The low intensity would enhance the influence of leakage current and decrease FF as result [ 11, 12 ], while the low temperature will cause current blocks by the heterojunctions in solar cells [ 13, 14 ]. Besides, low temperature causes blue-shift of bandgap that decrease current in top cells, leading to decay of output power.
Theoretically, increasing the film thickness of single junction organic solar cell can achieve a higher JSC, however the lower FF limits the PCE due to recombination losses caused by lower carrier mobility.
A lean production chain with low-temperature processes and carrier selective hetero-structure for excellent passivation are main advantages of silicon heterojunction (SHJ) solar cells. Due to their higher open circuit voltage and their lower temperature coefficient of power, they offer a superior module performance compared to homojunction cells.
For solar cells, low temperature improves open-circuit voltage due to the low recombination rate and temperature-bandgap dependency, but reduces short-circuit current due to the absence of absorption of low-energy photon caused by the increase of bandgap.
19.9% efficiency is obtained in homojunction tandem organic solar cells, which is currently the highest reported. In the field of organic photovoltaics, the power conversion efficiency of single junction solar cells continues to improve.
The most apparent approach for interconnection at very low temperatures is to adapt the interconnection materials, i.e., suitable solder alloy, flux or ECA. Besides the material availability on the market and long-term stability in the PV module, this solution is compatible with existing industrial stringers for interconnection.
