Toshiba is a Japan-headquartered multinational conglomerate that manufactures and sells various products and services including information technology and communications equipment and systems, electronic components and materials, power systems, industrial and social infrastructure systems, consumer electronics, household appliances, medical equipment, office equipment, lighting and logistics and more.
In September 2017, Toshiba announced the fabrication of a film-based perovskite solar cell mini module with an impressive conversion efficiency of 10.5%. This efficiency rate was achieved in a 5 cm x 5 cm module and is stated by the company to be the highest yet recorded in a multi-cell mini module. In June 2018, New Energy and Industrial Technology Development Organization (NEDO) and Toshiba announced the world's largest film-based perovskite photovoltaic module. The module is 703cm2 (24.15 x 29.10cm) and achieves a power conversion efficiency (PCE) of 11.7%, overcoming the difficulties of increasing size and efficiency at the same time.
Having demonstrated the possibility of increasing area and efficiency of a film-based module, and achieving a conversion efficiency of over 10%, Toshiba will focus on increasing the module size and conversion efficiency, through measures including changing the composition of the perovskite material and by process improvements.
