Production technologies such as silver-paste screen printing and firing for contact formation are therefore needed to lower the cost and increase the volume of production for crystalline silicon solar cells.
The last 15 years have seen large improvements in crystalline silicon solar cells, with efficiencies improved by over 50%. The main drivers have been improved electrical and optical design. Electrical improvements include improved passivation of contact and surface regions and a reduction in the volume of heavily doped cell material.
The peak theoretical efficiency in a crystalline silicon solar cell based on a single homojunction and a bulk silicon energy bandgap of 1.1 eV is 30% under 1 sun AM 1.5 illumination.
Such features have increased silicon cell efficiency to a recently confirmed 24.7%. Recently, progress has been made in transferring some of the corresponding design improvements into production with commercial cells of 17–18% efficiency now available, world record values of a mere 15 years ago.
Both the industrialization status and future development trend of high-efficiency crystalline silicon solar cells are also pinpointed. Export citation and abstract BibTeX RIS
