Two main scenario have been proposed for the progenitor channel: a single massive star or a binary system. They represent a quite rare class of supernovae (~34% of core-collapse) and only in the recent time with the upcoming of several surveys it was possible to build up a sample of objects being statistically significant. In this scenario, the Palomar Transient Factory (PTF) and the intermediate PTF (iPTF) bring their contributions; infact, unlike all their predecessors, those were untargeted surveys. The surveys took place through the use, mainly, of the P48 and P60 telescopes at the Palomar Observatory but several other facilities were involved to implement the collected data set (e.g. P200, NOT, LCOGT, Keck, Gemini...) on the window of time 2009-2016. These surveys have been a forerunner for the upcoming Zwicky Transient Facility (ZTF) which already saw its first light and will be fully operative in early 2018. I will present the SNe Ib/c sample found from PTF and iPTF. The analysis is mainly focused on the photometric dataset, in order to estimate the explosion parameters and to investigate the progenitor system.​
