Can halved silicon wafer solar cells improve PV module power?
One method to improve PV module power is to produce PV modules using halved silicon wafer solar cells. It is already known that by using halved cells instead of standard full-size cells, the cell-to-module power loss can be noticeably reduced, by reducing electrical series resistance related losses , .
What is the characteristic resistance of a solar cell?
The characteristic resistance of a solar cell is the cell's output resistance at its maximum power point. If the resistance of the load is equal to the characteristic resistance of the solar cell, then the maximum power is transferred to the load, and the solar cell operates at its maximum power point.
What causes series resistance in a solar cell?
Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts.
Does series resistance affect a solar cell at open-circuit voltage?
Series resistance does not affect the solar cell at open-circuit voltage since the overall current flow through the solar cell, and therefore through the series resistance is zero. However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance.
What is a polycrystalline silicon PV module?
A polycrystalline silicon PV module consists of a back sheet (polymer or glass), encapsulate, cell, electrode, ribbon wire and glass from the bottom to the top . Single silicon solar cells shown in Fig. 1 (a) typically produce around 0.6 V in direct sunlight.
Do different resistivities affect P-Topcon solar cells?
This study investigated the effects of different resistivities on p-TOPCon solar cells. The results indicate that lower resistivity wafers have a higher implied open-circuit voltage (iVoc) value, but higher carrier mobility due to the low resistivity leads to an increase in saturation current density (J0).
