Background technology
In the course of work of solar cell module, if there is shadow occlusion some or certain solar cells, meeting
Cause the output with the concatenated other batteries of shade battery that can all consume on the battery, this energy expenditure can lead to battery PN
The partial breakdown of knot, and cause hot-spot, here it is hot spot effects.Solar cell meets with due to hot spot effect in order to prevent
It being damaged, common solution is to install bypass diode additional on the basis of primary circuit, when light is not blocked, each two pole
Pipe is in reverse bias, and each battery is producing electricl energy.It can stop producing electricl energy when a battery is blocked, become a height
Valued resistor, while other batteries promote its reverse bias, lead to the diode current flow for connecting battery both ends, flow through and be blocked originally
The electric current of battery shunted by diode.
In the prior art, Fig. 5 is a kind of existing common solar energy half battery photovoltaic module, general using double group batteries
Connection in series-parallel shares the connection type of a diode.Such circuit is when most of partial occlusion occurs for component, meeting
Causing component output power to be exported than the component power of conventional full wafer cell piece reduces, and can reduce power generation in practical applications in this way
Amount.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of half photovoltaic cell component of full tandem type, when half
When piece battery component blocks outdoors, output power and generated energy are improved.
The technical solution of the utility model is：A kind of half photovoltaic cell component of full tandem type, including it is multiple concatenated
Battery strings group and multiple bypass diodes being arranged in parallel respectively with each battery strings group one-to-one correspondence, each battery strings group packet
A battery strings or at least two concatenated battery strings are included, each battery strings include multiple concatenated half cell pieces.
In the utility model there are many arrangement modes of battery strings group, preferably, multiple battery strings groups parallel arrangement and
It is sequentially connected in series to form a battery string location, multiple battery string locations continue to be sequentially connected in series.

A string group diode in parallel.
Compared with prior art, the beneficial effects of the utility model are embodied in：
The utility model no longer first carried out like that with conventional half component it is in parallel connect again, the utility model is by battery strings group
All series connection, it is ensured that the half cell piece of each bypass diode management and control fair amount, such as existing conventional half
For piece photovoltaic cell component, the cell piece quantity of each bypass diode management and control of the utility model is not higher than conventional light in the market
Lie prostrate component 10 or 12, mismatch may be used also to improve component output power caused by can not only reducing string resistance in this way
