A photovoltaic cell or photoelectric cell is a semiconductor device that converts
light to electrical energy by photovoltaic effect. If the energy of photon of light is
greater than the band gap then the electron is emitted and the flow of electrons
creates current.
However a photovoltaic cell is different from a photodiode. In a photodiode
light falls on n-channel of the semiconductor junction and gets converted into
current or voltage signal but a photovoltaic cell is always forward biased.
The photovoltaic (pv) power technology uses semiconductor cells (wafers),
generally several square centimeters in size. The cell is basically a large area p-n
diode with the junction positioned close to the top surface. The cell converts the
sunlight into direct current electricity. Numerous cells are assembled in a module
to generate required power

The fuel cells are considered as one of the most
promising devices for standalone/grid connected distributed
generations (DGs) due to its cleanliness, modularity and
higher potential capability. The barriers in the widespread
use of fuel cells are their slow response for sudden load
changes and higher installation cost. In this paper a
simulation study of dynamic behavior of NexaTM 1.2kW
PEM fuel cell with DC/DC boost converter is carried out for
compact design of PCU. The necessity for the requirement
of boost converter compared with cascaded two stack fuel
cell model is also addressed. Moreover the performance of
the simple DC/DC boost converter as power modulator for
NexaTM 1.2kW PEM fuel cell model is analyzed for varying
loads in order to control power flow for enhanced
performance.

Abstract—
In this project, the boost-inverter topology is used as a building block for a single-phase grid-connected fuel cell (FC) system offering low cost and compactness. In addition, the pro- posed system incorporates battery-based energy storage and a dc–dc bidirectional converter to support the slow dynamics of the FC. The single-phase boost inverter is voltage-mode controlled and the dc–dc bidirectional converter is current-mode controlled. The low-frequency current ripple is supplied by the battery which minimizes the effects of such ripple being drawn directly from the FC itself. Moreover, this system can operate either in a grid-connected or stand-alone mode. In the grid-connected mode, the boost inverter is able to control the active (P) and reactive (Q) powers using an algorithm based on a second-order generalized integrator which provides a fast signal conditioning for single-phase systems. Design guidelines, simulation, and experimental results taken from a laboratory prototype are presented to confirm the performance of the proposed system.
This paper proposes the design and development of Arduino based solar charge controller with sun tracking using PWM technique. This PWM technique is employed using ATmega328P on Arduino board. The Arduino is used to charge a 12V battery using 10W solar panel. The main feature of this charge controller is to control the load. During day time when load is not connected the battery gets charged from solar panel. When battery reaches peak value of 14.7V charging current & further charging is interrupted by Arduino. An inbuilt analogue to digital converter is used to determine voltage of battery, solar panel and current drawn by the load. A solar tracking system is also implemented such that panel is always kept at right angle to incident radiation.

Distributed energy resources (DER) based micro grid and Nano-grid framework is most technically viable bottom-top approach to sustainably meet ever-increasing demand of rural and urban communities. Recently the growth of DC operative home appliances like mobile and lap top chargers, ovens and hair dryer’s etc. are increasing and therefore a DC/DC converter is an efficient way to meet the electricity need from the local DER and helps in improving the system efficiency. This paper presents simulation results of a buck boost converter, MPPT algorithm (P & O method) for solar PV module and closed loop PI control system for obtaining constant 12 V and 24 V DC output voltage at DC bus. The proposed methodology is to extract maximum DC power from solar PV system and it is directly fed to DC load or DC Nano grid.

Design Of Charge Controller Using MPPT AlgorithmIJRES Journal
Recently non-conventional sources are in huge demand than the conventional sources of energy. Solar energy, though it is in great demand but it has low efficiency. So, to increase the efficiency of the system, we need to find the exact MPP. For this we employ a tracker called MPPT. The main aim will be to track the maximum power from the photovoltaic and feed the extracted power to the load via buck-boost converter. The purpose of this converter is to maintain the required voltage magnitude necessary for the load. In this paper, I have used P&O Algorithm to get the maximum power point and for efficiently designing the charge controller.
The solar energy is converted to electrical energy by photo-voltaic cells. This energy is stored in batteries during day time for utilizing the same during night time. A charge controller, or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.
