or PS. The seismological and...

Solar radiation is important to all living organisms and it is the energy source for solar technologies such as photovoltaic and solar thermal systems. Generally, the amount of incident solar radiation can be obtained from ground-based measurements. However, the number of solar radiation monitoring stations is very limited. In this work, the artificial neural network (ANN) was proposed to...

Near infrared solar radiation (NIR) represents a large amount of the total energy of the solar spectrum. NIR is important for applying to remote satellite approaches in order to investigate an atmospheric water vapour and for other solar energy thermal applications. However, it was less investigated compared to another solar spectrum bands. Additionally, measurements of NIR are also scarce....

Water vapour is a main natural greenhouse gas and has impact on the atmospheric system. Atmospheric water vapour can be quantified as precipitable water vapour (PWV). In general, PWV can be derived from radiosonde and spectral solar radiation measurement data. However, the spatial distribution and temporal frequency of the measurements are usually limited due to high equipment and operational...
