A photovoltaic cell includes a p-type copper-indium-gallium-selenide absorber layer, where a content of Cu, In, and Ga in a first portion of the p-type copper-indium-gallium-selenide absorber layer satisfies the equation Cu/(In+Ga)&#x2266;0.3, and where the content is measured in atomic percent.

Provided herein are improved methods of laser scribing photovoltaic structures to form monolithically integrated photovoltaic modules. The methods involve forming P1, P2 or P3 scribes by an ablative scribing mechanism having low melting, and in certain embodiments, substantially no melting. In certain embodiments, the methods involve generating an ablation shockwave at an interface of the film to be removed and the underlying layer. The film is then removed by mechanical shock. According to various embodiments, the ablation shockwave is generated by using a laser beam having a wavelength providing an optical penetration depth on the order of the film thickness and a minimum threshold intensity. In one embodiment, material including an absorber layer is scribed using an infrared laser source and a picosecond pulse width.
