“…El-Sebaii and Shalaby [4] recorded that the maximum difference between inlet and outlet air temperatures was about 28°C for upper channel at a 0.0223 kg/s flow rate and 580 W/m 2 solar intensity. It has been also suggested to insert an absorbing plate into a panel to have a double pass channel where the air flows from above and then below the absorber plate [13][14][15] or vice versa [16][17][18]. In general, the principle of using doubles pass or passing the flow from above and then from below is to increase the airflow path length inside collector.…”

“…Such solar cells can even be generated using agricultural waste [35]. These new technologies are highly flexible and can form the basis of thermoelectric solar air collectors [36] as well as double collectors that work as both air heaters and photovoltaic electrical power generators [37]. The essential question is that the adsorbed hydrogen plays the same role as the doping in conventional silicon or germanium semiconductors and that a significant level of adsorbed hydrogen is required to achieve a good TEP.…”

The Seebeck coefficient of vapour grown carbon fibres and carbon fibres made from polyacryolytrile precursor has been studied as a possible parameter to control hydrogen storage inside. The sign of the Seebeck coefficient gives the sign of the dominant charge carriers in the fibres, and when hydrogen is absorbed by the carbonaceous material, mainly as H ? , it acts as a positive charge carrier. A simple two-band electronic model has been considered to explain the influence of hydrogenation on the Seebeck's coefficient of these carbon microfibres. The most favourable condition for hydrogen adsorption is a moderately low pressure of hydrogen. Furthermore, it was observed that outgassing is more pronounced than expected in some types of fibres, thereby supporting the proposed presence of hydrogen generated during the manufacturing process.

Since 1970's a lot of research and development has been done on various modules of PVT. Many innovative models of PVT has been developed and put forward and validity has been evaluated by experimental data.This paper presents the various performance parameters of different types of modules which include both Air and Water as collector. Effects of various parameters, namely interest rate, life of the system and the maintenance cost have been taken into account. A comparison is made keeping in view the energy matrices. The study has been based on electrical, thermal and energy output of the HPVT air collector. An analysis of an actively cooled combined of photovoltaic thermal system consisting if a linear solar concentrator and tubular absorber has been presented here. An attempt has also been made to evaluate the thermal performance of two types of hybrid photovoltaic thermal (PV/T) air collector system for composite climate of New Delhi. This paper also presents the performance evaluation of a hybrid photovoltaic thermal (Semi transparent PVT) double pass facade for space heating. This paper presents theoretical and experimental analysis of double pass solar air collector with and without porous material. A novel solar air collector of pin-fin integrated absorber designed to increase the thermal efficiency is also discussed here. Keywords: Hybrid photovoltaic thermal (HPVT) air collector, solar air collector, passive and hybrid (PV/T) active solar still, thermal performance, energy and exergy efficiencies. I. INTRODUCTIONIncreasing cost of fossil fuels has compelled scientists to look for different options to meet energy requirements keeping in view that such options are economical, abundant in nature and have low maintenance cost. Over the years, scientists have studied various options available such as nuclear energy, wind energy, bio mass, fuel cell, solar energy, etc. Studies have shown that amongst available sources of energy, solar energy appears to be freely available, more economical and truly environment friendly than other sources of energy available [1]. Solar energy can be utilized as electrical energy, thermal energy or a combination of both. Hybrid photovoltaic thermal (HPVT) air collector system can collectively generate electrical and thermal energy. The HPVT system can be used as air collector/water collector. A HPVT air collector consists of a PV module with an air duct mounted below the PV module. The air is passed through the duct by using a fan. The air gets heated by using the thermal energy available at the bottom of the PV module. In case of HPVT water collector, water is used in place of air [2]. Thus, an HPVT system can be used as (1) Air collector (2) Water collector
