Chlorine activated stacking fault removal mechanism in thin film CdTe solar cells: the missing piece
Publikováno v:
Nature Communications, Vol 12, Iss 1, Pp 1-9 (2021)
Stacking fault removal and improvement in CdTe solar efficiency is known to be correlated, yet the nature of the relationship is not well-established. Here, the authors explain the passivation process responsible for this improvement, and also elucid

Spray coating is an industrially mature technique used to deposit thin films that combines high throughput with the ability to coat nonplanar surfaces. Here, we explore the use of ultrasonic spray coating to fabricate perovskite solar cells (PSCs) ov

Soiling of solar module cover glass is a serious problem for solar asset managers. It causes a reduction in power output due to attenuation of the incident light, and reduces the return on investment. Regular cleaning is required to mitigate the effe

The presence of soiling on photovoltaic modules reduces light transmission through the front cover glass to the active absorber, thereby reducing efficiency and performance. Current soiling mitigation techniques are expensive and/or ineffective. Howe
